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
