Firstly Hello! My autobox has developed an odd glitch, when going down any hill (no matter how gentle),if I touch the brakes when I'm doing anything over 45mph it changes down a gear slight pause then drops down again. Depending on the speed I'm doing this obviously sends the revs stupidly high. 9 x out of 10 if I then blip the accelerator it changes up again. Has anybody come across this before? Any ideas if it is a software issue on the TCM or a Mechanical issue in the box itself? TIA (its the 204bhp built 06/03)
