    GMPP 6L80 Bolt In?

    2400-2800 stall? Saw this in a description... "Do not use this transmission in place of a GM service transmission – the calibration in the transmission control module is not compatible with production systems" Wonder why it won't work. Maybe there is some difference that requires a custom...

    Retractable Cargo Cover

    Just seen this ebay seller that seems to carry both auto and manual cargo covers.. Looks aftermarket new, not factory. https://www.ebay.com/itm/306299278748 https://www.ebay.com/itm/306211257913

    Door hinge issue

    If it was like mine, I doubt it. Seems like the roller kit or new hinge are the way to go. I removed the spring so I don't have to hear the creak/crick sounds in the meantime.

    PULLING MY HAIR OVER A P0301 code!!

    Your PPV still comes with AFM unfortunately. To check them, you can remove your valve covers and make sure the rockers aren't loose. Might be worth doing a compression check since it's still missing after a new plug. Did you swap spark plug wires as well?

    2011 Yukon Denali HVAC Module

    Same here, Ebay. I did not have to program my replacement module, possibly I just got lucky with the same options.. (On my second used HVAC module) One option that might affect programming is 3rd row climate controls.. (My first used module had problems controlling the rear)

    Engine oil cooler line removal question

    Did mine without dropping diff or driveshaft. (engine cooler & transmission cooler lines) I bent the old trans cooler lines to radiator when removing them, but was able to snake the new lines in.. (I might have just been impatient whilst removing them..)

    2013 Tahoe stock for stock radio swap issues

    Need to get it unlocked. No USB connector on the new unit? Not sure about the extra connectors, they could be for rear entertainment or something you don't have/need..

    Code P2138, Reduced Engine Power and Water Intrusion

    Maybe check the pedal position to make sure it responds smoothly to your pedal inputs? Just to rule that out.. I would think ACDelco installed it properly, yet I wouldn't be totally shocked if it was off for some reason..

    Code P2138, Reduced Engine Power and Water Intrusion

    Might check the TPS for correct installation.. Needs to be installed with throttle blade open.

    AC troubleshooting Help/Solved

    You're right! Maybe the wire from ECM to relay interrupted somewhere.. https://charm.li/Chevrolet/2008/Suburban%204WD%20V8-6.0L/Repair%20and%20Diagnosis/Diagrams/Electrical%20Diagrams/Heating%20and%20Air%20Conditioning/HVAC%20-%20Automatic/

    Hard Starting at Temperature, P0175

    Check your ethanol %. Even though you only use regular gas, the ethanol is calculated off the O2 sensor readings.. Maybe try cleaning the MAF?

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I have a flat passenger mirror (glass only) you can have if you want it! I tried it, felt too narrow of a view. (didn't have a spot mirror) I like the mirror showing a little of the body side, for backing up when close to things..

    Heater quit working/blowing

    Front blower motor and resistor are under your glovebox. Need to remove underdash cover (3 screws, one near the middle) When you take that cover off, you will see everything.

    2008 Tahoe LT VCIM Swap

    Even with the two bolts out, the bracket just falls down a little which didn't seem to help.. Not much space to lift up before it hits the dash, some people cut the dash part above it. I cut my VCIM bracket because I eliminated the VCIM and no longer needed it.. (May have cut it just to remove...

    Help having electrical issues

    Flickering lights and things going on and off could be a gound/power issue. I would clean any grounds you can find and inspect the battery cables for corrosion/tightness. If misfires on 1&4 only, perhaps worn plugs or bad plug wires or bad coils? Swap them around and see if misfire follows.

    Lift gate assist buttons and the issues im having.

    The diagram shows the switches wired in parallel I believe... So you can make both switches work, but not when both are plugged in?
