TC Staying Locked
Maybe I'm crazy but just today it seems like my TC won't unlock (in D or 3), it's a yank 2600. I just personally flushed the tranny and everything was clean (TCC screens, etc..) no real material in the bottom of the pan, and I don't have any codes popping up.
The transmission shifts normal, it doesn't have any unusual up or down shifts, no slipping, and at WOT it seems fine (A/F and Boost levels are normal) but anything below 1/2 throttle is just seems like it doggin' on me.
Also say when I'm on the freeway doing 65, I'll give the engine a little burp to speed up a bit and the TC unlocks for a second, then locks back up.
Any Idea's or is this just normal and I'm finally realizing I need to up the boost
