    Tru-Cool Max 40k Transmission Cooler

    Right on Honestly I'm not sweating about those temps. Sig needs to be updated. I'm just shy of 185k with the original trans. Just kind of a cheeky jab since I've seen them go out around this time. Actually iirc don't they like to conk around 160ish?

    Tru-Cool Max 40k Transmission Cooler

    Out of curiosity, what's your plumbing order for the cooler + radiator pass through, and what sort of temps are you seeing? Mine settles in around 100f on cold days, order is cooler, then radiator, then back to transmission

    What engine oil?

    So, that one *was* true. But context of the time. PAO base stocks cause seals to shrink a touch - so it causes leaks. We pretty quickly figured out that if we mix in some ester based oil, it 'evens out.' But that was in the 70s. It literally hasn't been an issue in the last 40 years. Much like...

    What engine oil?

    Echoing this Putting thick 20w50 oils in this is..... Ridiculous. There is literally no data to support running oil that thick in this application. What do you expect a high mileage additive to do? Where are you getting this information? Can you back this up in any way? I don't mean to sound...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    I missed the most important number on my odometer and I'm upset I looked down... And forgot to take a picture of 180085. I let the BOOBS slip through my fingers, man :( Also figured out I'm terrible at eyeballing weight. Was hauling a bunch of firewood. Uhh..... The 'hoe really doesn't much...

    What do I do with my 2003 Z71 Suburban?

    Knock insurance down to a reasonable minimum for the value of vehicles in your area Or, entertain the idea of per-day as-needed insurance. I know those exist, though I have neither experience nor input on providers For 3k.... The thing's worth more in utility than anything else. Burban has a...

    Re-circulation Blend Door - where/how/ehh?

    I just walked over to the back shop and pulled one of the techs aside. Did it on his lunch break. Slipped him 60 bucks for his time because the service writer / booking area wanted like $350 for it.

    Truck wiggles

    Vet nailed the checks If all of those come back good, couple more bits to check: - Rear bushings. Those are pretty straight forward to look at. For the 4 control arms: Shove a pry bar between the mount and the control arm and give it some grunt. See if it moves. It shouldn't. - For the track...

    Pan drop - defeated tonight

    Confirming it's hanging up on the shifter bracket? I've always just reached up there with a ratchet and disconnected the thing altogether. It's 3 torx bolts iirc. Don't remember the size. It's blind, but easy to do by feel. Shouldn't need to do much else. I've never had to fuss w/ the exhaust...

    2003 tahoe no crank no start

    Lets isolate and chop the system in half. Grab a multi meter, and lets look at the starter relay. 1. See if the signal gets power when you turn the key. I don't remember if it's switched power, or switched ground. Will be easy to check. Switched power = 0v on pin 86, energizes when start. Pin...

    Rear brakes still surging

    At risk of asking the obvious, have you rotated the tires? Sometimes, out of balance tires can only show up under braking

    Re-circulation Blend Door - where/how/ehh?

    Right on Expect to hear back from dealer tomorrow Depending on how much they want for it... I'm curious where that information is stored, and if grabbing a replacement unit is feasible. But that would only work if it comes w/ the updated range

    Re-circulation Blend Door - where/how/ehh?

    Oookay Update So, it seems to be over-ranging when set to outside-air. Which swings the door towards the interior against some plastic grating. If I stick my fingers in there and stop the door from ranging all the way, it works fine. If I remove my fingers and allow it to go to to...
