    Just got my tranny installed and car seems to run and drive fine bar 2 things. I'm getting DTC's P0700 and P2764. TCC pressure control solenoid low voltage. And my traction control says its needs service. I've checked and cleaned all my connections and couldnt find any frayed wires or bad connections. I'm at a bit of a loss. Or can this be caused by ground wires? I think when I put the tranny back in 4 ground wires ended up sharing the same spot. Idk I need some here, please.

    this a used tranny? or a rebuilt unit by the shop?

    Owch. This is why I refuse to just "fix the one issue" and bolt it back up. I always at bare minimum replace all clutches, inspect, and replace all solenoids. All solenoids are something like $80 so it's cheap insurance against having to rebuild it down the road. At that point, an entire master rebuilt kit is only $500 including the solenoids, so I almost never do a partial rebuild for this exact reason.

    Glad to hear they are taking care of it though. I know installing these transmissions are a pita so I feel your pain having to pull it again. At least you can save money there!

    Mmm feels good to have the GXP back, and it runs great now. Sadly the traction control lights are still screaming at me. I'll figure it out. Eventually
