It's been so long ago I don't remember what exactly the problem is but it was not worth the repair - it was major. I had exact same issue and it gets progressively worse. We tried several things via dealer and no go. Finally learned its a part that they used at this time of inferior quality - and cost of fix was more than value of the "truck". And that was 4 or 5 years ago.
#499 of 505 No 3rd Gear in 2006 Chevy TB LS
May 30, 2013 (6:17 am)
I am having an issue similar to many on this forum where my TB doesn't shift from 2nd to 3rd. I even tried the 1-2-3 drives on my stick and the 3 will not engage. Checked the fluid level, that is fine. I fear the cost of getting the trans rebuilt, lol. Are there any bulletins or advice you might have on this issue? The last 8 of my VIN are: 62286302. I have around 136K miles on it.
#500 of 505 Replaced transmission but won't fully engage
Jul 13, 2013 (9:23 am)
I just replaced the automatic transmission on my 2003 Chevy Trailblazer (4.2 I6) with a rebuilt one I bought from a reputable transmission shop in Denver. I do realize that even a rebuilt tranny has the potential for problems but before I yank out the rebuilt transmission out I need some help troubleshooting - PLEASE.
Problem: The transmission won't fully engage in drive and does not engage at all in any other gear (R, 3, 2, 1).
I will preface this by saying I have checked, double checked and checked again, at least 6 more times, all of my connection including oil cooling lines, electrical/wiring, transmission fluid while in park/idling and everything else I can think of.
Here is the situation...
The transmission and transfer case was removed from the engine block as a single unit. NOTE: It was a cumbersome and heavy SOB so if you are a DIY'er, like myself, I would highly recommend you remove the transfer case first then the transmission. The torque converter was NOT removed.
The removal and replacement of the transmission and transfer case was uneventful. Once everything was put back together, I filled it with 11 quarts of Dex VI (recommended by many on this forum) that I bought ($$$ - practically had to finance) from Chevy dealership. The capacity for the torque converter is 6 quarts and the pan is 5 quarts. I then started the car and let it idle while I checked the transmission fluid level. It was 6" up the dipstick so I assumed two things: #1: Either the torque converter was already full (since I never removed and drained it) and I overfilled the system, OR #2: The fluid didn't have a chance to circulate through the system. To test assumption #2 I shifted through the different "gears" (R, N, D, 3, 2, 1) while idling and in doing so I realized the car would not move in any gear. I left it in each gear for 10 seconds and shifted through all gears at least 5 times - to no avail.
The next morning, I jacked the car back up to check, yet again, my connections. I also tried starting the car, checking the (overfilled) fluid, and then tried putting the car in the different gears - while it was up on the jack stands. I noticed when the car was in "Drive" and I pressed on the gas pedal the rear tires would turn but only if I really accelerated. There was clearly no power to the rear end but it did have some (very little) power. None of the other gears would cause the rear tires to turn.
I went and removed approximately 5 - 6 quarts of transmission fluid from the pan. I then re-started the car, checked the dipstick and noticed the level was still high (3" up the stick) and then shifted the transmission through the different gears to see if the tires would turn. No change - When in Drive, the rear tires would turn slowly when accelerating. Otherwise - nada, nothing.
I am at a complete loss and cannot figure out what I am overlooking. It seems that fluid is not circulating but I don't know why. What steps do you recommend I take in troubleshooting this mystery?
Some of my thoughts are:
- Reset transmission?
- Vacuum leak?
- Bad electrical connection?
- Too much fluid?
- Wrong fluid type?
- Bad transmission?
- Take it to the shop to check codes?
- Donate the car to charity?
Thank you, in advance, for your help.

I am having similar problems I have over 200,000 miles and it has been a good car other than oxygen sensor up til this point but my car will drive fine for a min or so then as you try to give it gas it will not engage After this happens you turn car off for about 30 sec then turn on and it will go for another min fine and then do same thing I am thinking it the trans sensors but not sure can anyone make suggestions to what they think this might be?
Thanks so much for input

It's been a while now, but I know we never fixed it and it got progressively worse. They told me that in those models Chevy used a cheap or bad transmission and the whole tranny would need replacing. It was a company car and they got me a new one rather than repair.
