4L60E Problems

What can I do? 3rd. and O.D. is gone.

I think it may-be the computer. The guy at the tranny shop said it could be the computer, had to hook it up to the dianostic computer and do some physical checks, to the tranny. Could it be the computer, I think it may-be. There's NO other problems, as far as the tranny goes. It drives just fine, all I have is 1 & 2 gear.

Again seems to me that the computer threw a code, so 3rd.and O.D. is out.

Did it throw a SES light? Got the code?

No 3rd and fourth but 1st and 2nd normal , is likley not and electronic issues , heres why ? 1 gear is both solinods on , secondi one off and one on , third is both solinoids off. fourth is also one on and one off but reversed from second gear , Have you had the car scanned for codes ?Is the 2-3 shift just not happening or is it actually and 2-3 neutral If its a 2-3 neutral you are definatly dealing with a mechanical issue ,
scanning it with a good scanner showing data feed will tell all , Look for the 2-3 shift comand , Anyway if you will get what eve codes are there and send them to us we will help you in anyway we can with figuring out your issue
thank you
