  1. 1994 Chevy 1500 - Doesn't Move Forward On Its Own When in Drive

    Hotrodding Basics
    Hi All, :welcome: Quick question: when I put the transmission into drive and take my foot off the brake pedal, the truck never moves forward under its own power. It takes a bit of pressing the accelerator pedal to get it going, but I assume that's just because it is a big heavy vehicle. Is...
  2. 4x4 from a '85 700r4 fit a '94 4L60E?

    Transmission - Rearend
    I have a '85 K5 that came with a 305 and a 700r4 with 4x4. I recently picked up a 350 from a '94 blazer/suburban/Yukon, etc. (Dont know which exactly, got that from the casting numbers). The new 94 engine came with a TBI, instead of the 4bbl I have on the 305, so it has a pcm. I want to keep...
  3. 4L60E Screeching in Manual 3/2/1

    Transmission - Rearend
    I've been searching with zero luck for days on this one. It seems there are some experienced 4L60 mechanics here so I thought I'd ask and see what turns up. Vehicle is a 2000 GMC Jimmy 4x4 with the 4 button "soccer mom" auto 4wd. I'm currently sorting out issues with that, but believe my...
  4. 4L60E Won't start off in drive

    Transmission - Rearend
    Thanks for any help I get with this to start off. We have been messing with this truck for over a year now and have a problem with the tranny that's confused even our GM cert son in law. I have a 2000 Tahoe 4x4 with a 4L60E. Last year I lost second gear. So we had our son in law rebuild...
  5. 1994 Chevy C1500 - 4L60e Only Shifts/Stays in 4th Under Acceleration/Load

    Transmission - Rearend
    Hi All, About a year ago I asked for some help regarding the 4L60e in my '94 Chevy 1500. I have been having issues with getting it to shift into 4th. At times, it prefers to bog between 3rd and 4th. I replaced the TPS, along with the temperature sensors and they seemed to have helped the...

  8. 4L60E fluid return into transmission

    Transmission - Rearend
    I exchanged all my fluid in my 4L60E by removing the return hose off the transmission cooler and adding fluid down the dipstick at the same time while the engine is running. It was always within half a quart plus/minus so I don't think there was any problem there. My question is, a friend said...

  10. Rebuilt 4L60E, no 2nd or 4th, can't remove 2-4 servo cover

    Transmission - Rearend
    I just rebuilt a 4L60E for a 1999 Astro van, AWD. While rebuilding it, the 2-4 servo cover was so badly corroded, I couldn't get it to move at all. I whacked on it with a block of wood and a sledge hammer, tried compressing it with a long bar clamp, spraying it with cold spray, used a pipe...

  20. 4L60E check ball capsule leaking

    Transmission - Rearend
    I tested the check ball capsule by pouring parts solvent through the passage. I did have a steady stream of solvent leak thru to the inside of the case. I am under the impression that there should be no leakage at all if the capsule is working. Called one trans shop to see what it would...
