A couple of days ago I was rolling up to a four-way stop sign. The road was slightly wet and slippery, and there were four adults in the car. As I rolled up the car to my right had already stopped. I stopped, and waited several seconds for it to go. After a decidedly long wait time, I decided they didn't know how four-way stops worked, and started to go. Of course, they started go to at the same time, so I let off the pedal. At the same moment, they hit their brakes as well, so not yet having come to a complete stop from the first attempt to go, I decided to just step on it and go. As has happened several times recently, my diesel decided this was the moment to hesitate (call it turbo lag or just computer brain-fart, whatever you want to call it), so I continued pushing down further on the pedal. Once it finally did go, it pulled hard, spun the wheels slightly on the wet pavement, and I couldn't quite tell since I had the radio on, but it felt like there were two or three hard bangs as it slipped and finally took off.
Was this the tranny slipping, or did I maybe just imagine it when the tires slipped a bit?
