    Transmission Chronicles

    So a lil while ago, my Trans lost all gears. I have a 2007 Yukon with the 4.8/4L60e So I’ve been searching for a replacement. I considered just replacing the pump. But don’t wanna just throw money at a trans and can get a rebuild. (Trying NOT to rebuild) So before I get to that point I searched...

    i got up under there the first chance I got and changed the O ring. But I’m now suspecting a bad pump. I on a nice write up that a loss of all gears was more than likely the pump. So I’m headed to the junk yard today to pull one.

    So I got it towed this morning. Right before a thunderstorm hit. I did manage to get under it while it was hoisted up. It appears to be leaking from dip stick. Would a loose dipstick cause me to lose enough oil to make the trans not shift at all? I did have a hard shift between 1-2 didn’t see...

    It was a steady stream. Almost like when you forget to cut the faucet off all the way. It seemed to be leaking from the pan last night. But it could be that. I didn’t notice any issues. It does have 210,000 on the dash mostly highway miles. I poured a gallon of fluid in it last night. It all...

    Yes. That was the engine off. It was raining and I couldn’t get up under it to really look. I checked with motor running and without. Running the level was at the cold mark. Off the level was the same.

    2007 4.8L Yukon: On the way home from work, I heard a “swshhhhhh” noise then lost all gears. 1-4 and Reverse. I checked the trans fluid level (warm engine, cycled gears, rested 10 min) still nothing. The truck doesn’t “feel” like it’s shifting into any gear. Just nothing. Topped off the fluid as...

    Busted Lines leaking Coolant. Help. Semi-stranded.

    Ok thanks! I saw a part on auto zone like a “U” shaped hose with fittings is that what I need? Just have them flow back into each other from the firewall hoses?

    Busted Lines leaking Coolant. Help. Semi-stranded.

    It’s night and this issue kinda caught me slacking, but it’s not the T’s. Those were replaced with OEM parts a year ago, the engine bay is dry. It’s just the passenger side is leaking in the middle of the vehicle and just recently the rear right in front tire. Again on passenger side. What do I...

    Busted Lines leaking Coolant. Help. Semi-stranded.

    What’s up y’all. So I bought a 07 Yukon today. 4.8L 2WD. It started to run hot, I shut it off, and pop the hood. Nothing. But on the passenger side, water/coolant is dripping from these metal lines tucked in the rocker panel that go down the length of the truck to the back. From what I...

    Chrome Black-Out'd bumpers

    I know this is an old thread but my 02 tahoe is white, and has had a black grille for a while, I really hate the chrome, it looks tacky to me, so today I’m doing this, will post results when I’m done.

    HELP!!!

    Well I just tested the TPS with a multimeter, and I’m not getting increased voltage with moving of the TB blade. I get voltage and ground, it’s just not increasing in voltage. Rescanned for codes and got a 0122. So I’m going to get another TPS and see if that’s fixes it.

    HELP!!!

    No spare TB. I’m pretty sure it’s the Holley. It made this noise the day I put it on. New IAC and TPS. Still does it.
  16. N

    HELP!!!

    No. I’m doing this in my yard. The idle without the IAC is about 600-800 with the IAC, it wil surge to about 1000-1500 then calm back down and the noise disappears. I think the reason it didn’t stumble was because of the position of the throttle blade, like it got just enough air to continue to run.
  17. N

    HELP!!!

    I did call Holley. No help. When I adjust the idle screw the noise will go away, during idle, if I crack the throttle it returns. Crack the throttle with the IAC unplugged the noise goes away completely. So do I reset IAC somehow? Measure voltage of TPS, then adjust the throttle blade?

    HELP!!!

    No I haven’t. I’ve just seen videos now recently of the “Sniper whistle” but it’s for a different unit than mine…

    HELP!!!

    this is where I’m at. With IAC unplugged, no noise. When you plug the port, or connect IAC it makes THIS noise.

    HELP!!!

    I’ve removed every single hardline and rubber hose checked for leaks. Didn’t spot any leaks. The sound only appears on first startup for a few seconds and then disappears after idle regulates. The sound is present when I give it gas, and when I’m downshifting coming to a complete stop. Sometimes...

    HELP!!!

    Ok. I used a cigar on the brake booster hose to see if I could spot any leaks. There where none. All hoses are practically new and in Good shape. The sound is coming from TB. It’s a Holley Sniper EFI #860008-1. The noise is coming directly from that. But there aren’t any leaks anywhere. I’m...

    Hello y’all I’m New here

    To be honest no, the ride was ok, but then I also have bilstein 5100’s and redone the front and rear control arms and bushings.

    Hello y’all I’m New here

    I had some 24’s on mine last year. I had the stock 17’s but they were ugly lol. So then I got the aluminum Chevy 20’s they looked nice but I sold them and I had a set of 24s. Got in a wreck (not my fault) ruined them, so now I have some 07 18s I think? On there now. They’re ok, but I think I...
