transmission types & t/c adapters (1980-86)
spline output shaft. We do not offer any adapters that
couple to this output shaft because of its length. If you have
this SM465 version, you can change the output shaft to the
10 or 35 spline output. We offer adapter two kits each for both
the 10 & 35 spline SM465 transmissions. The adapters for
these kits are either 3.50” or 7.00” long and are supplied with
the proper gaskets and bolting hardware. Both of the 3.50” kits
are supplied with a new Dana 300 input shaft. The longer kits
are a spud shaft design. The kits for the 35 spline transmission
requires the main output shaft to be modified. The threaded
portion of this output shaft must be removed to fit our kits. The
short style adapters will require some assembly work to be done
to the transfer case.

T18 Truck 4SP: This transmission, found in 1965 to 1985 Ford
pickups, is identified by a case length of 11.875”. The 1st gear ratio
is 6.32:1; 2nd 3.09:1; 3rd 1.69:1, and a 1:1 4th gear ratio. The
adapters we manufacture for this transmission come with a new
main shaft. This will usually allow the overall length of this
transmission to remain ideal for most short wheel based vehicles. Ford was
not the only manufacturer who used the T18 transmission. When searching
for a T18 in salvage yards, make sure the bellhousing bolt pattern has a
dimension of approximately 8-1/2” across the top, and 6-1/4” top-to-bottom.
The input shaft stickout should be approximately 6-1/2”. It is easier to adapt
to the Ford T18 than to the Jeep or Scout T18. We do,
however, also offer adapters for the Jeep & Scout trans-
missions. These kits are all a main shaft style kit. The
top end of the transmission must be rebuilt with the new
main shaft included in the kit. All of the kits include a new
3.25” thick adapter plate that couples the transmission to
the Dana 300 transfer case. The transmission bolt pat-
terns between the Ford and Jeep transmission cases are
different, so we do offer two different kits for that reason. This
transmission is also very popular for use as a transmission
retrofit when retaining the stock Jeep engine. For more
information see the 1980-86 Jeep Retrofit section of this manual.
