Is it hunting between lock and unlock or does it not lock at all? If it is hunting reset the apps and see if that helps.

I agree on resetting the APPS. I always say start with the easiest and cheapest first.

Unhook your batteries for atleast a half hour, hook them back up, turn your truck to the on position, slowly and steadily push your accelerator all the way down and back up. If there is anything I'm missing I'm sure someone else will be along soon to help out...:Thumbup:

Could be,bad lockup solenoid,boost valve problem(broken spring cover is common),bad convertor,or just a wiring/sensor problem.Your going to need a trans shop to do some pressure tests,and check the wiring out if your not mechanically inclined,and able to do them yourself.It is highly unlikely an APPS RESET is going to fix it. Im going to take a guess at a bad convertor seal,it happens now and again.

99% of the time if it's a wiring or sensor problem you won't have 1 and 2.

So you can pretty much rule that out. Check your gov pressure, it's really easy on your truck. It's a test port on the right side of your trany. If your gov pressure is too low, you got a easy/fun problem to fix.

Powerdemon is the maker!!! It has a 3 disk tq converter and the transmission has a 70,000 3 year warranty and the price $2,500 for a whole tranny..!!!!(Honestly I think the company is out of business).. But I fixed my issue.. I just unhooked the batteries for about an hour and it shifts fine now for about a week???? The tranny holds I have around 500 hp so I know it holds truck pulling and drag racing.. If it ever does go out I will be getting a Suncoast definitly!
