Chevy Tahoe Transmission Problems



  • jonayjonay Posts: 5
    I have a 96 tahoe 2 door 5.7 4x4. Driving down the road today and stopped being in
    gear, reset the code, disconected the battery to rest also, checked the drive line, checked to see if the tourq converter was connected. I have no R, no D, 1, ,2, 3.

    Time for a new transmission or is there something I don't know?
  • 1999 Chevy Tahoe 5.7 4x4.Same thing happend to me today. transmission was not making noise, not slipping and has been shifting flawlessly. Was stopped at stop sign. Stepped on the gas to move forward, rpm went up but no D321 or R. After sitting for a few minutes it would engage again but only for a short time. Fluid is full, no visible leaks, no slippage or audible noise. Had it towed to a transmission shop for inspection. No answer yet.Don't want to get ripped off!! Anybody have any insight on this?

    I'm getting a new trans soon $1400.00. shipped. I'd like to hear what they say is wrong with it though. If you need to get a new trans, I know a good place.
    I wish these guys would reply!

    can you post a URL to the place you get a transmission for 1400?

    Is it pulled out of another vehicle, a rebuild, or new? What kind of warranty?
  • jonayjonay Posts: 5
    its rebuilt. 1 year or 12,000 miles.

    call justin 800.409.1540

    where do you live?

    do you have a friend that has a shop?

    Don't currently have a transmission problem, had a 97 burb in the past with one, and had the local transmission shop fix mine.

    Just keeping track of what the different fix alternatives are, and what they cost.

    So in your case, you are going to have someone swap out the whole transmission, and it appears you have a friend who has a lift and labor who can help you do that. And then justin will take your old transmission back, rebuild it, and make it available for the next guy.
  • Transmission shop said trans needs to be rebuilt. Still dont know why it just quit without any malfunction or noise. $1895. for rebuild, new torque converter and the tow.
  • thanks for the reply to my questions.

    So after contacting several shops and getting prices it became clear to me that this has to be a pretty common problem with my trans since all off the trans shops knew exactly what failed when i described it to them. It has a broken sun sprocket which tends to wear and break after excessive abuse or a lot of miles which I have.

    The differences in prices were varied from over 2000.00 to around 1200.00 with just about every shop adding (give or take a couple hundred bucks). I kept my searches to local shops that took the time to talk to me about it on the phone and avoided the chain store type of operations altogether.

    So with a bit of knowledge about what it costs for parts for this repair and the care that is needed to do the job correctly I was able to get a reasonable price and a 2 year warranty. I don't have the final price yet since it is currently in the shop but I was told it will definitely not exceed 1400.00 dollars. and that is with a heavier gauge sun sprocket (after market part) and replacement of the planetary gears included in the rebuild. also the transfer case seal will be replaced since these tend to dry up and become brittle which allows trans fluid to leak into the transfer case. This I am told is a VERY common problem and can result in the loss of 2 quarts of trans fluid into the transfer case. And within only a couple years of age of the vehicle.

    And as for the clunking sound from the drivetrain , apparently GM considers this normal!!!??? This is what I was told by several trans shops and the fix that they use to try and alleviate some of the binding and noise is to improve the finish of the surface on the input shaft going into the transfer case and lubricate it well so as to improve its ability to adjust within the moment of its engagement. sounds a little sloppy from the get go, but hopefully that will help. It is a major annoyance and takes away my confidence in the soundness of the drivetrain. Unacceptable standard of quality if you ask me. I will be listening carefully if I venture into a showroom for a new vehicle.

    keeping my fingers crossed and my expectations high.

    I will post again with my impressions of the repair when I get the vehicle back.

    Thank you for your reply. I found a comany that rebuilds transmissions in Oregon that will sell me a trans for $1135.00 including shipping with 12,000 1 year warentee.
    If you know anyone that needs one call Justen 800. 409.1540.
    e-mail if i can help anyone.

  • When excelerating it won't go into the next gear, idoling real high wont go faster than 30 mph WHAT IS THIS?
  • My 2004 Tahoe with 71,000 miles has developed a new trick where it shifts really hard from first to second. It's really asserted itself now that it has cooled off here (the 50's). It shifts fine into 3d and 4th.

    Anyone have any insight as to what part might be wearing out. I'd like to be armed with some information prior to contacting dealers (who are looking to maximize revenue in a tough market).

    I have a '04 Tahoe too with 98 000 miles but have no problems like you describe but there is one thing I would do before taking it to anywhere to have it looked at any deeper - Change the transmission fluid. I had it done at 75 000 miles and I did feel some jerking a couple of times before fluid change.

    You might not be at the mileage what service manual calls for fluid change interval but harsh change between gears can be caused by break down of the transmission fluid.

    I know it is about $100 but well spend compared to changing transmission or having some other big job done to it when it really just needs new fluid. Make sure they fill it with correct fluid if someone else than the dealer shop does it.

    And you are correct, almost any shop, including dealer shops, try to maximize their profit telling people, who do not know better, that they need to service items that they really do not. This is why I would not tell the dealer or other shop about the problem you have when taking it for fluid change. I would just take it in and say you want fluid change because you feel your truck is used under heavier than normal load conditions.

  • I just saw this topic and had to post...
    I bought a used 2000 Tahoe in August and have not had trouble until the past month or so.

    I had to even have it towed last night!

    I seem to have the tranny slip like other have mentioned.
    I also have the problem when I'm in a gear, it may not be what gear it reads. For example I was in Drive but it went in Reverse. I put it back in park and went to Drive again. This time it did move forward but very badly and then I too heard a loud bang, similar to a truck that would have a fully locked locker in the rear, only this truck does not have that, just the GM Gov lock or what ever.
    Then it would move fine forward.

    Other times I put it in Reverse but it acts like I'm in neutral.

    Last night I put it in Drive and it would hardly move. The RPMs were way high. So again I put it in Park and tried again. Still the same. It seemed like it was trying to pull out in maybe 3 gear.

    I have issues too when I'm just driving it feels as though the tranny might be slipping but it will go on to the next gear.

    I have not taken it to a dealer...they seem to stuck on their "tech tool". They couldn't figure out the steering box whine on my husbands truck. I could tell them the steering box was bad and that a tech tool was not going to read that.

    Any ideas? So far some one mentioned to me a shift module or some thing there?

    I have a 99 tahoe, the button to select either 2H 4L 4H or auto 4WD is suppose to have one of the selections lit up when selcted and stay lit until changed. When I selct 2H it lights for a while then the light go's out and stays out. Is this normal or is there something wrong.
  • Mine does the same thing, I had my trans rebuilt recently and had the transfer case checked out and the mechanic said everything was good, but didn't mention anything about the lighted switch. so far no problems except for the lighted switch not being a good indicator of what drive mode I am in. So I just left it and I am careful to be aware of whether or not I am in 4wd. If you check it out let me know what you find out please. If it's a cheap switch I think I may change it.
  • I have a 2005 Tahoe. THe gear shift lever will move through the gears but it remains in park. There is something electronic that is preventing it from actually shifting and I cannot figure out what it is. I have checked the fuses and they all appear to be OK. Any ideas appreciated.

    Have checked to make sure the linkage isn't loose or disconnected at the transmission ?
  • jmaesjmaes Posts: 3
    According to what I've read in another Tahoe forum is that the switch has a bad solder joint and is prone to this on and off stuff. So I am going to try to either replace the switch or resolder the bad joint on my switch and see what happens. I'll let you know if that works or not.
  • i just bought a 2000 chevy tahoe, it was running just fine and now the tranny will not go into park. if i crawl under it and push the linkage slightly then it will go into park. any ideas on what the problem may be? is it the cable? is it the tranny? HELP!
  • I have not crawled under mine and ever tried this, I get hurt enought, but so far mine has not ever NOT gone in to park.
    It just doesn't go in the right gear when I put the shifter to that spot. Drive just might really be neutral, 3rd or worse reverse.
    I for the heck of it tried to just drive with it in the 3rd gear or what ever it's in and I get a huge bang and then its in the right gear. Seems to me it's not fully shifting in to the gear I choose.
    Now the truck will shift on it's own fine when I do get it in just Drive.

    Nothing shows on a Tech Tool either.
    Seems to only do this when it's very cold out. I have not had it do it all summer and we have had a few days inthe 50s now and it won't do it.

    Any one think this is electrical and weather affecting it?
