#75 of 422 2003 Tahoe Transmission?
May 09, 2008 (3:16 pm)
I've reviewed the posts and have several questions. The truck has just over 80k miles.
My 03 Tahoe has started to make metallic clicking and clunking noises when putting it in to gear, reverse or drive after it has sat for a while and has cooled off. On occasion it seems like it clunks in to gear when getting started.
I've also noted last fall that the 4wd makes a loud clunking noise when putting it into gear.
I live in WI and like to use the 4wd but kept from doing that this winter as a result of the noise.
I am the 2nd owner of the truck. Would there still be any type of drive train warranty remaining on this truck?
Who would be best to service the truck? Chevy dealer or large private company?
From the description of the noises do you believe this would be a transmission problem or other drive train issue?
Any assistance that could be provided would be greatly appreciated.

this one is pretty wide open really u-joints differential pinion slop t-case all suspect I would suggest starting with checking the basics jack and support rear end (SAFETY FIRST) check rear drive shaft ujoints and pinion for slop. then repeat for front diff and drive line chances are you may find your clunking noise. if not located by this inspection suspect slop in t-case. please note that your vehicle is auto 4wd all 4 tires MUST be the same size or t-case failure/problems will become present

Thanks. I am hoping it is one of your first thoughts as opposed the the transfer case. Tires and wheels are the same size.
Am I assuming correctly that I should block the front tires when the rear is jacked and vice versa? Do I check for the noise in neutral with truck turned off and turning one wheel as opposed to the other? Or otherwise?

No more factory warranty on your '03. You would probably be better off taking your Tahoe to a GM dealer.

the whole trick is to be safe while you check your car/truck block the wheels, support the truck on jackstands.once you have the wheels off the ground you will be able to check the drive shafts and pinions for slop i have seen many vehicles that have 1/4 to 1/3 turn of slop on the differential which can account for some delayed engagements and also banging engagements its a matter of finding the noise. eliminate the most obvious and go from there. differentials, u-joints, t-case, body bushings, and so on
#80 of 422 Happened twice!!

I have a 07 Tahoe LT with 18,000 miles. About six months ago, I was sitting at a traffic light and started to accelerate. When the truck went to go in second, it missed and redlined. I pulled over in the middle of the road, shut the truck off and restarted. It seemed fine, so I go to where I was going and called the dealer. They had me bring it in. NOTHING was wrong!! I was very angry since I had an infant in the car and did not want to leave without having an answer. They had me bring the truck back in to replace some valve in the tranny. Ok, it has been fine, until tonight! I was on my way home at a redlight, accelerated and lost it shifting into second. This time I am stuck in the middle of the road, no gears except reverse, but cars were behind me!! I was less then a half mile from home. I shut it off and on, and played around with the gears. I got 1, 2, and R...no D or 3. I made it home and used Onstar to run diagnostics and they said nothing was showing up!! I went out an hour after I got home to see if it miraculously fixed itself like the last time, but no luck. It grinds like crazy in first, so I am going to have it towed in the AM.
I am sooooo disappointed. I grew up with Chevy's and love the new design of the Tahoe, but I am kicking myself for not getting the Sequoia or Armada...I hate to admit that, but we have an 06 4 runner and it has twice as many miles and never any problems.

accelerated and lost it shifting into second
I doubt this is the case but is it even remotely possible that you had not pushed the stick all the way into second? I once had a car in which you had to push extra hard to get it into first gear. Otherwise, it exhibited behavior as you described even though it felt like I had pushed the stick all the way..

Yes, I was at a stop, hit the gas to go and as it went to shift to second, it missed and redlined! I am not an idiot, this has happened twice. I just got my Tahoe back today. They replaced the sprag clutch. The truck is amazing and I love it, but just worry about it happening again. I would not even trust a new tranny since it is common in these trucks.
What makes it so impossible (or doubtful) that that was the case? A transmission cannot break while shifting?? Educate me...

Last year they replaced the sprag on my 07 Tahoe and I have not had a tranny problem since. You should feel confident that the issue is resolved.

I was suggesting no such thing. I merely conveyed that I had a somewhat similar experience.
