Has anyone out there had transmission reprogramed for different shift points and firmer shifts? thx in advance for anyones help.
I think the shift points are dependent upon your driving style - it will "learn" your habits. You can disconnect the battery to make it forget your style and it will learn quicker, or you can keep your style, and eventually it will learn it.Oletrucker said:Has anyone out there had transmission reprogramed for different shift points and firmer shifts? thx in advance for anyones help.
reprogramming has nothing to do with how hard a tranny shifts...even on todays modern transmissions there are still pneumatic elements to it that can only be altered physically...Oletrucker said:Has anyone out there had transmission reprogramed for different shift points and firmer shifts? thx in advance for anyones help.
Not quite. You can reprogram the TCM to use a harder shift pressure and you will get a firmer and faster shift. Many hand held programmers do this these days.gar187er said:reprogramming has nothing to do with how hard a tranny shifts...even on todays modern transmissions there are still pneumatic elements to it that can only be altered physically...
never came across this in the few different makes ive had over the years...this mainly a domestic feature? seems more prone for failure if the computer controls the pressure....bballr4567 said:Not quite.

even newer cars do.....but it most be a import/domestic thing.....seeing as i'm coming from imports....bballr4567 said:They seem to last fine in plenty of powerful cars. I have a friend who has had a hand held tune on his 2001 Trans Am for about 6 years. Trans went out at 130k miles when he let it shift at WOT from 3rd to 4th. Very, very common issue even without a tune though.
Lots of G8 GTs have a handheld tune as well and they handle it good as well.
Yes, older trans used to have to have the valvebodies switched out because they were incapable of variable pressure.
