no, dont see or hear any leak.
just seems strange how a vacuum leak would arrise just after i get gas.
I did more searching and found some stuff about the tranny.
If the TCM is crap or anything else such as a dirty fluid, it could throw the CEL for the tranny and put it into limp mode.
restricting my Rpms and what gears i can use.
long shot but its all i can think of now.
