Well some of o might remember me posting fuel pump problems, well finally i got my 94 z28 running i bought the car a month ago but haven't been able to drive it more than ten minutes, i took it out today to test the fuel pump and wut happened is the transmission wouldn't shift properly, its an auto, i would step on the ga, not flooring it, and the gears wouldn't kick in, the rpms would maxout till i let the throttle loose a little then the gear would go in slowly, then in reverse the car shakes quite a bit kinda jerky when i'm backing it in to my drive way , wut do u guy's think is wrong? give me all possible problems u guys think of, also keep in mind the car wuz not driven for over a year,

 

i really cant answer your question, but before a Mod gets on you, this belongs in drivetrain tech.

 

you need an overhaul,
