1984-1992 GM 700R4/4L60 (Non-Electronic) 2-Wheel Drive, Automatic Shift Valve Body Traveler Transmissions are rugged models that have a medium firm shift compared to the harder shift of the Street Strip models. The Traveler transmissions are recommended for light trucks, RV, Towing and off-road applications for heavy duty use and feature an increase of oil flow compared to a stock transmission. This increased oil flow provides the necessary additional cooling to make these transmissions live longer when subjected to mile after mile of grueling abuse. B&M strongly recommends adding a Hi-Tek trans SuperCooler to help further reduce heat build-up and extend the life of all automatic transmissions. Does not fit Corvette, or 60 degree V6 engines. Does not replace 4L60E transmissions. Fits 1984-1992 GM 700R4/4L60 (Non-Electronic Shift Model) 2-Wheel Drive. For use with 30-spline torque converter. For use with 30-spline torque converter.
