Chevy Tahoe Transmission Problems

1679111220

Comments

  • I have a 2001 Tahoe 4X4.The trans works fine in 1st and 2nd. In 3rd it acts like it is neutral. In Drive it acts the same. It shifts from 1st to 2nd OK. When it shifts out of 2nd the trans disconnects and the engine revs. Does anyone have any experience or knowledge about this problem? Cost to fix? Do I need a new Trans? Thanks for your help.

    Don't drive it anymore, or you run the risk of further damaging from metal pieces moving around and potentially wrecking good hears..

    Had a problem couple years ago with my '97, lost (I think) reverse and 2nd or reverse and third. Local Aamco shop had free towing, so had them come get it. Turns out had a metal piece break. It broke, and a small metal piece messed up one or two other gears. The guy showed me the damage, ordered the pieces that he needed for replacement and put it all back together.

    I don't remember the specifics, but was somewhere like 1600 - 1700 dollars. A specialized transmission shops work on these all day long. When I had first called and described my symptoms, he was able to say.....I bet it's the blankety-blank (and should cost x). When he opened it up, it was exactly what he had suspected, and cost x.

    Not necessaryily endorsing aamco, just happened to be who I picked out of the phone book, and the local guy was great. YMMV. I'm sure there are many shops who would be as good.

    I have a 96 tahoe and when first driving it everything is fine, after about 10 miles check engine light comes on and when i make my first stop and try to accelerate the tranny shifts hard from 1st to 2nd and same from 2nd to 3rd all shifting after this is ok. If i pull over and shut vehicle off and wait about 60 seconds and restart vehicle there is no slipping but check engine light is on. Eventually the check engine light goes out after driving in town for long periods of time. Second problem is after engine light is on if i try to accelerate the rpm go up but tahoe will not move if i let off gas to a certain point it will speed up, i can only give it gas to a certain point any further accelleration it seems to bog down. Anyone with some advice please let me know also tranny has been replaced and old tranny did the same thing. someone pleace help. email ( autoshop1975@yahoo.com)

    I have a 96 tahoe. Everything works great except that if you put it in reverse and give it gas it makes a loud grinding noise. I was told by a mechanic friend that it is the TCM. I have done extensive research on the TCM and have found nothing for a 96 tahoe. As in where it is and how much to replace. Any help is appreciated.

    it makes a loud grinding noise. I was told by a mechanic friend that it is the TCM.

    Well personally, I would go get another professional opinion before putting money into a TCM replacement. The TCM is the electronic computer control for the transmission. Loud grinding noise sounds more like a mechanical problem, to me. Try a shop that specializes in transmissions, like AAMCO or equivalent.

    ....and oh by the way, I wouldn't be driving around with this problem before getting it repaired. You could get stuck somewhere and then have to incur tow charges, or if there are metal shavings or bits in your transmission pan, they could cause other damage to currently good parts if they get in the gearing or bearings.

    I have a 1995 Chevy Tahoe (it's a 5.7L, 4x4) with about 156K on her. My issue is a loss of power when the truck is accelerating in drive; it feels, sounds, and drives like it's a transmission issue. The problem started when I was accelerating up a fairly steep hill, the truck shifted down into 3rd to maintain 60mph and when I crested the hill the truck no longer would shift into 4th gear. There was no; bang, knock, pitch, grind, ect., nor does the truck any abnormal sounds now with said problem. Gear one only works if you downshift into D2 or D1. Gear two feels like the starting gear in drive. Gear three works without a problem. Gear 4 is missing, henceforth I can't get the truck into 5th gear. Currently I have the truck at a mechanic, though I've had a variety of people tell an even larger variety of issues. If someone could please give a general idea of the problem that would be greatly appreciated! Thanks!

    Need Help. Transmission wont work but when I shut down the engine and restart it will run in "3" only. Is this possibly computer related?
  • I had the same exact thing happen as to mgoodfellow (post #152) just before we were about to go on a long road trip.

    Our 2007 Tahoe LTZ blew its transmission with only 36k miles. Unbelievable. I'm a Ford guy and will likely not buy another Chevy again after this. Even with normal wear and tear, a transmission should easily get to 100k miles without catastrophic failure.

    I will say that Martin Chevrolet (in Los Angeles) took care of the issue right away and made sure we had a rental Tahoe to cover us while the truck was getting fixed. Tellingly, the dealer said their transmission repair guy was booked solid for several days when we brought our Tahoe in...

    Transmission works in ok in park,neutral,Drive,3 and 4 wheel. Can feel transmission engage in all but Reverse. Vehicle will move Forward in Drive,3and 4 wheel. Can hear slight click when placed in Reverse,not as pronounced as in the other gears. Will not move in Reverse, will not move with gas or manually pushing backwards. As a novice mechanic, tried and inspected everything repair manual said. NEED HELP BADDDD. Thanks

    Gotta call AAMCO (or some local transmission shop)

    Had similar symptoms in my 97 couple years ago. There is a splined cage that is known to break. Pieces broke off, and floated around, causing two other gears to need replacing.

    Don't drive it anymore (risking further damage), have it towed to a transmission shop. Get out checkbook. I saw my broken parts when they took it apart. If your problem was anything like mine, it's not something you are going to fix yourself. Good news is, transmission shops give you a warranty.
  • I bought a new Tahoe LT in 2005 and about a year after, I started having problems. It started to make a clunking sound in between gears, and sometimes while driving. I would feel a vibration, but not very strong. It was periodic, and every time I took it into the dealership, I was told that they couldn't duplicate the sound. I have had friends in my car and was told by them that it sounded like transmission issues (which I told the dealership). Last week, the sound and vibration became considerably worse. Yesterday, it was so bad that I thought I was going to break down, so I drove it to the nearest dealership. They are telling me it is a transmission problem (torque converter and a few other issues that go with it). I was told I have to fork up $1800 since it is just passed my warranty....yet I have complaining for years....

    Did you get this problem solved and if so...what was the solution?
    My boyfriend is having the same problems and we are in Colorado and he has to ge to Utah. I decided to look in a Forum to see if there was anything other than shelling out 5G for aa new tranny to fix the problem. THANKS
  • got one for you guys,

    I have a 2003 Z71 Tahoe, 146,00 miles. all of a sudden now it wont engage into 4 gear nor come out of 3rd once its gets there so 50mph is my max speed.. I've replaced the solenoids, ignition switch and checked all the fuses and still got the problem!!! ANY IDEA'S??? the guys at the Transmission shop dont want to touch it b/c they said it was an electrical issue and there was nothing wrong with the transmission.... any ideas would be helpful.

    The vehicle has 155K miles on it, shouldn't be complaining about reliability.
  • The motor is outstandingin my tahoe, but I was about to track down the first owner to only find out he had put 2 tranny repairs on it. First was a rebuild. He had flushed it before he finally gave up and traded it in.
    Ugh
  • I had my tranny rebuilt about 2 years ago, and recently it was hard shifting into second gear, and there was no power at all, I took it to Eagle Auto when it was rebuilt, and it turns out they put in a spring backwards, so when we had the check up done they found that in about 7 pieces just clanking around my truck, thank god me and my kids are safe. Then when I started it, it almost died, but it didn't so turns out we needed a new fuel pump, and filters. Now that thats done my truck is back and better than ever. it has power again. Now I just need to get the passenger window to go a little faster when it rolls up and down, and some of the lights on my radio are out. Maybe I need to change something to fix those???? ;)

    My tahoe Z71 was bought new and well maintained. After fighting the speedo cluster issues w/ my dealer, I'm just fed up with them. The tahoe has 98k miles on it. It seems to be missing 2nd and 4th. I can very tenderly rev to about 1800-2200rpm's let off accelerator and then allow it to shift w/ slow acceleration to what is probably 3rd gear and then same routing to get into 5th.

    My local tranny expert who comes highly recommended seems to think emphatically that it is the band which will require a costly rebuild. I'm just wondering if anyone has experienced this and found it to be electronic or possibly just needed a flush and new filter as it is due at 100k.

    Ironically, but not at all funny, about 2 months prior to this issue, the truck started burning excessive oil - as in up to 4qrts or more in 1000miles and 3 in 500. I don't typically drive this vehicle so hoped that perhaps it was tied into higher rpms w/ the xmssn. Reminder - the oil problem started 1st though. I drove and babied the truck for the last 500 miles and it is down to just the hash mark on the dip stick which I'm thinking is close to 3 qrts.

    Has anyone experienced either of thes and come to any successful resolutions?

    After reading all of the problems on the transmission I cannot believe GM has not recalled them.

    Thanks in advance

    +1 ;local tranny expert

    A transmission guy who works on trannies all day long, can pretty well nail the problem just by the symptoms.

    You don't want to be driving the vehicle in the condition it's in, you can cause more damage to other gears with the gear pieces loose and broken off in the pan.
