GM 4WD TH350 AUTO TO JEEP NP231
TRANSFER CASE (27-SPLINES) 1995 & UP
GM TH350 AUTOMATIC
The General Motors TH350 has a case length of 21-1/2", 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 has 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 the TH350 transmissions have been furnished with. This kit
is designed around the 4WD version having an approximate output shaft stickout of 1". The rear transmission support is
located in the main case just forward of the tailhousing connection. This can be used for supporting this 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 transfer case input sleeve 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 the transfer case, we find a small amount of interference. The adapter housing and 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 call us on our toll free number, 1-800 350-2223.
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 O-ring seal is a stock GM item that is used on all TH350 installations.
This adapter can be used on either Jeep Wranglers 1995 & newer or Jeep Cherokees 1995 & newer. The only difference
is the transfer case shifter linkage. The adapter is 1-1/2" thick and will provide an overall transmission assembly length
of 23". On this conversions, you can anticipate driveshaft modifications.
