Description
The B&M Transpak is an advanced shift kit designed for 1968-1981 GM TH350 automatic transmissions. Building upon the features of the Shift Improver Kit, it offers additional manual control, allowing downshifts at any speed and the ability to hold first gear as desired. This is particularly beneficial for modified engines, towing, or heavy loads. The kit provides two stages: Stage 1 (Heavy Duty) delivers firmer shifts without harshness, enhancing performance and transmission life while maintaining comfort. Stage 2 (Hi-Performance) offers quicker shifts, retaining full automatic features and standard shift points in Drive. Note: This kit does not fit GM TH350C transmissions.
