Obviously talking automatic transmission here... trying to figure something out, need some auto trans experts to tell me if I am thinking correctly here.
I think I may have fried my torque converter clutch.
It was my understanding that a torque converter clutch should only lockup under cruise conditions. However I read something that indicated it will lockup under part throttle conditions as well. Can someone confirm that? If that is the case, I know I need to check my trans fluid for metal, and if I find metal in it, I'll know I most likely fried my torque converter clutch.
I still haven't figured out why the torque converter clutch would be attempting to lockup around 5000RPM in 3rd gear under WOT. It is my understanding that it should never try to lockup while under WOT. My only theory is that my PCM doesn't think it's at WOT when it really is. If the converter can lockup under part throttle, and it still thinks it's at part throttle, that is most likely the cause. I know that my PCM is supposed to see WOT as anything greater than 2V from the TPS. I am pretty sure it's close to 4V with the "pedal to the metal", however I'd have to go back and log it and look.
