Sounds like a mechanical issue to me, however for the time being i would just have it shift into 4th at a higher speed to keep the revs up. OR you can just change the TQ converter lock-up to 5mph higher than it is.

I would check your plugs, could be your problem :dunno:

Thanks guys, I changed the plugs today with no change in trans function. I will have to make those changes in hpt and check that site out. Heading to the track to try and hit a 12.9 or lower. Thanks, andy c.
