has anyone tried pulling fuse 47 on the AT cars?
 

i was reading and it seems to make the automatics shift crisper.

So does a tune. I wouldnt pull fuses to disable something that you know nothing about, easy way to cause damage to a great tranny

you pull it for about 10 min and reinstall it. it is supposed to reset the adaptive learn for the transmission

As stated crisper shifts would come from a tune. Pulling and resetting a specific fuse isn't going to do anything.

I will let you know. I have read in four different forums that it does, so we will see

I've heard you have to do it quite often too, best to get a tune.

Its the wives daily driver, so it would ve a track only thing. I am happy with power it makes. I just think there is some to be gained from a better shifting transmission.

Taking the negative battery terminal off for a minute does the same thing to reset adaptive learning in the tranny and ECM
