    AGM battery in 2011 Denali?

    Have them in my seldom used Corvette and 96 Tahoe for at least 6 years with a maintainer charger. My 2001 Yukon AGM is about 5 years old. All trouble free. Put an H7 AGM from Costco (best price) in my 2015 Tahoe last year. I find them worth the extra money.

    Just had Torque Convertor Changed in My 6L80E to Avoid Future Problems (Hopefully).

    Another simple modification to make your transmission last longer is to purchase a DOD (displacement on demand) eliminator. It is a little $40 module that plugs into the diagnostic port under your steering column. It keeps your engine in 8 cylinder mode. Your torque converter is made to...

    Just had Torque Convertor Changed in My 6L80E to Avoid Future Problems (Hopefully).

    You might also have the engine’s rear main oil seal replaced while the transmission is out. Very cheap to do now but very expensive to pull the transmission again in the future. I suggest using the $40 upgraded thermostat ending part 86774933 with its lower 150 degree opening temperature instead...

    Overheating 6L80e

    Others are correct to plumb cooler lines into radiator cooler first, then into auxiliary cooler. Reason for this is that radiator temperature is never hotter than engine temperature and usually much cooler. After being cooled in radiator your auxiliary cooler will further reduce oil the...

    Overheating 6L80e

    Curious if slipping torque converter or clutch packs are creating excess heat. Did you run the adaptives to adjust clutch pack apply pressure after your rebuild? Have you disabled DOD? There is more converter slip when DOD is active. Also try driving in tow/haul mode to see if that helps.

    Rear Axle/Differential Rebuild AAR

    This is definitely the best and most comprehensive write up I have read regarding the c-clip type axle rebuild. I recently rebuilt my 9.5” 2015 Tahoe differential. It had been rebuilt under warranty at about 90k miles with new bearings and ring and pinion. Apparently they didn’t get all the...

    AC Leak - Pulling my hair out.

    Meant to say “a can of Freon would only last a COUPLE of days”. Stupid autocorrect changed it!

    AC Leak - Pulling my hair out.

    I have been searching for an elusive leak for a year. A can of Freon would only last a coffee days. I have done AC work for 50 years but this one has me baffled. GM decided to combine the AC condenser with the transmission cooler in the same unit. My Freon was leaking past the partition into...

    Copper Clad Aluminum wire on an auxiliary battery installation

    I use copper welding cable. Flexible, available by the foot, and easy to alder crimped connectors.

    Replaced my transmission thermostat with a lower temp thermostat

    Possibly shift quality. They definitely shift firmer when cold. People are much fussier than before about minor things like feeling the shift. Maybe a greater consideration is the length of warranty GM has to provide now.

    Replaced my transmission thermostat with a lower temp thermostat

    Has anyone tried replacing the plunger rod inside the valve with a slightly different length rod to reduce the regulating temperature? (Assuming you have a valve not too corroded to work with). It appears to me that would be an easy and free solution to reducing the opening temperature. I am...

    May have made a mistake.

    You have “Auto Level” suspension rather than “air suspension”. Magna ride is completely different and often confused with the auto level or the standard suspension. Of the 3 available suspensions, the auto level is typically part of the towing package on our trucks, the main reason for that...

    Update 5/2/21 - Bounce and Porpoising - Especially Towing

    I have found that porpoising is a problem related to the equalizer bars. I suspect you need stiffer rated bars. The trailer and vehicle should move up and down together as a unit over small dips in the road rather than pivot at the trailer ball. Your existing bars were probably adequate for...

    NBS rear spring options 2-3" drop

    Yes, I do still have them. Will PM you. I forgot to mention both sets of Belltechs are variable rate springs so a few coils are almost fully compressed, with more space between other coils. That premium design gives a stronger spring rate as the spring compresses, affording a better ride.
