  • 4L60E starting to hesitate going into 3rd gear

    I am thinking that my 3/4 clutch pack is starting to go.
    I used the internals out of my fresh V6 transmission in the V8.
    I am thinking maybe the extra power was too much.


    Sound like the 3/4 going to you guys?
    Best replacement for street use with decent power?


    Any input is appreciated.

    From all the reading I've done, I've gathered this:
    Avoid Alto
    Borq Warner High-Energy work great. I will be using these.
    Late model OEM work well.
    Raybestos Z-pac still have people leery, but I've seen a lot of builders say they are just as good as the BW. One sided clutches.
    Raybestos Blue Plate Specials are good on the strip, I guess they wear out on the street

        Should I do anything else?
        It's basically all new inside.
        Beast shell
        New steels and clutches
        Corvette Servo
        HD2 Shift Kit


        I was thinking about throwing a wider band in when I pull it out,
        opinions?

          put a new reverse drum in there if you go with a wide band

            I noticed that it is a lot worse at light throttle.

            Under more throttle it seems fine.


            any chance it's something else?

            It isn't slipping in gear, but it seems to stumble into gear

              This sounds very similar to Brian's old '93. I drove it when Davy was selling it - and the 2/3 shift under lighter throttle was very hesitant, as you said. Wasn't slipping per se, but it just took a while to get in gear. Under a heavier foot, it shifted just fine. And Brian had that trans rebuilt before he sold the car, so it was a recent rebuild...

                I'd install a line pressure tester just to rule that out first. It could be a dozen different things internally - clutch clearances, servo travel, partially blocked hole on the plate, fluid leak in the circuit, etc, etc

                  before mine died completely, it wouldn't go into 3rd at full throttle. At light throttle/normal driving it drove perfect. When I got my tune done, the dyno killed it but good.
                  When in doubt, Whip it out !
