Mk1 Ultima Rev Counter /gear Change Problem

[rsmuppet]

Hi there , i'm after a bit of advice brfore i go ripping the car to bit's to find the problem , I have a 1999 galaxy ultima (2.8 auto ) . when it rains or i wash it the rev counter starts to play up and usually bounces around between 2/5 grand. Now this in it's self isn't such an issue as i don't drive it that much only the missus , but it appers to effect the gear change and will hold the box in 1st gear . I'm hoping somone has come accross this problem before . Cheers Al

Hi there rsmuppet

I don't see whats so funny with your post perhaps I'm missing something here but welcome anyway.

Only thing I can think of which may help is the transmission control ecu is located on the right hand inner wing panel by battery, this will be exposed to rain and vehicle washing as water can run freely under sides of bonnet, check wiring and plug there may be corrosion in the plug or dodgy wiring, I'm sure the plug/ecu has a link with engine speed control, "Mirez" will probably confirm this
