Are you sure its coming out of overdrive or is the converter not locking or unlocking?

Have viewed what the computer is telling the trans to do with a scan tool? Also have you had a tuning done? Might be a couple of things to look at. Vince

I would think that your OD is no bueno, but it could be a stall issue. You do have a cooler on the car correct?

If you just installed the tranny cooler then my money is on something is burnt up in the tranny. Heat is the number one enemy of transmissions.

I am betting on engine missfire causing the PCM to disable lockup
