    Can't read transmission for 2018 Challenger?

    I'm trying to read my transmission on vcm editor but it doesn't let me. When I read normally and go to the transmission tab, it's blank. I'm trying to read only my transmission but I don't even have an option for that. There's no way there's no transmission options for a 2018 so what am I doing wrong? Thanks!

    Can you post a screen shot of the VCM Editor when you try and read it?

    You have to select the hardware. What version of the software are you using

    I'm pretty sure hardware was blank as well, I'm using version 5.0.4

    I believe ZF 8HP requires four credits (normally).

    When you say four credits do you mean I need to buy four more credits for that itself or just two more since I already have two?

    I would believe all 4 credits need to be addressed to the correct/same controller (which is ZF 8HP TCU).
    Once another 2 addressed, it should work. If not, maybe get in touch with hp tuners support service.

    Look at "DODGE/CHRYSLER/JEEP/RAM TRANSMISSION CONTROLLERS" => "18-23 ZF8HP2 8-Speed Transmission Control Module (TCM) 4"
