There is no fault lights on, when i drive it slow, around car parks etc its fine, but on the road its slow to change up and wont go into top gear ( possibly the last two gears !) it just does not seem right.

before you scrap it or spend hundreds on an ecu, have you tried an autobox fluid and filter change? can work wonders when the box is playing up and is alot cheaper than just replacing parts in the hope that it cures it

Definately worth a go - filter kits can be found on ebay for about 20, then get yourself some fluid and crack on - amazing the difference it makes.

Sounds like a sticky govenor. Can be helped by changing fluid and filter. But not always. You could try changing filter and fluid, running car for a couple of weeks, then changing fluid again. Keep changing fluid until it is absolutly clean. As there is always 4 litres or so fluid left in you cannot drain.

Maybe you should get the fault codes read, maybe it's in "Limp Home" mode.

i have come across a motor and the leds under the gear position were not lighting up and it was stuck in third gear carried out a ecu test found no comms but tested all the wiring and it was a fault in the becm not allowing comms though did find the gear position switch fault as the engine and display take signals before the becm and gearboc ecu fitted new switch 290 set it faults with lights cleared and all was well.

early warning of switch faults are non dip of mirrors in reverse and sluggish changes
get ecu read

I had similar problem with gearbox and changing of gears, at the end it was the Kick back cable that stretched. Fixed it and seems to be fine now...

Maj

Where did you get the cable ? I have really stiff gear change and suspect this may be a contributing factor.
