The T18 can be identified by the case casting numbers T18 or 13-01. The improvements include more main drive pilot bearings, no bushing under third gear and no loose rollers under second gear. The later units also include larger synchro cones on third and fourth and die cast forks. The T18, like the T98, can be easily adapted to various engine and transfer case combinations.

The New Venture Model 4500 transmission offers the best possible gear ratio available for off-the-road conditions. The extremely low first gear ratio along with the overdrive 5-speed combination makes this transmission very desirable. The transmission was introduced in both the GM and Dodge vehicles 1992. The NV4500 is a 5-speed, constant-mesh, manual transmission. All forward gears are fully synchronized. The ultra low 1st gear has a ratio of 5.61:1 and the 5th gear is an overdrive gear that has a ratio of .73:1. The transmission case is made of a cast-iron material and the gear case cover is an aluminum alloy. The low profile of the top cover provides excellent clearance for 4WD after market conversions. Unlike the older GM and Ford 4-speeds, the shift tower location has been relocated farther back, approximately 9 1/2″ from the bell housing on the transmission case, to provide for easier accessibility.

The New Process 435 transmission was used in Chrysler (1963-1993 ), Ford (1964-1987 ) and G.M. (1963-1972 ) trucks. These transmissions have a 6.68 to 1 1st gear ratio in all three applications. While Chrysler and G.M. applications also offered a 4.56 to 1 ratio. The Ford versions adapted real well into the early Broncos (1966-1977 ) and late Jeep CJs (1980-1986 ) with only minor modifications. While other conversions require more modifications including drive shafts lengths. The NP 435 is a HD transmission with cast iron case and aluminum cover. It is synchronized 2nd through 4th gear with sliding gear for 1st and reverse. They ran a solid cluster on needle bearings and a tapered main drive gear bearing on most applications. Our rebuilt transmissions include all new bearings, seals, gaskets and whatever it takes to make them a good reliable transmission. These transmissions are available as stock replacement or as conversions.

SM 465 The GM Muncie SM 465 was used in GM trucks from 1968 to 1991. These transmissions work real well in 1980 and later CJ’s when doing GM V8 engine swaps or replacing the blown up stock transmissions between a GM engine and the Dana 300 transfer case. The SM 465 is a top loaded HD transmission with iron case and cover. It is synchronized 2nd through 4th. It has a 6.54 ratio sliding 1st gear. We offer these transmissions completely rebuilt ready to install as an exact replacement or with an adapter for conversions. Our rebuilds include everything necessary to make them as dependable as possible.

SM 420 The GM Muncie SM 420 transmission was used in GM trucks from 1948 to 1967. These transmissions are popular with “ROCK CRAWLERS’ because of it’s 7.06 to 1   in 1st gear. The SM 420 is a top loaded HD transmission with iron case and cover. It is synchronized 2nd through 4th with a sliding 1st and reverse gear. When adapting the SM 420 into the shorter jeeps it requires more modifications than some of the other choices. But in the end you will have the lowest 1st gear available. We offer these transmissions completely rebuilt ready to install as an exact replacement or with an adapter for conversions.
