Detailed Description

Pioneer Cables 761011 is a transmission sealing component used in variable pitch automatic transmission setups. It is listed for a wide range of classic Buick Riviera, Cadillac Eldorado, Oldsmobile Toronado, Chevrolet Impala, and Pontiac GTO applications, along with other GM models from the 1965-1981 model years. The seal is intended for direct replacement use where the original turbine shaft seal has worn, hardened, or begun leaking.

Because this seal is tied to specific transmission families and notes such as THM400, THM425, THM475/M40, and 3L80, verifying the transmission code and vehicle configuration is important before installation. Pioneer Transmission Components are positioned as exact-fit replacement parts, which helps support proper sealing performance in the intended application.

Installation Notes

Confirm the transmission family and vehicle notes before installation, especially where the listing specifies THM400, THM425, THM475/M40, or 3L80. Inspect the shaft surface and surrounding sealing area for wear, scoring, or contamination before installing the new seal. Clean the bore and mating surfaces thoroughly so the replacement seal seats correctly.
