GM TH350 3 SPEED AUTOMATIC:
The General Motors TH350 has a case length of 21-1/2", 13 bolts for holding the oil pan in position and is available in two
different engine to transmission bolt patterns. The case is available with a Chevy bolt pattern that has the top two holes
8-1/4" apart or in a Buick bolt pattern that have the top two holes 7" apart. The rear side of the transmission case should
have a square bolt pattern that uses 4 bolts. There are several various lengths of output shafts that these transmissions
have been furnished with and you must make sure the proper shaft has been installed into the transmission for use with
the our transfer case kit. All TH350 output shafts will have 27 splines. The speedometer gear is normally located in the
tailhousing, but when adapting it to the transfer case, the location will change to the back side of the transfer case. The
rear transmission support is located in the main case just forward of the tailhousing connection. This can be used for
supporting the crossmember on some installations, but most of our kits provide support on the new adapter housing.
You must install the new output shaft we have supplied. This requires internal disassembly of your transmission, which
should be completed by an experienced technician. When installing the new transfer case adapter, make sure that the
transfer case coupler and output shaft do not bottom out. DO NOT FORCE THE NEW TAILHOUSING ONTO THE
TRANSMISSION. If assistance is needed, please feel free to call the number listed above.
When assembling the adapter housing to the transmission case, we have provided you with a new square-type "O"-ring
seal to prevent fluid leakage. This seal is a stock GM item that is used on all TH350 installations.
If you have selected a transmission that has the old style modulator then we recommend the use of the Advance Adapters
adjustable modulator, Part No. 716010. This will also allow for additional driveshaft clearance.
All installations will require the use of a transmission cooler. The cooler can be either installed in the radiator or a remote
location is acceptable. The transmission shift control can either be a Hurst floor mounted type shifter or sometimes the
existing column shift can be modified on certain applications.
