My husband is WONDERFUL with the older stuff but we are lost on the new stuff.
Sometimes, it seems when it is cold, it won't shift into overdrive. Then when it is warm or when it feels like it, it shifts just fine. It also will slip sometimes too. We both figure it is due to get rebuilt but am hoping there is a little trick we can try to keep it alive for little a while longer. Any suggestions or help would be apprecitated. Thanks! :confused: | | |

The 4L80E is a heavy duty electronically controlled transmission, the E.C.U. [computer] has to be able to communicate with the engine E.C.M. [computer] and all of its sensors, or problems like this may occur. I would take the vehicle to a shop that can download any codes from either computer, if there are no codes then I would take the vehicle to a transmission shop you trust and have them diagnose it, hope that helps. | | |

We figure that is the next step to have the computer checked out but I just would love to get rid of it. I hate computers, sensors and all that junk. I wonder how difficult they are to rebuild. I have done a turbo 350 with help. I figure you would need a medical liscense to tear into this one.
Anyway, thanks so much. I guess I will just have to break down and get someone else to do it instead of us. | | |

Cleanliness is the most important thing when rebuilding any tranny, good luck. | | |
