Just had my tranny rebuilt w/ a quaife lsd installed. Installed by a honda tech at a dealership. Anyhow, have about 400 miles on it. All of a sudden, it won't go into first or second. It goes into all the gears when the tires are off the ground, but not when there is load on the tranny. I took the small block thing off where the cable linkage goes. I put the tranny in first gear and put the block back on. When I put the car to the ground..it shifted perfect. Went for test run, and it happened again. Any idea what the hell this is. Anyhelp would be very much appreciated. Chris
