Q: Issues acceleration sometimes and gears won't shift

asked by on December 01, 2017

Sometimes when I push on the gas and my car begins to accelerate, it suddenly stops accelerating and the RPMs stop going up, but when I lay off the gas and press again, the car shoots forward. Also, often my car won't shift gears so I have to place it in paddle shifting mode and do it myself. Then after I've been driving it a while, it will shift again and occasionally not.

My car has 90000 miles.
My car has an automatic transmission.
