Just installed a new tranny for this mower. Same exact fit...followed the little videos from Honda, also installed a brand new Smart Drive cable. Everything went together fine, no problem installing cable. When I started up the mower, I cannot get the smart drive to work. Doesn't matter where I adjust the cable...I cannot get the rear wheels to lock up when pulling backwards no matter where I adjust the cable! When I start the mower, and raise the rear wheels, the wheels turn but when you put them on the ground, the mower won't move. The drive belt was in good condition... Robert, I was told to send you this message from another member...thank you. HRR2167VKA - MZCG-9309415
Figured it out! I had the drive gears in backwards. It now goes forward...however, I have a brand new cable installed and I have to screw the cable out quite a bit to get it to drive properly. Same problem with the old cable! So, is there any adjustment other than the cable adjustment?
