Sometimes it won't shift in 3rd at WOT
Hello guys and gals,
I'm having a problem with my 89 Firebird, 2.8L, automatic... When it is supposed to shift from 2 to 3rd, it doesn't wanna shift at WOT. Sometimes it shift but it is like 1 on 4 try. Anything I can do about this? thanks

I know abosolutely nothing about transmissions.
But as for a suggestion, if you don't hear much back from here, I would suggest posting your question in the Transmission section, they might be able to better help you.
