Transmission removal tips please?

Removing my transmission tonight. It's roached and I got a new one on order. Should be here Tuesday. Was just going to do a YouTube search and search wrangler forum for directions. If anyone has any input or tips or stuff I should know that'd be awesome. I'm just going to dive right in. Any help would be appreciated.

I think your tools and equipment with make a world of difference with the transmission removal. If you don't have one or know someone who does, rent a transmission-attachment for a hydraulic floor jack. It's an adjustable / tilt-able plate that keeps the tranny snug in place safely with straps/chains. It makes it a heck of a lot easier when trying to get it to align back in place when you're putting the new one in too.

Or go to Harbor Freight and invest $80 on one of these. I use it for all kinds of stuff.

Transmission Jack - 450 Lb. Capacity

Hot tip remove the T-Case and trans separately makes it easier only a couple more bolts.

Get a clutch kit while you are in there if it hasn't been replaced lately

I've removed several jeep trannys. Agree with everyone. You need a decent trans or atv jack. Do not attempt with a regular floor jack. I just did that in an emergency and it was an enormous pain. Nearly gave up.

Also separate the trans and xfer case. It's 6 bolts and drops the weight by half.

Thanks guys. Tried it Friday night. Gave up after I couldn't get the skid plate off. Have it soaking with WD 40. Try again tommorow night. I was away all weekend or I think I'd have it by now.

wd 40 can get the job done sometimes but it is not a penetrant, you may have better luck with PB blaster

The new WD 40 is a penetrant. It works just as well as PB. Only know because its what I used on my last trans removal. But it has a different label than the standard stuff.

I don't even know what kind I have? It's got the funky space age nozzle on it tho. It's jointed or whatever. I broke 3 sockets lat time. But didn't strip the bolts. So that's a good sign I guess.

Any other tips for getting those bolts? I can't use heat because I don't want to damage brake lines etc. that are close to the skid plate on the frame.

Heat might be your only other option if you don't have access to air tools. Map is my preference. Have you just tried a sledge and a large breaker bar?

Well ive never taken a tranny skip off before but my general rule with rusted bolts is to spray with penetrant, wait a few hours at least, repeat, repeat ,repeat lol. I saw someone on hear recently mention 'dye penetrant' or 'die penetrant' i cant remember but he claimed it made pb blaster look like a toy so maybe check it out?

I'm a NDT Guru... (LOL) dye penetrant will wick into some of the tightest places. But to tell you the truth I'm not sure how much of a lubricant it is. I'd be willing to give it a try... but keep in mind, the stuff is very hard to clean out of the cracks on your hands!!!

Ok. Thanks guys. I'll try the impact and if that doesn't work I'll go try to find that dye stuff. Where do I get ahold of it? Auto part place?
