Alright i've just about had it with this! My truck when I go to drive starts up fine. Everything works fine. Once you drive it it wont shift gears until you let up on the throttle and not just when your foot leaves the throttle either. I would say about 15 second pause in between the throttle lifting up and the truck shifting. It is through every shift point on the powerband. When I go to WOT it throws the RPMs deep into the 6's and wont let up at all. HORRIBLE! I took out my chip thinking that was it. NOPE! I let the truck sit for about 25 min without the chip in it with the battery out. What happens SAME EXACT CRAP that happened when the chip was in. I have the JL Lower Pulley Installed as well as the ram air kit right now. The Diablochip has been uninstalled and is awaiting pickup from the postman to send back to JL. I just want to know if anyone has had this happen before? What do you think is busted? What caused this to happen? What can I do to fix it?

HELP!

Well, maybe you aren't going out to the speedway next weekend I don't really have any idea about this one, but on one of your other threads, 11SECL posted this info:
Hope thats not it!

Check the PCM and see if you bent any of the pins where you attach the harness with the 11mm bolt thats behind the battery. That could have something to do with it.

Look at the ID code on the side of the tranny. Is this a J1 or a 5X. IF it's a J1 it sounds like the mecahnical diode might have let loose. If it's not a J1, I'd have to go with the PCM is damaged.

Hope this helps,
