This morning my car went to limp mode (not the first time). Usually, I restart the car and it goes away but today it did not. I notice this issue happens under very specific condition. 1. Early morning (when I first drive the car to work) 2. Going up a ramp (near my house), the gear jerks a bit and the gear light comes on. Asking for advice what to do. I read that need a transmission rebuild but any advice where is the best place to do this and the costs?
