Transmission seal
It appears that I have a leak at the seal where the shifter rod enters the transmission on my '86 930. It resides under a rubber boot where the shift rod exits the tunnel. I cant find the seal in a parts diagram. Can anyone direct me. Also, is the replacement easy? The car is on a lift.

The seal is a pain to replace with the transmission in the car, but I have done this twice now.
To get it out you need a sharp object with a hook on it. I filed a screwdriver down and put a notch on one side. Working from inside the car...tap the screwdriver into the seal then pry it out (the seal is soft halfway between the inside and outside. When prying out make sure you do not scratch the transmission surface or the shift rod.
Putting the new one in is easy, clean the shift rod shaft, then oil it (motor oil or just light household oil) and lubricate the outer edge of the seal then slip it over the shaft and press the new seal in. I use a 2" long piece of plastic pipe over the shift rod which is the same size as the seal, tap the pipe against the seal, gently pressing it into place, check occasionally to make sure it is not distorting as it goes in.

One more thing, when you do this, raise the front of the car about 6 inches so the transmission is tipped back otherwise when you pull the seal some tranny fluid will leak out.

Where do you access it from inside the car. I don't see any problem with "picking" the seal out because with the car on a lift there is easy access.

If it's leaked before (like mine), smear some Curil T around the outside of the seal. It's very important to slide the seal all the way into the tranny (D has a good suggestion with the PVC - I used metal conduit cut to about 4 inches). Here's a tip to remove the old seal - sacrifice a $1.00, 8" ace hardware flat head screw driver by filing it down to (nearly) a point. Push the point into the left side of the installed seal and pry. Then go to the other side and pry. Repeat until its out. When I did this job two weeks ago, it took 20 min total.
