This kit is for the professional mechanic only. Itâs not for the do-it-yourselfer. It is designed to improve the shift performance and durability of the General Motors Turbo Hydra-Matic 350 automatic transmission by furnishing additional oil flow to areas of warp and wear and exhausting the cross leaks that often cause friction failure.
This kit fits the General Motors THM 350 non-lockup only! There are three transmissions that look alike. Be sure to identify your transmission before beginning installation of this kit.
