Can a dirty or failing MAP sensor cause a hard shift ?

After 2000 Buick used the 4T65E which are controlled electronically unlike the previous generation (4T60E) which are controlled by engine vacuum. So the answer is NO.
If you're having lazy shifts followed up by harsh shifts as the tranny warms up you could benefit from a TransGo shift kit. It made my tranny feel like new.

I keep getting adds for a dog hair chemical for clothes but Amazon decided I really need more things like that so they just show me pet crap all the time. I have a dog but my god she has toys and a collar and bowls she’s fine
