I have to replace the rear shifter bushings on my 80 931 and don't see any detailed info in my Haynes manual on the best way to do it. The archives mention that you can do it without pulling the tranny off, but this does not seem to be do able to me. Maybe if you changed them before, but can't see exactly what's what above the tranny there when its still in the car. Is the bushing replacement able to be done without dripping the whole transmission? If not, is there some info on what the procedure is to do this? Thanks in advance.

I have to replace these as well. Based on the info ive gathered you have 2 options. 1st is to drop tranny. 2nd is to cut access hole through sheet metal under rear seat bump. Ive seen a picture of cut out access hole and looks like a fairly easy deal but im still on the fence. ill try to find the pics again and give you the link. http://www.vaughanscott.com/construction.htm#TRANS HUMP ACCESS

Sounds interesting, but I wonder how easy it is to cut out the metal in that spot....sure would make it worlds easier to change the bushings if there was an opening there for sure. Anybody else do this mod successfully?

Dude, its right here:

Doing it in the car is possible, but I imagine that it isn't fun. You'll need a good ratcheting 13mm box end wrench to remove the pinch bolt and a punch to drive the coupler off the transmission. Then you'll need to disconnect the main shaft from the shifter to slide the shaft back far enough to drive the center pin out to remove the coupler and replace the bushings.

Doesn't sound too bad, huh? Imagine doing all of this without being able to see what you're doing and work at the same time since your hand will be in the way. Your arms hands will have to be up in the air the entire time, the exhaust and axles will be in the way, etc.

DONT CUT!!!!! Thats the hack way to do it. If you cut you have to watch out for brake lines. Its not worth it.

I did mine a couple yrs ago. It isnt too much work to drop the tranny, and if you've done it once it is really fast. Do it right and believe me you will love the difference once you are done. Its worth the work

Don't hack up your body. Dropping a snailshell is like falling out of a boat and hitting the water. Just do it right, it isn't difficult and it won't take long.

Plus, while you have the axles off, you can service your CV joints. This is an often neglected area that can lead to a fat bill down the road, and can actually leave you stranded in the event of CV failure.

I am not really keen with the idea of cutting my car up anyway, so I'll do it the right way, and considering it will probably not be the last time it has to be dropped I might as well get some practice in doing it. I did read the FAQ on it before, but there weren't any specifics on doing it so I guess it's a pretty straight forward procedure, just time consuming.
