    Trans Cooler question

    used the Mishimoto MMTC-K2-14 Transmission Cooler kit for a 2017 Chevy Tahoe 4x4 Premier. Amazing kit. Works excellent. High quality kit. Not too hard to install, but have to take off the front bumper. Kept the thermostat in place, so the cooler only gets used when the thermostat turns on...

    2017 Chevy Tahoe Premier 4x4 Trans service, rebuild, Dex VI fluid, MagRide

    Dang. So do y'all think is it likely to keep happening, and need another trans rebuild sooner that usual? It's at ~45k miles now. Warranty rebuild was at 39k miles.

    Hey Blackcar, thanks for chiming in. As I was trying to research the TSB you were talking about, I did find a forum thread that was talking about the Mobil 1 LV ATF HP blue label fluid...

    P0442 MIL

    I've got a long term P0442 code on a 2003 blazer... and its NOT the gas cap. 1 point for @PNW VietVet =) I think its the rubber tubing to the gas tank from the fill port though. Not sure. Need a smoker.

    2017 Chevy Tahoe Premier 4x4 35k miles oil change, dexros?

    I just ordered Castrol Edge Extended 0W-20 synthetic oil which said Dexros on the picture, but do not say it on the actual jugs that came, and have different approvals on the back. Will this be a problem. I know about warranty. But I doubt this oil is so different to actually cause any...

    So a company Spohn https://www.spohn.net/ has a trackbar/panhard-bar that fits the 2017 Tahoe Premier 4x4 with Mag-Hytec 12 bolt 9.5-9.75" diff cover. It has a bend in it that goes around the larger diff cover, and also is clear of the sway bar. In case anyone needs one of these, even though...

    2017 Chevy Tahoe 4x4 33" tires rubbing

    Hey I wanted to come back and thank you all for the help. The tire mechanic never ended up helping with the tire rub, today we just lightly sledge hammered it. The metal AC lines were right where you said they were and had we not known that, and starting sledging away without first removing...

    Mobil 1 212, 212A oil filter changes

    yeah Mobil 1 filters I think are still some of the best, but they have cheaped out in their newest update (the A versions), not just for Tahoe filters but other car makes. I guess stock holders run and ruin the day in today's age. And the business leaders to seek to please them with profits...

    2017 Chevy Tahoe 4x4 33" tires rubbing

    A tire mechanic is going to deal with this, I was just curious what know-how was out there. Not sure about wheel off-set. The mechanic did say the tire rub is fairly minimal and will be easy to deal with.

    2017 Tahoe Rear Differential Cover, Mag Hytec, hits rear crossmember

    I am ashamed.. but I bolted the track bar to the outside of the axle slot with a longer 1/2" 6" grade 8 bolt and nut. (also 1/2" washers inside the bracket for support) also, it was taken on a long trip recently and got 21 mpg, mostly highway not much traffic. MPG seems OK, no? Also a...

    Stabilitrak issue my journey so far.

    Did you calibrate your PCU when you got the 33" tires? stock tires are 31.6" in believe. I will be using this speedo calibrator soon myself. I think I read somewhere that 3% off in diameter will set speed sensor codes, and other things connected to wheel speed sensors, etc. I'm hoping the...

    2017 Tahoe Rear Differential Cover, Mag Hytec, hits rear crossmember

    Once were done dealing with the trackbar, and shave of some aluminum fin for better sway bar clearance, we are done with this diff cover install. I'm wondering about aeration now with the 5 quarts of fluid.

    2017 Tahoe Rear Differential Cover, Mag Hytec, hits rear crossmember

    No I have not done my research on this. Here is the inside of the Mag Hytec GM 12-9.5", and you are right it has a flat back, compared with stock. I remember reading something somewhere about extending a vent tube up higher to prevent spill out or something? is that the same thing going on...

    Hello all 2017 Tahoe Premier 4x4, replacing the rear differential cover with a solid aluminum Mag Hytec 12-9.5. However, it hits this crossmember, circled in the picture attached. What is the name of this crossmember, and do they make aftermarket replacements that go around thicker rear diff...

    2017 Tahoe Premier 4x4 where's the spare tire key on push button start?

    Hello all I am trying to get the spare tire down so I have more room to replace the rear diff cover with an upgrade. It has a push button start, but the spare tire hoist has a key lock. No key was given when the SUV was purchased. Should a key have been given when purchased? even though its...

    2007 Tahoe LT 4x4 5.3L gas 158k miles, how long do the engine's last?

    I think I am going to add some Mystery oil to the engine oil. Although I do have Sea Foam as well. Either one I could put in for longer term cleaning. The ticking is not horrible. It was purchased at 30k miles, and I assume it was taken care of well during that time. I would like to see if...

    2007 Tahoe LT 4x4 5.3L gas 158k miles, how long do the engine's last?

    From what I've learned about emissions readiness from the other vehicles I've worked on over the years.... if your I/M emissions readiness lights are not green "complete", you will not pass (at least here in CA). The only one that will not matter is the EVAP test. It can be "incomplete" red...
