Computer threw three codes:

P0753 - Shift Solenoid A Circuit
P0758 - Shift Solenoid B Circuit
P1864 - Manufacturer Controlled Transmission

Trannyman:

Thanks very much for the response.

Warmed the car up to normal operating temp. No change in behavior. In D, the car can get moving, but it feels like the torque converter is behaving like a 4000 RPM race converter that never does lock up. In 1st, it pulls a little better, but nowhere like normal. Starts in 2, 3 and D are pretty much the same. Lots of RPM and not much acceleration.

Just for the hell of it, I tried clearing all the codes. The first two stayed off but the third code (the seemingly most vague of the three) threw again.

No shuddering, no noises. Still pulls in reverse just fine.

Any idea where to start?

Thanks...Boatman
