    4L80E Into VZ Commodore

    Hi there, was wondering has anyone done a 4L80E Swap into a 2006 VZ L76 SS, E38 TCM..I know cant do a segment swap but can anyone shed some light on the speedo adjustment ie ISS/VSS...I think box has to come out due to no reverse etc...Is it true the amount of solenoids the 4L80E has/uses is less/different than the 4L65E?...Tried Speartech for a harness/speedo ext etc but to no avail no application for out vehicle ..If anyone could shed some light on this it would be much appreciated Cheers Bret@ultimatelsxtuning

    pretty sure all your going to need to do is re-pin the round connector on the trans so it activates the correct solenoids.

    The only thing I'm not sure on is whether or not you will require the ISS signal, probably just a matter of turning off some dtc's, but from the looks of some diagrams the 4l80e does have the ISS

    I've just re-wired a vz e38/t42 combo so I can convert it to a 6l80e gearbox.

    Be interesting to see whether this works - tried VZ OS with T43 a while back and no luck.

    Good luck.

    my combination will be a bit special. lol. it's going into a vy. So I've also got a vz pim to wire in /translate the CAN data to ALDL comms for the dash cluster. I've got the original vz ecu along with some later model e38 ecu's I can try. From looking at wiring diagrams/schematics etc it all looks doable. just finding the right OS combination will be key.
