Chevy Tahoe Transmission Problems



  • dmntddmntd Posts: 20
    I cant say for sure its a common issue but I do know I have seen many reports on here saying folks have replaced the tranny several times before they even hit 100k miles. I have not heard anyone having issues with their differential and I am knocking on wood right now that it will not be my next issue with this damn SUV.
  • They could sure use a lesson from Ranger Boats. I hit a pothole in my subdivision last year while pulling my Ranger out. The pothole broke both welds on axle and it rotated up to where tires were rubbing on fiberglass fender. Long story short, 3 yr warranty had expired the YEAR before. I sent them pictures of the hole, my tire, fender and axle. Out of good will and standing behind their product they send me a brand new axle and two new tires. So, if you are looking for a bass boat, Ranger will definitely stand behind their products.

    MY 07 Tahoe's transmission just went out with a little over 59k miles, still under the powertrain 100k warranty but time ran out last sept. Guess what, after a lot of wrangling they split the bill with me 60-40 which was appreciated, but for one of their top of the line vehicles to have tranny probs with less than 60k miles doesn't bode well for this vehicle and from what I am seeing a lot of other Tahoe owners are or have had the same problem.

    I just bought a 2000 tahoe with 235000km on it and now the tranny won't shift by itself. If i shift it myself it works but no overdrive. Does anybody have any suggestions what it could be Any help would be great thanks

    I was coasting down a mountain about 55 MPH when my transmission went out. Then I tried to speed up on a level road and all I saw was the RPMS go up. Now the transmission won’t select any gear even in Park it will roll forward. I checked the shift linkage outside and inside the transmission and everything seem to be working normally. I looked at the level of the fluid before and after engine start and it does not change. (Possible bad pump). Is there anything else I should be checking for before a transmission rebuild? Also I think I can get a 2002 transmission cheap but I don’t know if they are interchangeable
  • Look into the Transfer case sensor. Use youtube and search transfer case sensor. Google that as well. Cost to replace on 2006 4WD Tahoe was $700.

    With all the same issues on the Tahoe and Yukon transmissions I suspect that GM is looking at a Class Action Law Suit once the general public starts adding it all up. My new transmission (about a year old) is starting to do the same thing that the original one did. I've been to the dealer twice and its a "not trouble found" answer each time. I would think that GM would start putting it all together and find a real fix for the problems with these transmissions. Should a transmission only last about 80K miles? It shouldn't matter how old the vehicle is, the mileage is the key .
  • Transfer case sensor? The transfer case was getting lock on 4 LOW sporadically after some heavy rain I assumed it was the electrical connector taking in water. Thanks I’ll check it and get back with the results.
    I can get a 2002 used trani for about 300.00 but I don’t know if it is interchangeable
  • My husband and I purchased a 2007 Suburban in December of last year. We have four children and have a very tight budget so we decided to buy a used vehicle believing in the Chevrolet reputation. The vehicle had 72000 miles on it when we brought it home and immediately noticed the oil consumption was about a quart every 3000 miles. Not thinking it was a bid deal from what the dealerships were telling us we went with it because we loved the vehicle. Now we have 83000 miles on the vehicle and burn a quart and a half every 3000 miles. That's when I started researching the vehicle only to find I am one of many. Our local chevy dealership won't start an oil consumption test unless we have our oil changed there, the problem with that is we get free oil changes from the dealership we bought the car from. We can't afford to trade this in without being upside down, can somebody please help me with what I should do next.
  • Need a little more info. Did this 2007 Chevy Suburban come with a warranty from the dealership? If so how many miles does it cover you for? Did you report any oil concerns over the past 11,000 miles to the dealer you purchased from? Most IMPORTANT did you report any concerns to the dealer within 3,000 miles of owning it??? :confuse:

  • I lost drive and 3rd. First, second and reverse continue to work. I removed the pan and changed the filter and fluid, saw nothing in the pan. Still have the same issue. Any ideas of what to do now? Have approx. 145,000 miles on Tahoe, second owner and well maintained vehicle.
  • hwarner, unfortunately I have a 2007 Suburban with 148000 miles on it and the same thing happen to me. When it happen to me I could put it in first gear and take off manually shifting up to drive. Turns out a bearing fell apart and I had to have the transmission rebuilt. $1600.00 ugh!!

    My 2005 did the same thing this time last year, after having the CPU scanned I was told the throttle body was bad by the Chevy dealer, and then was told by another shop the transmission was shot. To be totally clear it was something like a belt or something for 2nd and 4th gear that was bad but it was the same price in labor to drop the tranny so I had to get a new one installed with a few upgrades. It sucks that my car only had 70k miles on it when it went out and was told the tranny's Chevy used are crap! My cost for upgrades and all was $2900 parts and labor.

    Thanks!!! It's time to just start calling around and see about a new one.

  • Toyota Tacoma is the best truck i hav ever owned besides my 95 chevy..
  • Thats is number one problem. u never wanna pull any trailer in over drive or u asking for trouble out of your trans. its not make to be hauling taier in over drve
  • The speed sensor will make a tranny act plum stupid if your speed ometor not working or acts funny i would try that first it fist one of mine.
  • My xmsn went bad a year and a half ago at 74K miles and I had to pay for a new one to be put in at the Chevy dealer. Now at 81K miles it's starting to do what the old one did when we first got the truck (and I believe that it contributed to the xmsn failure). The torque converter lockup is not unlocking properly. Going up a hill the engine labors until you really get on the gas pedal. My MPG has gone down to 12 mpg around town. The dealer replaced the valve body under warranty (3 year warranty) but that didn't fix it. Does anyone know if the TCM can be reprogrammed to change the unlock point? It just doesn't unlock soon enough and that will kill a transmission early. If I lightly touch the break to unlock the torque converter it runs exactly like new. Any ideas?

    Needless to say, I have a very unhappy family right now. We turned onto one of the busiest roads in town and it felt like the tranny was in Neutral, yet the shifter clearly was in D. Tried 3rd and no dice. Flashers on in the middle turn lane going 25 in second with cars flying by in both directions was frightening.

    We went directly to the dealer to find out even though we are under 100,000 miles at 94,000; our 5 years had expired on our 2007 Tahoe LT. $61,000 for a loaded SUV and the tranny goes out under a hundred? Really?

    This is my second Tahoe. My 2001 ran like a top for 170,000 miles. So I bought this one. I've had 4 Explorers and one Expedition - none of them had major problems. Now I am sitting here 200 miles from home in a hotel late at night while the family is sleeping, trying to find a solution
    on the net. I hope GM Customer Assistance comes through and restores my faith in GM.

  • Good luck with Sarah from Gm. My 2001 tahoe transmission went out at 16000 miles and again at 32000 miles. GM told me it would be covered if it went out again due to it being faulty from the get go...well transmission out again at 88000 miles...and they will not stand behind it...but they would give me 2500 discount if I bought a new GM....GM lost me as a customer...but Nisssan got a new one....Love my new Nissan!
  • OMG! The same thing just happened to me. I have always owned Chevy's. My dream was to own a Chevy Tahoe. Well my dream came true when I bought a used 2006 Tahoe Z71. I always thought I would have my Tahoe forever, but just recently I was backing up and heard a big clunk! Now I barely have reverse, I can only go about 10' till it completely won't go ( like I have the brakes on) and it will also go forward in neutral! I thought to myself, no big deal Chevy has a 100,000 warranty. They don't! My tranny was only good for 36k! Really!? My truck only has 84,000 on it. Now what? I have 2 kids I have to take to school and sports and I'm 6 months pregnant.... I don't need this! I have no extra $$! This is the only transportation I have. I called the dealership and the guy in service told me I missed it by 1 year to get the 100,000 power train warranty. I missed it! Sorry you got screwed! Is this legal? I don't understand when you pay so much for a vehicle, they will only cover you for 36k miles. Anybody know what I can do? My friend said the tranny has to be replaced.....$3600! ;( Chevy?! Why!?

    Hello soccormom1,
    Unfortunately, it is true that the 5 year/100,000 mile powertrain was not introduced on all models until 2007. However, the warranty expires on whichever occurs first, mileage or time; even if the warranty was included on your 2006 it would be expired by a hear and half to two years.

    We can look into this further, but I cannot promise anything up front. Please email us at (include your name and contact information, the last 8 digits of your VIN, and a summary of the situation) if you're interested.

  • We bought our Tahoe used 3 years ago. Transmission went out around a year and a half ago. Warranty just expired. Chevy split the cost since it was close. Went out again 4 months ago. They fixed (now its under warranty again) Went out again two days ago. They are fixing again. What is going on. We are worried about when this warranty runs out. (in another year or so) They don't seem to think this is strange. Am I the crazy one here or is this not right. From the beginning our engine light and traction control and stabilitrack service lights have been on. They did tones of warranty work and never was able to get those lights to turn off. Now of coarse that warranty is over. Any thoughts??
