My tranny pops out of reverse, please help!

So, my 5spd on my '88 YJ just started popping out of reverse yesterday morning, and did it again this morning. Doesn't matter how easy I am on the clutch, goes "Bang" and pops out! What's the deal? It is the Puegot tranny, and I have 110K miles. Has not had ANY symptoms at all before this. Did not do it backing out of the carport either day, just at the gas station after gettting coffee about 2 miles down the road. Any ideas on what could be wrong?

Thanks in advance,

Mike

Check the skidplate and see if it is drooping any. Mine was doing the same thing a month ago and eventually wouldn't even go into reverse. Two bolts had rusted through the skidplate, which allowed the tranny to droop about 2 inches. Since the tranny is lower, the shifter is lower and won't allow the shifter to settle completely into gear, causing it to pop out occasionally.
Hope this helps.[img]/wwwthreads_images/icons/wink.gif[/img]

I have a 1.5\" lift kit on>>>>

that I put on a few months ago. It does drop the shifter and it almost hits the console in 2nd, 4th and reverse, but not enough to stop it from engaging completely. I will check to see if the xfer case and all has dropped some. Thanks,

Mike

Re: I have a 1.5\" lift kit on>>>>

do you have a body lift? this can cause problems with the shift lever hitting the floor of the tub. Also, it could be a synchronizer problem inside the tranny. My 5sp started to do it just before I put the auto and V8 in. good luck

Re: I have a 1.5\" lift kit on>>>>

All of your post did not get through. With a lift kit that requires the x-case drop or a body lift you will run into the problems you are experiencing. The proximity of the shift lever almost, but not quite touching the floor pan or console can be changed by the transmission mount failing and sagging. This allows the shift lever to touch or hit the floor pan just short of locking in gear. It will feel as it went in. But in fact did not. This is a very intermittent problem that will over time get worse and eventually cause gear failure. Pull the boot and check very carefully around the floor area when you drop it back in 2nd 4th, and especially reverse.[img]/wwwthreads_images/icons/smile.gif[/img]

now that you mention it, my tranny mount is>>>

broken. It did not seem to matter at first, but that may be the problem. It is the one on the left side that stops the drivline from torquing up under load. It is there, but is stripped and connot be tightened, in fact it causes jerkiness in the drivetrain if you hit the gas hard or let off it quickly, especially in lower geaqrs where more torque is going thru the drivetrain. Does Energy Suspension or anyone like that make a firmer, urethane bushing for this application? Even at the parts store they want like $85 for the mount!!!!!!! That seems awful high for a piece of rubber, a bolt and a few washers, and I would like a urathane piece that won't wear out like a mushy stock one.

Thanks again,

Mike
