2-3 or nuetral?
i have a 4l60e trans that came in a 97 trans am 5.7. i start out in 1 and shifts to 2,when it tries to shift to 3- nothing- like it goes in to nuetral. when i romp on the gas it downshifts to 2, but when it tries to upshift to 3 -nothing- i was told that it might be the shift solenoid. so i replaced 1-2,2-3 solenoid, did'nt help. i'm looking for a cheap fix ,if possible - not sure if i need a rebuild. changed oil and filter and checked all wires. does anybody have an idea what could be wrong and how to fix? any input will be great
