Transmission Removal procedure?

Transmission Removal procedure?
After 7 years and my small leak becoming bigger in the front pump seal i presume. it now just drips out like is making red coffee, im thinking of attempting to remove the trans myself.
Also today she decided she doesn't want to shift into 3rd, im pretty annoyed after i just put everything back together after my main fan exploding last week.
have any of you guys removed the trans with the engine still in the car? i cant find any info on it. and how hard or easy etc..
Looks like i might need to take it to a trans shop now for the 3rd gear prob.

Fairly routine RWD type of removal but it's a big job
A brief, over-simplified run down from memory......
-drain trans
-devise some sort of engine support
-disconnect left and right exhuast pipes
-remove starter (or at least the bolts)
-disconnect shift linkage
-disconnect trans wiring
-disconnect driveshaft
-remove trans mount
-remove flywheel-to-convertor bolts
-remove engine-to-flywheel bolts
-remove trans (200? pounds)
I'd hate to do this job on my back with the car on jackstands. But it's doable.
Cheers

Yeah, thought dealer was tough and that was 10 yrs. ago. Dealer bankrupt now and foreclosed on. Shawn: Car has to be high enough to get under + 6" for bellhousing clearance. Long (longer) extensions and flex the tranny up and down (watch rad fan) jack is essential (too heavy for one person, used Harbor Freight tranny jack with 3 ton jack) if you can get help get it. Fluid lines need undone and capped(drain tranny first). Use a engine holder on engine before removing tranny. I have been doing Jag repair (at that time for 30yrs.) so nothing was new to me. Soak exhaust pipes and slightly tap til free or cut and replace ($30). DO NOT TRY THIS IF YOU HAVE NEVER DONE A TRANNY REMOVAL BEFORE. USE JACK STANDS HEAVY ENOUGH FOR JOB AND PUT CHOCKS ON FRONT AND REAR OF BACK WHEELS. Might have to lift rear a bit to slide out tranny. HELP IS A MUST!!!

well yesterday a started to remove the trans. Larry how In the world did u get it out in an hour?
I tilted back the engine idk if it is far enough I have noticed the exhaust manifold where the first cat is located seems to be hitting the subframe mount. I seem to be at my length as to how far I can tilt the engine.
also when I unbolted the driveshaft fluid leaked out.???
turns out the bolt inside the tail shaft was just hanging in there not even screwed in. what a suprise.
this is a big task.
I'm still trying to figure out how to get to all the housing bolts.

Been a Jag mechanic since 1964 and worked in a shop during the 80s and 90s. Lots of extortion by mechanic and lots of extentions (3/8) and just know how. Might take off oil sender at top anything in way. Do not know how long the first one took. But remember we did all trannys in XJs and XJSs out in an hour. On lift, we used 3 people to lift tranny out without jack. If you can feel bolts with fingers they are reachable. Did you try taking top bolts out from top? Drain tranny first, does make it lighter and less messy.

Yep, dealer says 8+ hrs. But a flat rate tech/mechanic will do it in a lot less time. I had one guy working a stall over from me and he would leave lock washers out to make time. Shawn great job, goes in exactly the way you took it out. Make sure converter is locked in place, use a piece or 1/4" X 1" X 4" steel bolted on housing mount hole to hold converter in place, remove before last shove.

I've thought about whether putting the original transmission back in is the best choice considering that there are a few more modern GM trannys that could be made to work. A four speed would be a nice addition.
Seen it done once, right?
