Red face Updated aggressive race file slip issues

Hey everybody, I recieved the updated aggressive race file from Matt last week and I have completed the two hundred mile relearn strategy and I am still experincing some 2-3 and 3-5 shift slipping. Only happens a couple of times a day and it's not too bad, only enough to notice. I sent Matt a PM, so I know he will figure it out asap. I just wanted to post this to see if anyone else is experiencing this problem. Maybe it will help Matt in diagnosis. I hope its not my tranny... oh well if it is. I have tried bumping up the shift pressure in the optional parameters, but it only took care of the 1-2 slight slip. What do you guys think I should do? Thanks for everybody's help.

Kyle

what does it feel like when it happens ?
does it feel like the tranny goes into neutral , or does it start stuttering and shaking a little ??

its kind of like the truck pauses for about half a seond and then starts going again. I can definitly say that it is mushier than the WOT shifts. It only happens on light and meduim throttle. On WOT, it shifts hard and quick.

Kyle, just got your PM. It could be that your truck simply prefers some additional line pressures over what I normally keep the programs configured at; or there may be an underlying hardware issue.

I will catch up with you early in the week to update the files and hopefully eliminate the issue.

thanks Matt. I just thought if someone else has the same problem, they might chime in.
