Tcase Removal

[HarryChest]

So I was finishing up my MT swap when I realized (from another post) that I have to use the Tcase out of my 95 for my speedo to work. The Tcase that came mated with the MT is out of a 91, so no go. I got the Tcase off the 95 auto tranny in about 20 minutes. I tried to remove the MT Tcase while under the truck and there was just no way I could seperate it from the tranny. So I just went ahead and pulled the tranny+tcase back out. Is there any trick to breaking the seal between the Tcase and tranny? I wrapped a tow strap around the tcase, stood the tranny up and tried to lift the tcase off the tranny with my engine crane and it just wont budge, the whole setup just lifted into the air. Any ideas?

I did the exact MT swap into my '90. You can probably see some of the goop they used to seal the tranny to the transfer case, and you think "ohh, that can't be stuck on there that well." WRONG! I think i used a prybar and a couple blocks of wood and pried against the various ears that bolts go through. I also remember destroying a fairly heavy rubber mallet in the process somewhere. Just make sure you don't beat on it too much of an angle, you don't want to take the chance of breaking something in the tranny. Don't worry, it'll come off eventually.

make sure you get all the bolts out, and put a pry bar on it. I've had mine off a few times and it was no drama at all.

Here is a trick I have used to seperate cases that you don't want to go gorilla on.

 

Get a pack of the old fashioned single edged razor blades and a small hammer/wrench/etc for tapping. Clean the seam, align the razor blade carefully and tap it into the seam. Leave it there and tap another one in 2-4 inches away. Do this until the mini wedges split the case apart. It has always worked for me...

Dito.

 

The pry bar is really the best way to do it.

You don't need to swap the whole case, just the speed sensor right?

I would like to know if you can just swap out the speed sensor to go back to mech from elec. I bought a 93 and the PO had swapped either the trans & transfer case or just the TC(maybe - I haven't looked at the #'s) what I have now is a Mech speedo and an elec sensor. I tailed somebody into town at 45, 55, etc. so now I just go off of the tach. would be nice for mileage tho
