232 amc/3speed needs a 4 speed....

any idea what a BOLT -IN 4 speed would be?
early T-10?
if so, what application?
(no granny 4 speeds,ok?)

 

AMC got their own version of the T-10, but I dont know if it's gonna fit the old 6 cyl stuff. But a good place to start might be finding something for a later Jeep 258, I think the engines are similar.

 

From what I recall (going back to the mid 80s here!)...you can use a four speed from a V8 Javelin/AMX or other AMC product of the late 60s/early 70s behind a 232/258 six. I only say this because a buddy back then (1987) bought the spare three speed manual trans I had for my 74 Gremlin 304 V8 car. He munched the four speed in his 70 AMX and just wanted a ****** to put in there "for now". He said six cylinder and V8 three speeds were the same, so it stands to reason that if my old three speed bolted into his car, then a four speed from one of them should fit behind a straight six...if indeed he was right about that six and eight transmission deal. (My trans was out of a V8 Hornet).

 

i have an amc t-10 4 speed. let me know if i can take some measurements for you. i won't be able to look at it until after dinner today.

 

You can use the T-10 out of any AMC car, but make sure you have the correct bellhousing...i believe the 3-spd bell is shorter ( 6in ) and the 4-spd is deeper (8in ).

AMC used the Borg-Warner T-10...it had a 1-1/8" 10 spline input shaft....the bellhousing bolt pattern is the same on all 232/258 and even the 4.0 jeep 6cly and 290 thru 401 v-8s. AMC also used torqueflite trans ( 904-998-727 ) but these had to have the AMC specific bellhousing bolt pattern. I just put a Jeep 4.0 (carbed not injected ) ina 73 Gremlin with a 998 torqueflite trans. My 2 cents... amcdv

 

hey bud my neighbor has a 304 gremlin with a top loader ford it bolted right up you will need a 1/2 inch shim for the throw out bearing

 

I used a Javelin T-10 4-speed in my 1974 6 cyl 232/258 Jeep for many years until I sold it.
I won't get into the transfer case details, just the engine-to-trans stuff.

The 6 cyl had different bellhousings available for it. Be sure you pick the right one.

What I did was to find a 1965 Rambler station wagon with the heavy duty 3 speed ****** (T-86 light duty V8 trans) and pirate the bellhousing.

Most 6 engines used the "normal" 6 cyl bellhousing, but if you find a "heavy duty" Rambler from 1965 and a few years later, with the T-86 ******, you will have a 6 cyl bellhousing that is a little deeper and made to hold a v8 trans.

The AMC T-10 is a lot like the Chevy T-10 or Muncie except that it has the Ford/AMC case-mounting pattern, a longer shaft, and a larger 3/4 inch pilot at the tip of the shaft.
Same splines and clutches as most Chevy and Stude.

The hard to find AMC T-10 will fit the AMC 6 cyls and the Studebakers without a lot of work, but if you want an easy-to-buy 4spd trans for the 232, you might prefer getting the Chevy Muncie and making your own pilot bushing for the end of the crank. The Chevy mounting bolts will likely stick out past the bellhousing surface, so a steel plate on the bellhousing may be in order.
We have done that before on Studes.

When you adapt a different trans, the most important things to watch are the centering of the trans to the crankshaft (very important), the depth of spline engagement in the clutch, the pilot bushing, the fit of the T/O bearing (sometimes a sleeve is needed), room for the T/O to move, and finding the right disc with the right splines (usually very easy).

That may sound like a lot, but it isn't as hard to do as it sounds.

Many of those home-brew swaps will fail because people get tired and cut corners. Mostly it is in the failure to align things just right, and the ****** wears out quickly or doesn't shift right.

Make sure you take the extra time to align everything just right.

If it were me, and if I couldn't find an AMC HD bellhousing, I would start with the Chevy version of the trans.
