    4L80E Stand alone kit


    Support FSC and see no ads! - Click Here
    hi guys im looking to put a 4l80e behind a 427 in my project truck. i heard there is a kit out there that allows me to do this without having a computer control installed? i really would like the 4 gears offered by the 4l80e but dont want to mess with all the sensors and computers.

    my other option is a th400, BUT it only has 3 gears. so i would like to have one more. thanks in advance!

    Re: 4L80E Stand alone kit

    There is a GMPP, TCI and other standalone computers that will comtrol teh electric 4l80e trans.

    there are also full manual shiftkits that will allow the use of teh 4l80e WITHOUT any computer at all. PATC offers a manual shift kit for sure.
    You have to shift this kit manually. If the selector is in 3rd gear, the trans is in 3rd gear, even at a stoplight. With the manual shiftkit, you will lose teh TCC lockup function however.

    I have seen teh TCI computers go for $350US on ebay before. These usually drive a 4l60e AND 4l80e trans.

    Compushift also makes a 4l60e/4l80e trans control computer is also in the PATC link.

    Here is some info from PATC The manual shift kit is about 1/4 way down the link. Its listed at $295

    Re: 4L80E Stand alone kit

    the whole manual shift thing would kinda suck so i dont think i would want to go with that option. i would really like to have the extra gear offered with the 4l80 but might just end up with a th400. seems like its going to get quite expensive to get a 4l80 up and running

    Re: 4L80E Stand alone kit

    You can also use a diesel 4l80 ECM, from 91-ish to 94, whenever they weren't electronic. I found a local one that is rebuilt, or go with a 4500....

    Re: 4L80E Stand alone kit

    what would the diesel ecm buy me? could the 4l80 still shift on its own like normal?

    Re: 4L80E Stand alone kit

    There was NEVER an NON electric 4l80e. Ever since they were used, since 1991 in teh trucks they were shifted electronically.
    The E of 4l80E, means electronically shifted.

    Re: 4L80E Stand alone kit

    I didn't mean not electonically controlled Imeant that they were either mechanically injected or it was controlled by an ECM, or turbo'd. All I know is that the early ones were like this....

    Yes, some diesels used a stand alone controller for the 4L80E, but they are no cheaper than any other one unless you get lucky at the salvage yard.

    Re: 4L80E Stand alone kit

    From the little bit of research I did a while back on the 4L80e I read somewhere that the '91-'93 diesels had the stand alone transmission cotrol unit. If you go that route you'll most likely want to tweak that computer as well. If I remember correctly Tunercat has a definition file available for the diesel truck transmission control module.
