86 GP 200-4R tranny question
My GP with the 305 is acting a little funny upon stopping and starting as if the tranny is not downshifting correct. It is like when you come to a stop it acts as if it has a manual tranny and is about to stall. Upon starting then it kind of luggs as a manual would starting in a higher gear. I am going to change what is called a "transmission control solenoid" from Auto Zone. That is the only solenolid listed for the tranny. I don't have a lot of tranny experience and wondered if you folks thought I was on the right track and exactly where this part is located on the tranny and if it is internal is it easy to change? Thanks

You are correct. It sounds like you need a TCC (torque converter clutch) solenoid. It is a very common problem.
Drop the pan, remove the filter, unplug the connector, remove the 2 10 mm bolts and pull the solenoid out of the pump. It's real easy. There is a tension spring under the filter, pushing the filter down. Make sure that you keep it UNDER the filter when you put the new filter in it!

Unplug the connector and see if the problem goes away when you go for a short drive. If it does then it is electrical.

Not necessarily. A restricted TCC solenoid may only act up when warm, so unplugging it may not really prove anything.

I searched long and hard until I found the problem on a GN board. And it is easy to replace.

Thanks folks the problem is solved. This solenoid has been bad longer than I thought because the car runs as new now. My Gp has been sluggish for a long time and I thought maybe the engine was just getting tired. Not until it got to the point where it felt like a manual tranny ready to stall upon stopping did I know I had a problem with the tranny. She hasn't felt this good in years.
I have a pneumatic pump(sucker) that I used to suck out the tranny fluid through the dipstick tube. I highly recommend it.

Well since fixing my problem with the solenoid I have now developed a leak not from the pan but up front between the dust cover and the oil pan. It would almost have to be the front seal but I cannot see why my repair would have anything to do with that. I also find it hard to believe it just happend to begin leaking on it's own the day after I did the repair. Also I did not over fill the fluid. Am I missing something? The last thing I want to do is go the the trouble of replacing the front seal.

It does sound like the front seal has failed, may have already been that way and you didn't realize it, and now that the lockup is working, it makes for more pressure into the converter possibly, as I am not certain how the lockup works, only that it engages the converter housing.
