    No forward gears, but revers works after loud clunk at nearly WOT.

    Thank you for the info. I was getting a small amount of “clunk” when dropping all the way down into 1st, but still no movement. Now, I get absolutely nothing in any gear manually, or in D, other than reverse which thank God allowed me to back it into the shop. Got a lot of work ahead of me...

    No forward gears, but revers works after loud clunk at nearly WOT.

    Yeah, I chatted with them a bit and he believes the forward sprag is failed. I’ll be pulling this one out, and packing it up to ship to PA. Good that I have my original here for a spare, but definitely not looking forward to doing the work. Sounds like the forward sprag is not a common failure...

    No forward gears, but revers works after loud clunk at nearly WOT.

    Hey folks, been busy lately and not much time for my favorite forum. I’ve been maintaining my ‘03 and trying to keep her healthy. So I just had a mishap. Taking off from a stop, probably 70-80% throttle, and I’m not sure if it was on the shift from 1-2, but believe so. Loud clunk, and now I have...

    Engine swap

    Beyond what has already been stated, as far as I know, the 2019 engine is also an "LT" platform, using direct injection, as well as some other differences. Definitely not a simple swap. But if you were to swap all the PCM / TCM, wiring harness along with the mechanical portion, it's certainly...

    Brake Upgrade Help

    This, right here.. I upgraded mine to the GMT900 front calipers (2010), and also installed the Powerstop Z36 kit (carbon / ceramic + slotted / drilled rotors), along with all 5 stainless braided lines from Goodridge. The rears were already the better 2-piston GMT800 brakes, but also installed...

    My 2004 Yukon started itself when I connected the battery cables, no key in ignition.

    When I need to data log for tuning, I have 2 fuses I need to pull from my aftermarket remote start, or the tuner will not communicate with the ECU. I've done it a large number of times, but one time, while plugging the fuse back in, off she went. Thankfully, the fuses are under the dash, so I...

    2004 Denali gets hot when parked

    First thought would be air in the cooling system, or a worn mechanical fan clutch. If I read right, you haven't tested, or replaced the fan clutch? You should be able to burp any air out of the cooling system by parking the front end on an incline (hood pointing up), and running it while...

    Oil Pump Compatibility

    My Melling HV pump came with 2, maybe 3 different springs, to allow for tuning of the volume. Yours only came with one? (Understand you got the HP, not the HV)

    Best flex brake lines?

    I’ve been happy with my Goodridge stainless braided lines. Assuming the lines to calipers are what you’re referring to re: “flex lines”

    lower oil pressure 05 tahoe

    Based on what you discovered after the mechanic “rebuilt” it, I’m suspicious there isn’t an internal issue, such as cam bearings, or something else.

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

    Finally took some time to clean her up a bit. I hate having a dirty vehicle, but just don’t have much time these days..

    06 Tahoe Terrible Oil Leak

    Yes, I had an aftermarket oil pressure sensor give up after about 200 miles and it was a catastrophic leak, as in low oil pressure came up on DIC. I’d take it to a car wash, clean all the oil you can off, and see where it’s coming from. Oil pressure sensor sounds probable, and that would be a...

    Trans/Transfercase fluid change

    Definitely change the trans fluid if it’s brown.
