The solenoid connector repair harness has shipped and should be here in a few days. On the way home tonight, I was going up a hill and not really giving it much throttle has I had built up some speed before the hill. About half way up, the light started flashing. The trans had not downshifted, no change in rpm's on the tach that I noticed, no shudder. I know the TCM has already detected and stored other "events" in order to set off the light at this time, and this was the last event needed to make the "quota" and trigger the light. I just find it odd that the TCM will detect a slip in this situation when I am not giving a lot of throttle as opposed to not detecting a slip when I have the throttle wide open pulling a hill. I am just thinking more and more that the torque converter is the culprit and is just starting to fail, since there is not chatter or shudder. You guys already know the question I am going to ask if my testing shows the TCCS to be fine: What TC would you guys recommend to balance cost with reasonably robust operation? I only very rarely tow something heavy (like a bobcat maybe once a year) and for only short distances, and only haul loads in the truck sporadically (loads of topsoil, firewood, lumber, etc.). Usually the truck just runs empty back and forth to work. I can't see spending $800 or more on a TC for that type of use, but around $400 - 500 could be doable.
It don't need to have a heavy foot to make the tranny slip. It can slip with a steady foot on the go peddle Slip is detected by speed and RPM. When they are out of spec you will get a slip code.
The converter can slip without shudder. Shudder comes when the clutch material is very much gone.
Even if you don't tow heavy I always recommend going with a multi disk billet cover converter. Billet to prevent warping. Multi disk to increase clutch surface.
Also change out the converter regulator spring. This will increase clamping force and lesson the chance of slipping.
