Transmission

This adapter kit is designed for exclusive use with the GM TH350 automatic transmission. This GM automatic was commonly found stock in vehicles from 1969-81. It was used in both pickups and car applications. The TH350 has aluminum, 1 piece case and is 21.5” in length. It was used in both the 4WD pickups and 2WD applications. These transmissions are identical except when it comes to the output shaft stickout length. The 4WD transmission used an adapter to bolt this transmission to its stock transfer case. With this adapter removed, the stock output shaft protrudes from the back of the transmission case approximately 1”. On 2WD vehicles, these transmissions used 3 different tailhousings. The lengths of these tailhousings are 6”, 9”, and 12”. The output shafts lengths correspond with these tailhousing lengths. This transmission is one of the most popular choices for engine and transmission conversions due to the overall length of 21-1/2”. The 1st gear ratio is 2.52:1; 2nd 1.52:1, and a 3rd gear ratio of 1:1.
