q240z Posted December 1, 2022 Share Posted December 1, 2022 I've got a 2009 Forester with 150k miles, non-turbo, and automatic. After coming to a stop at a stop sign, I started to accelerate, heard a noise, the engine revved but the car wasn't accelerating anymore. Just enough power was getting to the wheels that I was able to limp the last mile home. On downhill slopes I could coax it up to 45, which helped get over the uphill slopes. IIRC, the sound wasn't a BANG...more like dropping a hammer onto asphalt from 6" high. Maybe a 'thud'? Once home, I jacked up one rear wheel with the parking brake off and the transmission in Park. I was able to rotate the wheel and could see that the driveshaft was turning. I don't think that should happen in Park. When I let the car back down, it started rolling forward despite being in Park. I reset the parking brake and jacked up the front end. Both wheels rotate despite the transmission being in Park and the rear wheels on the ground. But rotating either wheel doesn't cause the opposite side wheel to rotate. CV joints appear fine. There's no slop in the axles or drive shaft, and there have never been clicking noises when backing while turning. Transmission fluid is up to the FULL mark. I set the car down, started the engine and worked the gear lever. Drive and reverse gears feel like they engage normally, but the car barely accelerates regardless of throttle position/engine RPM. At idle it seems pretty much normal. With the brakes on and the car not moving, I shifted to Park and there was a whirring or clicking sound for a second that then stopped, as if the parking pawl wasn't engaging. If I let off the brakes with the car in Park, it rolls as if it's in neutral. I'm stumped. Thoughts on what might be wrong? Quote Link to comment Share on other sites More sharing options...
