  1. Chevy Silverado Forum (GMC Sierra)
    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?
  3. 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...

    I threw a rod and blew the 3-4 clutch pack in my 95 I acquired the engine and transmission both working from a 98 they're both 5.7 l I've got the 98 engine and transmission installed.

    Ok so I'm new to chevys, new to California and this is my first rebuild. I got a 95 chevy k1500 Silverado 5.7L V8 350 with TBI, taking old motor out, still runs but want a bit more power.

    My 2003 5.3 Silverado has no cats and a thrush welded muffler. Recently I had to drive a long distance so I replaced the Thrush with a stock muffler. After the trip, I put the Thrush back on, and the drone is much louder and a lot less bearable than before I reverted to stock. The only...

    hey y’all, I bought an 03 blazer with the 4l60e a couple months ago and after a week of driving the tranny started giving me problems. I know a little about mechanics but I am clueless when it comes to trannys. Everything was going smooth until I pulled up to a stop sign went to take off and...
  10. Chevy C/K Truck Forum
    Thinking about ditching the EFI and swapping to a carb, my only setback is the 4L60e. As far as I know the only things I need is a Holley carb and throttle position sensor kit, HEI distributor, matching intake for heads and carb (edelbrock performer 2104) and a fuel pressure regulator with the...

    Hello everybody, I have done a lot of research on how i'm going to make my LS1 fit into my truck. It's a 1994 k1500 regular cab short bed. The only thing I am having trouble nailing down is if my 4L60E (original to he truck) is going to bolt up to the LS engine or if I will need an...
