i am looking for a repair manual for an 83 Camaro 5.0 HO manual tranny. ive been looking everywhere for a repair manual for this transmission but come up empty handed with the exception of one i found on ebay thats a download for the computer.....not so sure its real. does anyone have one i could buy or borrow to finish this rebuild? i just can't finish 2nd and 3rd gears. ive been told there are two gears that are almost identical unless you know what youre looking at but i don't know which ones they are. let me know please.
