I have a ford tarus 94. It has about 160k miles on it. It has some Transmission problems and here is what it does. When I am on the freeway at higher speeds, sometimes it suddenly jerks down to a lower speed. It is as if suddenly the gears shifted to a lower one and the car making a bad sound etc. I have to let the acceleration go and let it come back to a lower speed. The mechanic suspects, it's the transmission filter.
I read some other posts here and some point towards the VSS. Also incase I need to get the transmission changed, what would be a cheap place to get it done in MA or if needed in NH. I live around Boston.
