TCase

[bcrosson92]

so my tcase blew up. there's a hole in it the size of a tennis ball. i already had one laying around from a 98 zj that i was rebuilding. i swapped it in got everything put back together. now when i move the shiftier on the tcase it wont shift. the linkage moves and the case shifted on the bench before i swapped it in. also since the swap i cant put it in drive or any gear. the transmission snifter moves but i cant move the jeep. that must be because of the tcase issue? the tcase shiftier does not clunk into gear.

after reading it looks like the input from my jeep is a 21 spline and the input on the zj is 23 spline. is this correct?

That would be correct. You can change the inputs out, but you need to tear the case all the way down to get it out.

great i spent all day yesterday swapping it in in 26 degrees and snowing just to pull it back out and swap the inputs. is there any trick to make pulling it out any easier?

[4.3LXJ]

I always drop the cross member down. Makes it easier to get to the top bolts. But in the cold, might be six of one half dozen of the other

[bcrosson92]

i have been dropping the cross member there is a bolt right under the transmission rubber mount. but other then that no tricks?

Cannot think of any

[bcrosson92]

ok i might be able to use my sisters garage to do it so im not out in the open

Weather sucks eh?

[bcrosson92]

yep. there's like six inches of snow so thats not too bad but it was like 26 out yesterday and i literally spent 12 hours on putting the new one in and now gotta take it back out.

Well, back in the day I never seemed to swap engines unless there was snow on the ground

[bcrosson92]
