TH350/700-R4 to TH400 Convert Kit
Maximizer™ Conversion Kits
TCI® offers many different types of conversion kits to owners of General Motors vehicles to enable interchange of various styles of GM transmissions. This is particularly useful for heavy load vehicles that may benefit from a heavier duty transmission for dependability. All kits provide the necessary adapter plate, output shaft and hardware required for installation. The TCI 329900 kit also contains dust cover, dipstick and detent cable. Kits will require some degree of drive line modifications.
