2004 Subaru Impreza WRX 4 Cyl 2.0L
Transmissions & Drivetrains
I'm having trouble accelerating in my vehicle.
The car has about 150k miles on it and I recently had the serpentine and timing belts replaced.
750 good , slipping bad. Means transmission is wearing out. You could try some additive like no-slip to see if helps and to diagnose. Not a cure though. Could be ready for a rebuild.
