Tonight while driving it would seem not to shift, mostly at slower speeds (I didn't take it over 45). I've experienced slipping before, but this was the opposite. The best I could describe it was like being in one of the lower gears (3, 2, or 1 - it's an automatic).

We've had the car for 4 years now. We've never had any work done on the transmission. We've been pretty vigilant about changing the oil, probably about every 4000 miles. Our former mechanic (we've moved) would occasionally fix minor issues with the car. It was given a tune up before moving.

Is it possible that this might just be low transmission fluid? Something else (not transmission related)? If worse case scenario, could someone ballpark the cost of replacing the transmission?

Thanks.

Hi,

first I would check the fluid level and condition, if it is low add as needed, if it looks or smells bad you may want to consider a flush, they are about 110.00 bucks and may help and if it doesnt, go from there, if you need some more help let us know, check the fluid while the vehicle is running at operating temp

thanks
