  1. Chevy Silverado Forum (GMC Sierra)
    I've got a 2008 Silverado 1500 4.8, and my transmission fluid dipstick says it's overfilled, but I haven't had any problems with my transmission that would result from overfilling. What could be causing this?

    I have an 02 GMC Yukon with the 5.3. Throwing P1870 code. Started shifting hard between 1st and 2nd gear, will drive at cruising speed, then dies and won’t start. Took it to a shop, had to replace the fuel pump, drove fine and wouldn’t replicate the hard shift. 2 days later, it’s happening...

    Hello Everyone, The transmission on my 08 Yukon XL Denali is finally showing its age. Reverse has been slipping for a while but can still push her around on level ground. A couple of days ago my wife was driving the kids home from town and it acted like it went into limp. When I got home and...

    I have a 2005 Silverado 2500hd, recently I had a PO756 code come up, so I replaced the B solenoid which I assumed was causing all my troubles and the code to throw. After I replaced it and the filter/fluid I’m still having the same issues…. Won’t shift in D will shift up/down in manual once or...

    I drive a 2005 Silverado 2500hd with 176k miles on it, recently I towed a decently heavy livestock trailer about 500miles round trip. I did not exceed 65mph the whole time and the trans only got hot once,about 250°, when I noticed I slowed way down until it dropped down to 200°. This morning my...

    When I’m at highway speeds in my 2005 z71. When I let off the gas to apply brake for any reason then go back to the gas it revs up until it’s goes back into gear. For the life of me I can’t figure out why? The previous owner had the trans rebuilt it might have 20k on it. Anyone ever had this issue?

    I have a 2002 Silverado 1500. It all happened in about 30 minutes I started the truck fine but the transmission had no torque. I think it’s stuck in 3rd gear. I turned it off then turned on again and I had no prndl light or rpm’s and speedo. It works normaly if I hold the reset button. I parked...
  8. Chevy Suburban Forum (GMC Yukon XL)
    Hey all, I recently picked up a 2005 suburban about 5-6 months ago and have been rebuilding the truck so to speak as it seemed fairly neglected when I got it. The transmission was replaced about 40-45k before I got it but I’ve noticed that the 3-4 shift has been sluggish and slow to engage. I...

    2006 Sierra, 4.8, 4 speed automatic, manual 4wd, 200K. Started changing the transmission cooler lines and I ran into two problems. 1 the lower radiator fitting is corroded and one of the tabs that holds the clip broke off. Is this fitting easily replaceable? I already have the airbox out and...

    Figured I Cross post this as more of the truck guys have been into GM based transmissions I have a 07 bmw 328xi and it has the GM 6L45 transmission. First transmission had a slip bump which is notorious for the valve body causing the issue, so I did the sonnax zip kit and reinstalling I broke...
  12. Chevy Suburban Forum (GMC Yukon XL)
    2015 Yukon XL SLE, 5.3, 6 speed auto with 4WD and tow button, 124K miles. Never heard this noise until today. When driving constant 45 MPH let off the gas then moderate acceleration there is a sound coming from trans. Hard to describe, a groaning squeak, its short and abrupt. No slamming or...

    Our beautiful, new 2021 Silverado 2500 HD looks like it may be a lemon. The transmission needed to be totally rebuilt "better than new" they told us only 2 months after we bought it. Six months later it's towed in for a failed transmission again. Its outfitted to tow our camper trailer and...

    Hey Everybody, Got a bit of a weird conundrum you all may be able to help me figure out. For starters, I have a 2007 Silverado with a 4L60-E transmission. We had a really bad snow storm (at least for Oklahoma) this past winter. During said storm, the reverse on the 4L60-E suddenly stopped...
  15. GM Powertrain
    I've been having an unusual problem when coming out of reverse. The truck shifts beautifully off the line and doesn't miss a beat. The problem only arises when coming out of either my drive way or a parking stall. No issues going from park to reverse, however after shifting from reverse to drive...

    I have a 2004 Chevy Astro van 2WD 4.3L with a 4L60E automatic transmission and something is seriously wrong, but I have yet to figure it out. I definitely need some help. I usually do all my own repairs and I am very mechanically inclined, but this has me stumped. I even consulted a friend...

    So the past couple days I've noticed a weird knocking type noise around the 15-25mph range. It doesn't sound like it's from the engine but more like from the drivetrain, maybe the transfer case or transmission? The people i purchased it from had 3 22" rims an 1 20" rim. I know that with AWD...
  18. Chevy Silverado Forum (GMC Sierra)
    I currently have a 4x4 1985 GMC Sierra with a tbi engine that has a carb on it and a sm465. I have available to me an NV4500 and transfer case from a 92 6.5. And I could easily get my hands on a nv3500 if I needed. So my question is what all will I need to complete a swap to one of these...

    Hi. I've recently purchased a 2016 Silverado 1500 LT with the Z71 package and 3:42 rear end. The vehicle felt good during the test drive but I have noticed recently that it feels "restricted" in some way. I don't mean restricted in power, but more like the drivetrain is fighting against a...
  20. Chevy C/K Truck Forum
    Have a 1990 GMC 2500. Started running rough and stalling out, eventually wouldn't start. Had plugs wires coil and a module by distributer replaced and now it's running. Won't move and was told transmission is gone. However when it started acting up it wouldn't up shift out of first gear...
