95 Blazer trans stays in overdrive and skips second gear
 

Hello all, I am attempting to repair a 95 Blazer I just purchased for my Mother-in-law. I am a Master tech but I am looking for a second opinion. THe vehicle drives perfect except it skips second gear, then after it shifts into overdrive and you slow to a stop, it stays locked up in overdrive until you shift the selector into first gear. Then you can put it back into drive or shift manual. It will still skip second. My diagnosis at this point is a solinoid possibly the 2-3 shift or lock up solinoid malfunction. THere is a code but I have not pulled it yet. Just got it today.

Has anyone experienced this with a solid fix? I have run into this before on passenger cars with a lock up solinoid but I do not remember them skipping second.

I was unable to find symptoms exactly as you stated in the symptoms diagnosis of my 4L60E ATSG manuals.

Here is one for 2nd & 3rd ONLY or 1st & 4th ONLY:

I did find a symptom chart for a "No TCC Release" condition which sounds like what you are experiencing with the "stays locked up" comment.

What happens when you manually put the shift lever in 2nd? What positions do you have for the shift lever for forward gears (OD, 3, 2, 1)?

Thanks, I have 1,2,3,OD. If I start in 2 maual it stays in forst and never shifts to second. Same if I downshift from 3 to 2, goes to 1st. I pulled valve body today and started testing solenoids.

Hey schreckman, Have you had any luck yet. I'm having almost Identical symptoms on my 97.... Manual 1st is good, no 2nd and seems to want to take off from a start in 3rd if I just put it in drive. Once I'm moving all seems fine.
