Why would my car's rpms run high then return to normal after filling car with transmission fluid but then the speedometer stopped working?
I started to accelerate and noticed that rpms were running high. Returned home and
looked at transmission fluid. It was low so I filled it to level needed. Test drove it and it
started getting back to normal. Parked it and then later in the day, started driving it and
rpms were high again and now speedometer doesn't want to work.
