    Default I lost 3rd and 4th gears in my truck need help!

    I've been without my 3rd and 4th gears without my trucks for two gears on my truck for two days now, just been busy. It went out with a quick spinning clutch and took out two gears. It will try to shift to 3rd when in Drive but it will just start bucking. So I now have a 4.8l getting less than 12 mpg. Anything and everything will help. I've been wanting to get a slam shift kit for my truck or something that tough due to my past transmissions. Thanks


    Just Affording Gas :D

    Sounds like something broke like the 3rd clutch hub maybe. It could also be a control problem. Have you checked the trouble codes? You need to take it to a transmission shop and get it looked at.Driving it will only make the repair more expensive.

    First Gear uses the low roller clutch and the forward clutch which stays on in forward gears.
    Second gear The 2-4 band comes on.
    Third Gear. The Band comes off and the 3-4 clutch comes on.
    4th Gear. The 2-4 band comes back on and the 3-4 clutch stays on.
