I pulled out the Pontiac Service Manual last night and there is actually a section in there about TCC shudder. It said if the shudder occured AFTER it had shifted into TCC, the problem was probably not a transaxle problem and to check plugs, wires, coils and about 10 other things.

Does anyone know if the TCC solenoid is easily accessible from the outside of the transaxle?

I had an 82 Cutlass that had a bad TCC solenoid and it would actually lock the front wheels on the car when it shifted into TCC and you came to an immediate stop. Is there a plug somewhere on the transaxle that I can unplug to see if the problem goes away?

I'm pretty sure I felt the shudder when I had the car in "D" so I'm starting to think this might not be a good sign, unless it is an electrical (ignition) problem. Probably won't get to fiddle with it until tomorrow night either. Wanted to drive this car on a long trip next month and now I'm a little worried.....

Have you checked your motor and trans mounts?

The TCC solenoid is inside the transmission.

No, have not checked the mounts. I know the one by the water pump is good for sure due to my adventures getting that changed.

I did read in the service manual that it would set a code (39) but not turn on the service engine light, so that'* another thing I need to check.

Just seems like every week it'* something else with this car now and my parents kept it in excellent condition and always had the service work done at the dealer when it needed it.

What RPM are you at? is it variable? I haven't looked at what else you have done, but I would look at something simple like fuel filter, pressure regulator, and clean TB.

Won't get to really look at until this afternoon. It seemed to do it mostly at highway speed when going up a slight incline and the tranny (as far as I can tell) is still in TC lockup and it did not downshift was when it did it the most. I think it did it as well a couple of times when I had the shifter in "D" and not in "OD" which would then use the TCC function (I believe). So if it IS doing it when it'* in "D", I've got to assume that it'* not the TCC. Will check the plugs, wires and coil packs this afternoon as well.

thumbup2 PROBLEM SOLVED thumbup2 Stopped at NAPA on the way home and picked up a set of plugs, plug wires and a fuel filter. Installed plugs and wires and what I found was the #6 plug wire metal connector (not the heat shield) was not snapped on to the end of the plug. Checked coil packs and all were 5.91 ohms on the secondary side (post to post).

Took it for a test drive and the TCC is working fine as described in the posts above. No more shudder.

Got home and started checking the plug wires. First three all had good numbers. Fourth wire.....ZERO resistance (plug wire #4), fifth wire good, sixth wire was zero to 8.3 to 12.67 to zero (#6). Two bad wires. Guess they were just good enough to let the car run but once they got a load on them they started to misfire.

See pictures of wires below. On the coil end you can see the gray outer jacket and the white inner jacket, on the plug ends gray outer jacket, charcoal inner jacket. Burnt.

Second picture is of a good wire and you can see both ends are white on the inner jacket.

Oh...those spark plugs I figure are about 6 years old or older. I've driven the car for about a year and it sat for 5 in my driveway with occasional starts.

Not sure pics are on here.......might need some help posting them.
