So I just got a 2001 Subaru 2.5 rs with a ej25 and auto trans. Had the engine replaced with about 50k also the tranny was replaced not sure the mileage, then the tranny ran well for like three months then started running rough. When I come to a stop and then try to accelerate it won’t accelerate and i step on the throttle while the car sounds like it’s choking. Once it’s running it shifts rough and hard. Only light on the dash is the AT oil temp light. I’m confused as why it does that. Mostly it tries to stall at stops. I’m pretty new with subies. I appreciate all the help!
