Individual Major Parts for New Venture NV4500 5 Speed Manual Transmissions

New Venture Gear (NVG) was a joint venture between Chrysler's New Process Gear (NPG) and GM's Hydromatic Muncie Transmission Division that was formed on February 6, 1990. The NV4500 5 speed manual transmission is primarily a New Process Gear design that was assembled at the Muncie Transmission plant from late 1991 to mid-2006. Even though the joint venture ended in 2002 when GM sold it's 36% stake in the company to Daimler Chrysler, the Muncie plant continued to build NV4500 transmissions for Dodge to the 2005 model year and GM for the 2007 model year. The quality of genuine New Venture Gear components is excellent, and we still continue to stock any genuine NVG parts we can find, but today, most of the NV4500 parts we stock will be high quality replacement parts manufactured overseas.

product note

All Dodge and 1992-1995 GM New Venture NV4500 transmissions use Input Shaft Bearing Retainers with a nose for the clutch release bearing to ride on. 1996 and newer GM transmissions have a flat front retainer for mounting a concentric slave cylinder. 1992-1995 GM Input Bearing Retainers have a 5-1/8" bell housing index diameter, all Dodge and 1996-up GM have a 5.6" index diameter. The 1992-1995 GM Input Bearing retainers also have a smaller transmission pilot size and bolt pattern so they are not interchangeable with Dodge and 1996-up GM Input Bearing Retainers.

Cases and Housings

top_page
product note

All our Housings and Cases are genuine NVG parts. Most of our remaining inventory is new takeout parts from brand new transmissions we disassembled for parts. We do not sell any of the imported aftermarket replacement cast iron tailshaft housings for Dodge transmissions due to poor machining accuracy of every single one of these we have checked from 2006 to 2013 (See Tech Article). Dodge and GM 4x4 tailhousings have the same rear bolt circle, but the hole clocking and housing lengths are consderably different. For 4x2 applications, GM used a fixed output while Dodge 4x2 models have a long, slip type rear output. For a NV4500 conversion into a 4x4 with a remote mount transfer case. the compact, GM C-Truck 4x2 aluminum housings are the best choice for most conversions.

tech note

Dan the Gear Man® Tech Note:
New Venture made a number of different 4500 main cases for General Motors and Chrysler. All are made of cast iron and have both left and right PTO covers. The three primary variations found in Dodge and GM applications all have identical top cover and rear housing bolt patterns. The differences are the front case face and reverse idler mounting.

Countershafts (Lower Shafts)

top_page
product note

The original countershaft used in the NV4500, had replaceable front gears (see QU10090 and our Countershaft Gearing). The shaft was changed to a one-piece design in 1995 after GM discontinued the 6.34:1 reverse and switched to the same 5.61:1 reverse ratio that Dodge used. In 1997, New Venture redesigned the NV4500 Countershaft for a 5.04:1 reverse gear ratio. The 1997 and newer countershaft is NOT interchangeable with 1992-1996 Countershafts. 

tech note

Dan the Gear Man Tech Note:
Typically, Countershaft gear tooth failures occur from one of three causes: low or improper oil, clutch pilot bearing failures (which cause misalignment of the input shaft), and excessive horsepower/torque (over 275hp/600 lb-ft of torque). Broken 3rd gear teeth are almost always caused by exceeding the demonstrated 600 lb.ft input strength limit of the NV4500.

Countershaft Gears

top_page
product note

Early production NV4500 transmissions used a modular Countershaft (see QU10090) that featured replaceable, press-fit front gears for gear ratio changes. All 1992-1994 transmissions used the modular design. We have also seen these countershafts used on a number of 1995 transmissions. A few may have been used as late as 1996 model year trucks with low production drive-train combinations. The Countershaft 5th gear is located behind the countershaft rear bearing and its is supported by QU10141 Caged Needle Bearing.

Main Drive Gears (Input Shafts)

top_page
product note

We stock a selection of Original Equipment (OE) and quality replacement NV4500 Main Drive Gears. All applications except 1992-1994 GM models use a 22 tooth input gear. 1992-1994 GM trasnsmissions with the 6.34:1 1st and reverse gear have 20 tooth input shafts. The two biggest killers of Main Drive Gears are: #1 Problem is a failed clutch pilot bearing or bushing which chews up the tip and can cause gear tooth breakage from misalignment. #2 Problem is running the transmission low on oil or with the wrong oil. Another cause is excessive horsepower which can cause either tooth breakage or the shaft to twist off. While we do offer an 1-3/8" input shaft kit for Dodge applications to minimize the chances of the shaft twisting off, the rest of the transmission is still maxing out at around 600 lb-ft of input torque.

tech note

Dan the Gear Man® Tech Tip:
Always inspect the tip of your input shaft for wear. Worn pilot bearings often damage or groove the input shaft pilot.

Mainshafts (Rear Output Shafts)

top_page
product note

Most NV4500 transmissions behind Diesel engines will need a Mainshaft sometime during the vehicle life-cycle due to wear in the 5th gear area. Mainshaft 5th Gear issues are mostly caused by the inability of stock and full-spline Mainshafts to adequately support the 5th Gear.  Mainshaft Interchangeability: The NV4500 transmission is a marvelously adaptable transmission for use in any number of conversion scenarios. As far as the main case and reverse through 4th gearing, any 4500 Mainshaft can be swapped into any 4500 transmission. However, such a swap will also require one or more other changes which may include the Mainshaft 5th gear, Mainshaft Nut Set, Mainshaft Spacer or Vibration Damper, Speedometer Drive, and Tailshaft Housing.

tech note

Dan the Gear Man® Tech Note: Guys and Gals, we discuss the pros and cons of the full spline designs in my tech article: 5th Gear Failures and Solutions. The advantage of these shafts is they will get you back on the road for a reasonable amount of time and at a low cost. The disadvantage is no full spline shaft will prevent 5th gear loss because they do not address the cause of the problem. All full spline shafts of this type, made by anybody and sold by anybody are inherently weaker than stock and Torque King® shafts due to the groove machined in the shaft for the 3 piece thrust washer set. 

Update: Torque King® Shafts are No Longer Available. Folks, the preceding Note was written in 2005. Everything still applies today, except we discontinued the Torque King® design a year or two after I retired in 2011. We never had a single Torque King® Shaft returned to us for a fifth gear failure, but despite the success of the product, the advancing age of NV4500 equipped trucks (most were built between 1994 and 1999) combined with the 6 figure price tag to renew the production contract caused the next generation to discontinue the product. I was called back from full retirement to update the Tech Notes at the end of 2016 and updating this Tech Note was hard, but today, the only game in town for the Dodge NV4500HD is a full spline shaft.

Most of our stock of NV4500 gearing will be quality replacement parts, but we still have some genuine gearing made by NVG before the Muncie plant closed in 2006. The New Venture NV4500 was built in both wide and medium ratio versions from 1992-1994, but only the medium ratio was produced from 2005 on. New Venture also made a reverse gear ratio change from 5.61:1 to 5.04:1 effective with the 1997 model year, For mainshaft gearing 3rd, 5th, and Reverse Gears are available with different teeth counts depending upon the year and model of your transmission. In addition, GM used unsynchronized reverse gears from 1992 to 1998. Dodge NV4500HD transmissions have a unique to application,larger bore mainshaft fifth gear. If your transmission is not original, ALWAYS verify the gearing you have before ordering parts!

tech note

Dan the Gear Man® Tech Note 1: To change from an unsynchronized to synchronized reverse requires a synchronized reverse gear of the same tooth count as your original, a QU10710 (OE) or QU10204 (Replacement) Reverse Clutch, QK1099 Synchro Strut Kit, and QU10003 Synchro Ring.

Dan the Gear Man® Tech Note 2: Third Gear is the most common gear to break in enhanced horsepower applications (over 600 lb-ft engine torque).

Mainshaft Spacers and Dampers

top_page
product note

GM transmissions all use some type of Spacer or Damper between the Mainshaft 5th Gear and nut set or yoke. These parts make GM transmissions generally more resistant to 5th gear failures when compared to Dodge units. In fact, GM 4x2 transmissions almost never suffer from that malady.

photo

QU10172 GM NV4500 4x4 Vibration Dampener Was used instead of QU10173 Spacer on both gas and Diesel 4x4 transmissions with certain year and engine combinations. The Dampener is located between the back of the mainshaft 5th gear and the nut set. This hefty part is designed to be an interference fit on the mainshaft, so, besides minimizing felt vibration, it helps keep the the fifth gear from loosening up and working the nut off. However, if the dampener does not fit the shaft correctly, it will accelerate the loosing of the mainshaft nut due to centrifugal force.

QU10173 GM NV4500 4x4 Spacer was used in lieu of QU10172 Vibration Damper on both gas and Diesel GM New Venture NV4500 4x4 transmissions with certain year and engine combinations.

Reverse Idler Gears and Shafts

top_page
tech note

1996 and earlier Early NV4500 transmissions utilized a two-plane reverse with either 5.61:1 or 6.34:1 Reverse Gear ratios. With a two-plane reverse, the front half of the wide reverse idler gear receives power from the countershaft and it uses the rear half to transfer power to the large diameter mainshaft reverse gear. The 5.04 ratio Single-plane reverse was introduced for 1997 model year trucks. The power transfer is inline between the countershaft, narrow reverse idler gear, and small diameter mainshaft reverse gear. The idlers, countershafts, reverse gears, and transmission cases are not interchangeable for the two types of reverse gear systems. Our Reverse Idler Gears and Shafts are accurately made and precision ground for precise fit, quiet operation, and long bearing life.

Shift Covers

top_page
product note

The 1992-1994 GM and 1992-1997 Dodge NV4500 Transmissions used a top cover with and integral shift tower. Transmissions with the early covers are more difficult to remove and install unless your truck has a removable cab floor pan. The early covers worked well, but they are subject to wear in the concave ball seat that supports the shift stub. A badly worn seat can cause all kinds of shifting difficulties in an otherwise sound transmission. The later design, flat top cover with a removable tower is less prone to wear in the shift tower. Early and late covers are interchangeable as far as fitting the transmission goes, but you have to make sure you order the correct stub or tower to match your shifter when changing top cover types.

tech note

Dan the Gear Man® Tech Tip: If you have an older NV4500 with the integral shaft tower (GM to 1994, Dodge to 1997), and you have trouble shifting into gear (usually 3rd or 4th) the culprit may be a worn shift tower seat. A very strong spring exerts down pressure against the shift stub. Over time, the stub will wear into the integral aluminum seat. In extreme cases, the seat wears to the point where the shift stub base will hit the shift rail. When this happens, the friction between the rail and stub can make shifting very difficult or cause the shifter stub to jump out of the rail notch. The solution is to replace the cover plate or cover assembly.

Shift Forks

top_page
product note

The NV4500 transmission does not usually have problems with Shift Fork wear except for some GM models with one-piece Reverse Forks. When significant wear does occur, the root cause is usually grossly excessive shaft end-play caused by either oil problems or just a lot of miles. The fifth and reverse forks can be replaced without much trouble, but if you need to replace the 1-2 or 3-4 forks, cover modification is required. See my TM1003 illustrated NV4500 Service Manual for Top Cover service procedures and order either QK1144 or QK1145 Top Cover Service Kit from our NV4500 Small Parts Page.

Shift Stubs and Towers

top_page
product note

Early versions of the NV4500 Transmission used a spring loaded shift stub that was retained by one of 2 styles of twist-lock cap (See QU10733). A redesigned shift cover featuring a bolt-on removable tower replaced the original design starting in the 1995 model for GM and 1998 for Dodge (See QU10706). Shift Stub Kits for the early covers are listed on our NV4500 Kits catalog page. Spacers, bolts, and bushings for bolt-on type towers are listed on both our NV4500 Kits and NV4500 Small Parts catalog pages.  If you have an early cover, any of our Shift Stub Kits can fit your cover but you will need to match the stub connection to your lever.  For Bolt-On type towers, we still have QU10047 1998-2002 Dodge (14mm stub) and QU10703 1994-2000 GM (16mm stub) towers. The following towers are no longer available: QU10737 2003-2005 Dodge, QU10737 GM 2001-2007, QU10218 GM right hand drive.

product note

The 4th, 5th, and Reverse Gear Clutches are replaceable on all New Venture NV4500 transmissions.

tech note

Dan The Gear Man® Tech Tip: When servicing your transmission, always check for wear on the internal splines of the 5th gear clutch and the corresponding splines in the countershaft. The clutch is a loose slip-fit on the countershaft. On a new shaft with a new clutch, a dial indicator mounted to the countershaft and indicating off a synchro tooth will read about 0.10".

Synchronizer Hubs and Sleeves

top_page
product note

We stock individual synchro clutch hubs and sleeves. Synchro clutch teeth wear issues with NV4500 synchronizer sliding sleeves or rings is fairly common. The unsynchronized reverse gear sleeve on 1992-1998 GM NV4500 transmissions is especially prone to clutch tooth wear. For synchronized gears, wear on the leading edge of the clutch teeth usually is caused by one or more of these causes: wrong or contaminated oil, clutch release issues, excessive transmission shaft end-play, shift fork wear, or use of bronze instead of lined synchro rings. The face of 3-4 clutch hubs are also subject to wear from either 3rd gear or the thrust bearing.

About 40 miles from our location, East Rosebud Creek Tumbles out of the Beartooth Mountain Wilderness. Across the Creek are scorched remnants of a major forest fire that swept down the Canyon and out into the plains in 1996. Running alongside the creek is a very popular 26 mile long hiking trail that takes you into the heart of the wilderness as the trail winds it's way from Alpine Lake on the north side of the Beartooth Mountains to Cooke City, Montana near Yellowstone Park.

(Continued from Top of Page)

.... The NV4500 transmission was initially designed to allow for close, medium, and wide ratio models, plus there were plans for a NV4600 6 speed with a double overdrive. Only the wide and medium ratio 5 speed versions saw production. GM used the wide ratio version with 6.34:1 1st and reverse gear ratios in 1992 to 1994 trucks. Dodge used the medium ratio version with 5.61:1 1st and reverse gears from 1992-1996 as did GM for 1995-1996. All 1997-2004 Dodge and 1997-2007 GM NV4500 transmission have a 5.61:1 1st gear ratio and a 5.04:1 reverse gear ratio. All Dodge NV4500 and 1999-2007 GM versions have a synchronized reverse gear.
