06 Merc Mountaineer - Trans seems to search for the right gear between 5, 6 & Overdrive.
When travelling on level road at between 45 and 60 MPH the car vibraates for about 1-2 seconds like it is going over a rumble strip. When this happens, I have noticed the tach moves up and back down ever so slightly. At first I thought it was a tire problem but now I am thinking trans. Anyone else experience this?
I would check your trans fluid level. If that's ok then have it flushed. BG is the brand that I highly recommend.
Turned out to be a trans problem that was corrected by flushing. Thanks.
Oh good to hear.
Only way to check the fluid level in this car is to pull a plug from underneath the car. Not having a lift, I took it to a shop and they added some fluid which fixed the problem. Thanks for the input.
