Transmission replacement on jack stands?

[John Higgins]

’ve been having some issues with the transmission on my 2011 LR4 (147k miles). Started after hauling a heavy trailer for a day.
I have some rpm hunting across different gears as well as some shudder. Did a fluid change along with a full valve body service (sonnax kit, new solenoids, reset adaptations) with no change.
I’m considering putting a used tranny in there and doing it on quickjacks. Anyone done it?

I was on jack stands, it is doable. Nice thing about jack stands is you can get in from the side. A lot of the stuff that gets disconnected for this job is supposed to be put back in with new hardware. Torque converter, front and rear drive shaft. Depending on mileage you may want to replace the drive shafts.

The transfer case is probably half the weight of the whole assembly. Keep that in mind when messing around with the transmission jack.

If you think you're due for coolant pipe replacement, do the rear at this time. So much easier getting to the bolts on the top of the bell housing from above and having that pipe out of the way helps a lot.

Thanks. Great info! Just did the rear crossover unfortunately

I haven't done it on an LR4, but I have on previous vehicles and it should be doable on your back. You'll want to rent a transmission lift and ideally a helper to see both sides when removing and installing.

Thanks for the feedback.
Before going the junkyard route; I decided to try some 'clutch in a can' anti shudder magic go-go juice and it's resolved my issues (for now).
I'll keep driving it for now and see what my options are down the line. Thanks all.
