Description

The TransGo 350-3 is a TH350 full manual transmission reprogramming kit designed for 1969 and later models. This kit allows for stick shift operation, making it suitable for competition, off-road, and pro-street applications. It easily converts back to automatic shifts and increases line pressure for firmer up-shifts.

Installation of this kit does not require transmission removal. However, it is not compatible with lockup transmissions.
