I have a 2001 1500 4X4 offroad. I believe it has a 46re Trans. It seems like when it warms up the TCC quits locking up. I can kinda work the throttle and get out to go ahead and lock up but as soon as I let up, it unlocks and I have to jockey the throttle again to get it to lock. Any body got any idea why it's doing this? No trans trouble codes present. I do have a small evap leak code but I don't think that has anything to do with it.
