Hi all,

Yesterday my gearbox went into limp mode, was coming off a freeway and coasting to the lights when the car started shaking and up came the warnings on the dash. It comes up with P2534 - Torque Management Request Line A. On instruction I did full calibration reflag of the PCM & TCM ad left battery off overnight with the same issue.

Car runs without speedo & has 2nd/3rd gear only. Also on way in to work the horn sounded a handful of times and immobiliser fail came up on dash.

Any ideas?

I should mention the car is a completely stock 2006 HSV senator, e40 + t42
