Thread: ZF8 Trans lock

  1. #1

    ZF8 Trans lock

    So i was able to get transmission to shift into 2nd while brake boosting but it would not hold 1st at same time. You can see in log every time solenoid E engages C releases any thoughts on how to get them to both stay engaged? Trying to get it to act like the dodge trans lock where it will engage 1st and second at 0 oss when the shiftlever is held and APP is 100% and then release sol E(2nd) as soon as the lever is released.

    Hey so you want to "launch" in 2nd instead of 1st? What do you mean by holding the shift lever?

    Cool stuff!

    No i want a transbrake function. I don't know how to explain hold the shift lever anymore simple than that.

    That's going to require some customized software for the transmission controller

    being that dodge already offers it in the ZF would be nice if HPT would add the functionality into the zf definitions.
