I have a simular problem on my 2000 mgf steptronic

[trevor]

my one goes off from start quite nicely but get up to 55 mph it goues into
limp mode and engine speeds up to 4500 revs
if i stop imediatly turn off engine it goes back to normal but i have to keep
it belpy 50 mph
the car had a new steptronig cearbox fitted in 2009
since then the car has ony travelled 500 miles
i ger a code next to the mile meter with f d flashing when driveing
iv had this analyised and been told its the code P0722 which indecates the
speed sensor
iv taken it into an old rover mg dealer in canterbury and they are fitting a
new one tomorrow at a cost of 350 mind you they have said there is no garentee
that it will cure it.
What do you think anf further idears please.
regards
trevor
