I agree with remote starting to get the fluid moving to avoid the first 1-2 shift bang for the day. However, when remote starting my 8L90 after getting in and putting the key in the vehicle jerks forward, while in park? haha i think id rather force the 1-2 air purge shift than feel a bump in park?
I've heard lots of tuners can adjust the TCM to help with the harsh downshifts, anyone had much luck with this or even upshifting?
