Tech Note 1: Case Specs
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. Listed below are the approximate Center to Center Bolt Pattern Dimensions and Input Retainer dimensions:

1992-1995 GM: Used with 6.34:1 Reverse (1992-1994) and 5.61:1 Reverse (1995).
Torque King p/n NV4500GME, Casting# 16812
Top: 10.078"
Bottom: 10.394"
Top to Bottom: 4.685"
Pilot for Input Shaft Retainer: 3.625".
Input Shaft Retainer Bolt Circle: 4.375"

1994-1996 Dodge and 1996 GM: Used with 5.61:1 Reverse.
Torque King p/n NV4500E, Casting# 18157 (Dodge)
Top: 10.078"
Bottom: 9.378"
Top to Bottom: 6.043"
Pilot for Input Shaft Retainer: 4.102".
Input Shaft Retainer Bolt Circle: 4.85"

1997-2005 Dodge and 1997-2007 GM: Used with 5.04:1 Reverse.
Torque King p/n NV4500L, Casting# 23167 or 33903
Top: 10.078"
Bottom: 9.378"
Top to Bottom: 6.043"
Pilot for Input Shaft Retainer: 4.1".
Input Shaft Retainer Bolt Circle: 4.85"

Tech Note 2: Early vs. Late Cases
Early and Late NV4500 Transmission cases are not interchangeable. When first introduced, the NV4500 Transmission had a dual-plane reverse where the power transfer path from the counter shaft to the mainshaft reverse gear is offset. The front half of the 2-3/4" long reverse idler gear engages the countershaft, while the rear half drives the mainshaft reverse gear. Since there are no teeth on the counter shaft below the mainshaft reverse gear, that gear can be larger diameter and have more teeth (39). The 1992-1996 transmissions have a 6.34:1 reverse for 1992-1994 GM and 5.61:1 reverse for all Dodge and 1996 GM.

Effective with the 1997 model year, New Venture NV4500's use a single-plane reverse where the power transfer path from the countershaft to the mainshaft is inline. The full working width of the narrow, 1-1/2" wide reverse idler gear is inline with both the countershaft gear teeth and mainshaft reverse gear teeth. Since the countershaft drive teeth are now located directly under the mainshaft reverse gear, the mainshaft reverse gear diameter had to be reduced to the point it now has only 35 teeth. Less teeth means less gear reduction. All 1997 model year and newer NV4500 transmissions have a 5.04:1 Reverse.

The difference in the transmission case reverse idler gear pocket and mounting boss for the single and dual plan reverse means the countershaft, mainshaft reverse gear, reverse idler gear, and reverse idler shaft are NOT interchangeable between early and late cases.

Tech Note 3: Sealants
Early production NV4500 Transmissions used an anaerobic sealant (QU90003) to seal between the main case and input bearing retainer, top cover, and rear housing. Mid-production units used anaerobic sealant just on the input retainer and RTV for everything else. Later production transmissions used black RTV Sealant (QU90006 or QU90005) for everything. Either type of sealant works fine (except the PTO covers ALWAYS should be sealed with RTV), but I prefer RTV for all components. Regardless of which sealant you use, make sure excess sealant does not block the lube access hole at the top of input retainer pilot that fits into the transmission case! Also, the threaded holes in the main case for the four retainer bolts and 12 PTO bolts are open ended, so you must use new bolts with factory applied threadlocker or apply Threadlocker (S24200) to your existing bolts to prevent oil seepage past the bolt threads. See my TM1003 NV4500 Shop Manual or VSG1003DVD NV4500 Overhaul Video for more information.

Tech Note 4: Common Causes of Cracked Cases
If your original transmission main case cracked, check for broken motor mounts. A broken motor mount can cause the engine to twist beyond what the transmission case can handle. Loose Transmission mounting bolts can also cause a case to crack. A transmission that is run out of oil will frequently have a cracked case, but it may be difficult to determine if the case cracked before or after the lube oil was lost.
