t-4 or t-5 ?

[firefly]

I was given a Transmission . the guy told me it was from an AMC. There's no tailshaft. It's got 13-51-097-901 on the case.There is no shifter on it and I can't tell if it seems to be a 4 or 5 speed.How can I tell? Thanks

T-4 is a 4 speed
T-5 is a 5 speed
try shifting it over by reverse and see if there is also a 5th
Does it have a stub of a shifter? Most of the shifter is removable except for a stub. It might be hard to shift with the stub. The t4 and t5 use the same case. It would be very hard to tell the difference without shifting it or opening it. Look for an identification tag.

Edit: Here's what the shift lever looks like on a t5. If the stub is still on theT5 can you shift it with a pipe or square steel bar?

I looked at the varients page here. I must have missed something,the T-4 and T-5 look identical.

I tried shifting it with the stub. I would like to think there is a better way besides opening it up,I'll try again and count revolutions at the tail I guess.

the T-4 and T-5 are basically identical on the outside. Those casting numbers are for a T5.

the t-4 and t-5 look identical.

They are exactly the same. The are made with the same case. Inside that case they may put 4 forward gears or 5. I wish I had an easy way to tell them apart but it don't.
Is there a tag under one of the bolts?

CJKrawler is right those casing numbers are for a T-5
I googled them
You have a 5 speed

Count the splines on the shaft, I think it sb 10 if you want to use it, if its 14 spline you will need a new clutch kit or at least disk. I'm too lazy to look up what size the disk is or the year you have, but I'm sure you can google.

Wait a minute. You have a '74 CJ5 and you were given a T-5 Transmission ? That wont work unless you also have the Dana 300 Transfer Case that came with the T5.
You aren't planning on putting that T5 into your CJ5, are you? Your '74 has a Dana 20 transfer case. The Dana 20 expects to be mated up to a transmission that has a big gear sticking out the back of the tranny on the output shaft.
The Dana 20 expects the output shaft of the tranny to fit into the TCase. It's a much different setup. Not compatible.

No,I've got a t-18a to put in the cj.This T-4 or 5 was lying on his garage floor and he was going to scrap it. I thought I could maybe get him a few bucks for it. If I knew what it was.

 

[BusaDave9]

Oh, I see.
T-5 very bad
T-18 very good

CJKrawler got it right. You have a T5
