Hello guys Im working on a 1994 buick regal with the 3800, Transmission operates fine if you ease into it but if you punch 50 percent or more throttal it it seams to jump into third or forth and stay there unless you manually shift it. transmission is newer 50k on it and has had a recent fluid change car has 230k miles on it any ideas what would be causing it not to downshift?
Iv been doing research all day and haven't found anything no check engine nothing just wont shift in auto any ideas would be appreciated.
