I am going to buy an AMC bell pattern TC727 from a 4wd Jeep. My interest is using it as a back up for an AMC Javelin.

I understand that the tailshaft is different, and I've been told that the output shaft is different as well.

I know a little bit about my way around a TF/TC transmission, but what's involved in swapping out the output shaft?
I assume that replacing the tailshaft only involves unbolting the old, and bolting in the new.

Specialized tools required?
full transmission rebuild required?

Thanks,

Steve

My understanding is that the output shaft only comes out from the front. You have to pull the trans apart . I had a FREE Motorhome 727 with a fixed yoke and wanted to swap a few parts around. A local trans guy said that the front pump, valve body and everything has to come out. I gave up . I'd sure like to know if he was telling the truth. He liked to drink and sit in his underwear.

he was correct

I have a 727 MH short shaft with bolt on yoke as well

I moved the xmember forward 2" and used it in my 88-440 truck anyways

I will build a drive shaft with the slip yoke in it

done that on a sb 727 short shaft in a 68 Dart as well

just got to watch the tranz mount location,my 1 1/4 ton chassis 727 shorty was 5" from main case

the SB shorty was 7" from the main case like the rest of the 727 long tail shaft trannys

not a big deal if you dont mind the drive shaft build

do you still have it?

Thanks for the information guys. I passed on the purchase after seeing it.

I think I could have handled the swap, but I didn't realize the Jeep guys notched and hacked away at the case to suit their application.
Had a hole for the CPS sensor, had a hole for a relocated vent tube, etc.

I'll stick to the 2wd stuff for now on.
