It is possible your truck my not be affected this bad, but the quick learn still needs to be done. There is reason the engineers created the quick learn process and why every manual lists it as mandatory.
Regardless if the memory is volatile or not, he can still drive around and the transmission WILL learn the new shift curve. He just cannot go WOT until everything has been learned which yeah, can take a while. if nothing happens within 150miles as I stated, then he is fine to drive, but that doesn't mean he can go WOT at that point in time.
Since he has a 2002, i don't even think a Superchips r Diablo tuner would reset his TCM parameters like mine would. I actualy think that might be the only way around the starscan tool.
In the ideal world, simply changing your transmission fluid and filter would require a quick learn of the TCM. While this sounds ridiculous to most, it goes with the same principles that apply to installing a new transmission, while the change may not be as harsh, there will still be adaptations needed to be made! Now, we all know, nobody does this when they change thier fluid or filter and just drive.
If OP can shift through all the gears with no lock-ups or problems as I already stated before, he can get by without any special programming.
The learning curve is done with the engine running and gear in nuetral with the parking brake set to warm up the fluid and then is driven and programmed via starscan tool. Might be better to warm up the fluid prior to the intial drive, but I think you guys are making this way more complicated than it needs to be. Isolated incidents are not a common occurence although irregular shift patterns may be experienced for a little while. it all depends on how far apart the previous settings are from what needs to be??
