Tranny swap

Would the transmission from my 95 gc laredo V8 fit in my 96 gc limited V8? Also if so how hard is the swap? Ive done a lot to different motors and the all around vehicles, but not much to any transmissions. I am by no means a mechanics but I'm pretty hand with a set of tools.

Took 7 hours to do a tranny and tcase swap last night,.

Diffculty: hard.

It is extremely heavy and mine was covered in mud, just to make sure your driveshafts will fit and the tcase will fit on the tranny too, 95-98 is usually a cluster of same designs so you should be safe,

Steps: Front & Rear Shafts, then Cross Member, then tranny mount, then you must remove the tcase shifting bracket from inside the driver side carpet under the center console near the shifter I had to slice a 4x4 sqaure to reach them, then you will unplug all plugs , then you will(or I had to) remove the exhaust by the two bolts by the intake and unconnect the O2 sensor plug, then lower the rear end of the tranny, then you will disconnect the tranny lines, then you will remove the starter to get to the flywheel, then you will start taking off the flywheel/torque converter bolts, you will need to manually crank the fan to move the torque converter, then you start taking off the belhousing bolts, make sure your dipstick is removed and the dipstick tubed is unbolted, and on your last bolt put a jack on the front of the tranny and when all done lower together, lower slow to make sure it doesnt tip and there is nothing still connecting. Repeat the process backwards.

if i missed something, double read. thats just how I did mine.

Ok why won't they fit, other than its a different tranny :-) Will it not accept it? Or it physically will not fit?

It will "fit", it is 5.5"longer though. It will not function correctly as the 95 is mostly hydraulic and the 96 is electronic control

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

I see. What about transfer cases and the motors? They're both 5.2 V8s and 249s?

Case is different(input length, there's a huge thread on this already), motor would require swapping most sensors, the passenger exhaust manifold and intake manifold.

Quite a bit will swap with some modifications where needed...what exactly are you after?

I have a 95 that the front end is totaled so I bought a 96 for $900. The t case is bad and the tranny will go eventually (314000 miles on the tranny). Do I was just wondering what I could swap out if the old one now that its getting s little warmer.

Transfer case should swap. sticky at the top. 249 to 249 will be fine.

Ok. I was also told that the 242s are pretty easy to rebuild and I plan on doing that swap when I can afford it. Would it be smarter to just wait until the summer to do that swap or swap 249-249 until then?

T cases will have different input lengths.

And the early version is less desirable anyways.

The rest isn't useful to you.

I am confident that the 249-249 will just swap, no rebuild or input swap. If you do this then you can tear down the broken 249 and pull the input, which should be the new style gear cut. You will then need to find a 242 or 231 that is 95 or newer (think a 6-94 T-case will have the new cut) but dont take the chance, 95 will be for sure. All I have read says you can not mix the new and old cut.
