I have a Mustang GT 1991 automatic trans
when overdrive is on use the car turn very slow and you have to accelerate alot to get the tranny change to any shift.
exist anything to adjust the overdrive cable or to improve shiftting????

sorry for my english im not good at all speaking. my first language is spanish but i still practice

This is normal.You can get a chip or tuner to adjust the shift points but don't adjust them to shift too soon of it will drive you crazy.

what chip you recommend???

any tutorial or something to explain how to adjust that??? i like to learn by myself. i almost do all the repairs of my cars, friends teach me alot and i always want to lean how to do it, if is not too complicated.

anyways thanks
