Auto trans not shifting above 2nd gear
My 4l60e isnt shifting above second gear, when it comes time to shift from 2nd to 3rd it just revs but when i slow down it goes back into second, i was wondering if it could be a trans speed sensor or trans control silenoid before i decide to replace it???? Anyone got some input??

If after the 2-3 shift it continues to accelerate, but slowly with a lot of slipping, it is a worn out 3-4 clutch. However, if it revs like in neutral with no acceleration at all, it might just be the 2-3 shift solenoid (called Solenoid B). Now, it could be a completely worn out 3-4 clutch, but lets be hopeful.
