And make sure you check the small drain hole from the servo on the right side. If you look at pan and gasket there is a notch cut out for it. If sealer has ever been used it could be stopped up. Wipe the bottom of transmission pan gasket are clean and transmission pan and put a good cork gasket on dry.

Re: bad torque converter symptoms
Should I try this? And if so, which pin grounds the TCC? Thanks.

Re: bad torque converter symptoms
Grounding ALDL pin 'F' will only work if the connection at the transmisison is intact. Also, it will only function if the auxilliary contacts on the brake pedal switch are closed, and there is 12VDC present on the purple wire at the switch. Grounding this pin will operate the TCC solenoid valve completely independent of the ECM, so any other possible parametric causes for the TCC to remain open will not be an issue. You need to be sure the vehicle is either in motion or that the vehicle is raised and secured with all drive wheels off the ground. |

Re: bad torque converter symptoms
Let me make sure I've got this right. I ground the "F" pin, while driving at a consistent speed? Something like 45mph? And if I dont feel a drop in RPMs, TCC kick in, then theres some serious shit wrong?

Re: bad torque converter symptoms
I havent been driving it much at all lately, tihnking about just selling it. It's too damn cold to mess with it right now, -20 with windchill. But surprisingly it starts like a champ, I let it run for awhile since its so cold.

Can I by monitoring the F-pin see if PCM is trying to lock up the TCC? Fom what I read here I figure the wiring should be something like: +12v----[break switch]-----[TCC solenoid]----[F-pin]----[PCM]---Ground Just curious. /Freddy |

Between 50-65 steady speed no pull or uphill converter should be lock in and stay locked in when let up on gas a little. This post is old and should be dead. Best to start our own new post on your problem. I would get a computer read out and code check on engine and transmission. Best to start your own post on this.

Re: bad torque converter symptoms
this is old and also not a torque converter issue. check engine with scanner , check fuel trims also TPS check. IAC TB cleaning recommended.
