722.6 Gearbox jerking

[meri_gadi]

hi there all...

I got a new Box fitted recently.

Recently the Gearbox is jerking when the car is De-Accelerating or Accelerating on the kick down.

What could the problem be??? any ideas any1.

Could it be mechinical or electronic

Get the codes read, it sounds like a speed sensor fault. It could be either the electronic plate or the gearbox ECU.
If it didn't do this before then suspect the new gearbox.
