I bought the superchips 1715 for my Ford F-150 supercrew 2003. Everything is cherry except for an occational jerky downshift then quick upshift. What happens is that while driving slow in traffic (approximately 5-10 mph), when I slightly press the accelerator, the truck jerks as if it can't make up it's mind on which gear it should be in. It is really pronounced and it only happens between 1st and 2nd gear when I'm driving slow in traffic and the truck has been warmed up. I have the truck tuned to performance. Do I have the right model 1715 for my truck? If so, should I set the shift point to stock for those gears? Also, should I set the shift pressure to stock for those same gears?

 

There's no such thing as a wrong model 1715.

Sounds like either you have an issue with your PCM code, or the pump in the tranny (warm is the indicator). Try playing around with the shift line pressure/points. If that doesn't solve it get the 4 digit PCM code from the passenger side door frame near the hinges and call Superchips with it.
