Was pulling out of work yesterday and the car felt like it was in 3rd gear. Stepped on the gas and it wouldn't really accelerate. Then it started crunching so I pulled off the side of the road and tried fwd and reverse and have no movement but there seems to be a load on the motor. Went to put it one the trailer today and it wouldn't roll in neutral. I had to go back and forth between forward and reverse and it finally loosened up. Any ideas? I'm thinking possibly spider gears diff pin? The trans has good fluid and normal vb mods. Lmk what you think. Wil probably be a week or two before I dig into it.
