My 02 Forester with 135K miles started to fail to accelerate at an equivalent rate to the rpms once shifted into gear and the clutch released. I think this is called “slipping.” I took it to my local mechanic who said the clutch was bad. $1,200 repair. Two weeks after the repair, the problem came back just like before. I took it back and this time they said it was the transmission, the viscous coupler to be exact. $2,600 repair. Four days later the problem was back. This time they tell me that the rear axle was slipping out of the differential because a clamp was loose and broken. The clamp was part of the differential and it had to be replaced. $700 repair.
Can anyone help me understand if they could honestly make this progression or should they have been better able to diagnose the problem?
Thanks for any help or guidance you can offer!
