hey guys for some weird reason my r154 wont go into reverse:s? When i put it in reverse the car moves forward. Before it was installed on my 2jz it was sitting on its bell housing.. had to remove the reverse light and push the shaft back, so it could shift. The first gear thrust bearing is gone and I was just using this tranny to avoid towing it around when the car was functional except that 1st gear. It seems as though that reverse gear position acts as fifth gear, and fifth gear doesnt do anything. Any help is greatly appreciated.
