:( Re installation of Transmission and transfercase
hey everyone im doing a 4x4 swap, and The only rhing left to do is install the new trans with case, already replaced front, rear axles, linkage etc. I cannot for the life of me re install the transmission. I have no way of moving to go buy a transmission jack, as the jeep is my only way of transportation.. i only have a 4ton floor jack and i connot get it to balance. I have literally been trying for hours trying to rig ways to tie the trans to the jack... no success... Can anyone give me tips or ideas on going about this??? |
How did you get the old one out?
|
With the 4ton jack. I pretty much just wifgled it out and as soon as it let go i let the fllor jack drop.. i was thinking the same thing, that it’d go in the same way it came out, but thats not the case. |
You could take some tie-down straps if you have them (or rope if nothing else) and loop it around the bottom of the tranny/x-fer and through the doors to provide a sort of hammock for the assembly, then use the floor jack to raise a little, tighten the straps, raise a little, tighten the straps until it's about where it should be. That would help to balance the weight.
The other option is separate the tranny and x-fer case. The big problem with the pair is that the transfer case is off-center weight so it has a tendency to tip towards the drivers side. Then install the transmission (it should be easier to keep balanced) and then the transfer case. The transfer case only weighs like 70 lbs so some folks just lift it by hand. If I weren't 1000 miles away I'd bring you my transmission jack. :) Edit - is it an auto or manual? Edit2 - If you go the strap route, get it as close to the engine as you can so you only have to go forward a little bit once it's at the right height. You may find that lining it up to mate with the engine is a pain (it can be on a stick shift since you have to get the input shaft through the clutch disc and into the pilot bearing, I don't know if there's anything similar for automatics or not.) |
Thats a good idea, i might just have to take off the transfercase, also it is an automatic. And i wish you could lol. Thanks for the tips |
Anytime brother - Good luck!

Take the t-case off. Its much easier. I put my trans in with just a jack. It wasnt fun or safe but it did the job. A second set of hands is always nice too.
|
I've done plenty of trans with just a floor jack and a 12"x12" piece of plywood. Wood on jack head, slide trans pan onto wood, grab tail shift pull down to balance and pump jack with other hand. I do this under vehicle blocked up. Lined up closest to where I wanna raise it up so I don't have to roll jack too far to line up pins. I also thread wire or twine through bell housing holes to keep torque converter from slipping out when I tip it up to slide on jack/plywood.
An extra set of hand to get it on jack is helpful but doable by one person. |
build a custom "cradle", using scrap timber & wire
it is possible to use levers and blocks to lift it up, corner by corner (onto jacks) I have done all manner of things this way, including truck gearboxes only having one jack is a severe limitation, 2 is better, 4 rolling floor jacks is heaven |
Thanks for the help and suggestions everyone, its nice to know there are nice people who still make an effort to help!! I really appreciate it! i actually took off the round top plate on my jack exposing the flat base, and positioned the transmission right at the flex plate, I then pumped up the jack as high as it would go and ran some straps like PatHenery suggested. I ran them left to right postitioning them in the front and rear of the transmission, i used the holes on the frame as the strapping points. I then lowered the transmission on the straps and slid the jack in perpendicular to the transmission, after that all i had to do was push the jack forward, move it up and down a few times and was able to go in incident free! https://cimg8.ibsrv.net/gimg/www.che...1198d9e96.jpeg |
Glad you got it in. I would highly suggest you get that thing back on the ground before those bricks explode. Bricks are not to be used as jack stands!

Hahaha - Thanks guys!
I can't take credit for the hammock solution - I read about that somewhere and thought it was a neat idea. |
