Would some of you guys mind commenting about the results upon doing the APPS:

Things got better for you or didn't change anything at all or things got worse ?

 

I did it, and it seemed to be more responsive. I think it makes the biggest difference if you do it after different driving conditions. For example- If always city driving, do it before you go on an extended hwy trip and vice versa.

Seemed to be effective. Acceleration is smoother, no flat spot or hesitation at about half throttle. No improvements in MPG.

 

On mine it did improve shift points and therefore acceleration. Since I had some noise on the APPS signal to the PCM I installed a noise filter and had to recalibrate again.

After reading this thread, I went back and read the procedure again. It seems I left out a step. I didn't set the parking brake as prescribed. Will that make a difference?

As far as I know, it won't make any difference if you don't set the parking brake. I didn't set the PB when I performed this on my truck, however it still cured my tranny from occasionally dropping out of lock-up in overdrive at 65 mph. ;D The truck has not done it again since I did the reset.

 

OK...I did the reset last night and WOW...shifting and over all acceleration improved dramatically...Smooth...Smooth...Smooth

:P

 

Helped my shift points under full throttle was shifting at about 3200 after reset dropped me down closer to 3000. ;D
