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 hat 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
Advance Adapter 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.
When installing the new transfer case adapter, make sure that the coupler and the output shaft do not bottom out. We have
found on occasion that a transmission output shaft may be slightly longer than we have allowed for; and when coupling
into our new spud shaft, we find a small amount of interference. The adapter housing and spud shaft must be assembled
to the back of the transmission without interference. DO NOT FORCE THE NEW TAILHOUSING ONTO THE
TRANSMISSION. If assistance is needed, please feel free to dial 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 P/N 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.
