T15A (1972-75) - This 3 speed transmission can be identified by a case length of 10.000”. T15 or 1307 is normally cast on
the side of the case, and 8 bolts hold the shift cover to the top of the case. This is probably one of the strongest
of the 3 speed transmissions. We manufacture adapters to fit both Chevy & Ford blocks. The adapter length
is a 1-5/8”. The input shaft has an O.A.L. of 10-7/8”, and is a 1-1/8" 10 spline. There are a few transmissions
that may require the changing of the input shaft to work with our adapter. These applications would be in
trucks, wagons, and in some Jeep Universals. To verify this, simply compare the listings below to see if
your shaft will be compatible with our adapter kit.

T150 (1976-79) - This 3 speed transmission can be identified by a case length of 9.250", a casting number of 2603983 on
the case under the fill hole, and the top shifter mounted to the case with 8 bolts. The input shaft on this
transmission is a 1-1/16" 10 spline, and has a pilot tip diameter of .670". It was normally used with an AMC
304 V8 engine, so it is an excellent transmission for most V8 conversions. The T150 is very similar to a
Ford 3 speed transmission. We manufacture two types of GM adapters for this application.
When using a stock Chevy or Buick bellhousing, we offer an adapter plate, P/N 712527. This kit comes with a special pilot bushing
that is extended to allow support for the input shaft. This kit will also require the use of our clutch linkage bracket, P/N 716638.
In some cases, it may be necessary to shorten the extended pilot bushing to prevent interference with the clutch spline area. The
input spline engagement to the clutch disc is not always 100%.
An alternative would be to use our full bellhousing kit, P/N 712548. Using this bellhousing design will permit the use of all the
original clutch linkage. The advantages of using the full bellhousing kit include the use of a standard pilot bushing and full input
spline engagement to the clutch disc.
This transmission bolt pattern is the same as a standard Ford. A Ford bellhousing can be bolted directly to the T150. No adapter
is necessary.
