The car in question is an 84 242 turbo with an M46 and 180K. I purchased the car within the last two weeks with out a working OD.

At the time I assumed that the problem was probably electrical, but after going over the relay, selanoid, and the 4th gear switch I found that all of the electrical components are ok. I then changed the fluid to Redline MTL and cleaned the lower filter under the OD inspection cover.

Currently the OD will engage at speeds above 60 mph and only upon removing my foot from the gas. As soon as the gas is reapplied the RPMs go back up into the range that they would be at w/out OD (about 3600 at 65 mph) If I apply the clutch and shift into od it does not seem to engage although the light is on.

Am I looking at a bad OD clutch? It seems that way since as soon as torque is applied the RPMs shoot up again, whereas if I don't apply gas the car will stay in overdrive.

How bad is it to rebuild an OD with the kit from IPD plus a new clutch? I printed out the instructions in the FAQ, but I'm a little unsure of myself.

Does anyone have an approximate price for this job if I took it to a shop to have it done?

Thanks
