One day last week when I was driving home, it suddenly felt like not all of the power from the engine was transmitted to the wheels...
( Even if I pressed the accelerator, the engine would rev up but the car wouldn't move faster )
Thinking that the transmission might be busted ( as it happened with my previous car , an old Olds 88 junker ), I pulled over and checked the transmission fluid. That was ok, as I had that changed just a couple days before that.
I got back in my car , and I was prepared to try to drive it home, even with the problem.
Funny thing is, it didn't do it anymore, and hasn't done it since?
What could it have been?
