    2011 Chevy Tahoe. Z-71 4X4.

    Welcome to the Forum. Someone else may comment on this concerning the 2007-2015 Tahoes. My Tahoe fits in the 2015-2020 date range so I am not sure about the 2007-2014 Tahoes. You probably have a 6L80E transmission: 6 forward gears, installed Longitudinally, 80 series, Electronic control. The...

    Transmission service, changing bypass thermal valve, part numbers?

    I got a GM reman 6l80 put in this week. I told the service advisor I wanted the service bulletin bypass valve. I was charged $88 for part # 86774933. I don't know if they happened to have some in the back or what. A December, 2021 copy of the service bulletin is attached below. There may be...

    Picked up mine from the local Chevrolet dealer this afternoon. Classic symptoms, slipping torque converter clutch, delayed clunky shifts, etc. Started at 121,000 miles. Drove it gently to get home from a trip. See...

    Sick 6L80 Transmission - P0700 & B2AAA, P0741 & B2AAA - Resolved $$$

    I dropped it off at Cavendar Chevrolet near my house yesterday morning. They said they could get the tranny overnighted in. They're going to do the rear main seal for one hour labor. When it's done, I'll make a report.

    214K 6L80 rebuild before TCC failure

    It's possible that the OP's transmission had had some fluid flushes without getting into the pan to replace the filter. Never the less, replacing the converter is a good idea. After mine went south after 123K miles, taking the tranny with it, I think that I would suggest replacing the...

    That's what you all have been suggesting from the start. I should have said OK and saved us all a bunch of time. For what it's worth, I know a lot more than a few days ago, but end up at the same place. Thank you all very much for your time and help. Rob

    Thank you Nick. It looks like Richard is back in business again outside of Amarillo, but the only phone number visible is the old one that is no longer in service. Unless he has more business than he can handle, he needs to make himself more accessible. I saw an old Jasper transmission sign...

    2016 Tahoe Factory Transmission Cooling Method?

    I have a 2016 Tahoe with the "NHT" Max Trailering Package with a sick transmission. I'm looking at replacement with a reman transmission. I've been told by a NAPA technician that the transmission fluid is cooled in the air conditioner condenser instead of in the radiator on the 2016 and later...

    I'm 78. I can do oil changes and fluid changes myself but not a transmission change. Nick, I understand your questions for the rebuilder, but am not sure if I will be able to get them answered. Assuming I get home, I'll make a list of them and see if I can talk with the AAMCO technician...

    Thank you very much for your info, Nick. If I am hearing you correctly, you are recommending a GM re-manufactured transmission. Apparently the transmission does not come with a torque converter. Thank you for the info on the lockup clutch lining thickness. Does the Jasper transmission come...

    Hi. I need advice. Situation: 2016 two wheel drive Tahoe with a 6L80E and the Max Trailering package. I bought the Tahoe three years ago with 80,000 miles and have put 40 thousand miles on it. It now has 123,000 miles. I had the pan dropped and the fluid and filter changed at 90,000 miles...

    Pros and Cons of going from 20" wheels to 18"

    As you've discovered, our spares are on 17" rims. No problem for the brakes. The Police Tahoes are on 17" wheels all around. Why the bigger wheels with shorter sidewall tires? IMO, the larger wheels and shorter sidewalls are probably a fad. Take a look at the wheels and tires on Nascar race...

    Switching 18” tires/rims to 20” on 2017 TahoeLT 4x4

    If you keep the same overall tire diameter, with a wheel with a two inch greater diameter, 20 inches instead of 18 inches, you will have one inch less tire sidewall rubber between the road and your wheel. That may not improve the ride. It may make it harsher. I am looking to replace my...

    Newb towing a travel trailer-Will lift gate open with a manual tongue jack?

    Only dumb question is the question not asked. :) My Tahoe tows my Casita trailer with a manual jack with no problem. I have a six inch drop drawbar. The liftgate has plenty of clearance with the Casita jack. The Casita has a hi-Lift suspension with 205/R15 tires. I replaced the 2 1/2 inch...

    Also, if the TPMS sensors are included, will the 2021 sensors play nice with my 2016 Tahoe?

    2016 stock 18x8,5 wheel offset?

    My new-to-me 2016 Tahoe LT with the Max Trailering Package has 20 inch wheels and 275/55R20 tires with maybe 10,000 miles left on them before the wear bars. According to the wheel and tire size sticker on the driver's door jamb, it is supposed to have 18X8.5 wheels and 265/65R18 tires. I'd...

    Bad day...thinking about a different grill, any suggestions?

    Typically contact with a bird or animal is considered the bird or animal's fault and is covered under Comprehensive instead of Collision coverage. As in "The deer hit my car" instead of "I hit a deer". Contact with a mailbox, other vehicle, etc. is covered under collision. Dodging a dog in...

    Help 2007 Yukon XL Denali 6.2 L Dies at idle

    Thank you for your research suggestions. I've told him to record conditions, elevation, outside temp, engine coolant temp, transmssion temp, when it happens. I suspect that heat may be a problem. I showed him where the injector fuel rails are. We'll see if it goes away in the wintertime in...

    Help 2007 Yukon XL Denali 6.2 L Dies at idle

    Per the subject line, my brother has a 2007 Yukon XL Denali with the L92 6.2 liter engine. I have looked through recent posts and did not find a situation like his problem. Randomly, it will die as he comes to a stop with a warmed up engine. There is not a problem with starting, so it doesn't...

    Towing Travel Trailer

    Sounds and looks like you're good, then. It used to be, before active air leveling systems, the protocol was to adjust the bars so that the front and rear of the vehicle both went down the same, with the goal being to split the tongue weight evenly between the front and rear. The biggest thing...

    Towing Travel Trailer

    Water weighs 8.3 pounds per gallon. Depending on the location of the water tank on the trailer, its weight might be primarily on the axles or in between the axle and the tongue, in which case it would add some to the tongue weight, which might be desirable. Or it might reduce the tongue weight...

    Finally made a decision, bought a 2014 Chevrolet Tahoe PPV w/ 41,000 miles

    I laughed out loud the first time it happened to me on my way home from picking up my 1995 Caprice 9C1. It was after dark. After a while, it became a bit of a bother having cars bunch up around me on the freeway, so I took it off. Back in 2000, I think the max speed in Texas at night was 65...
