Hello friends, I need help on replacing the little plastic gear in the transmission where the speedometer cable goes into the transmission.It is leakig fluid there right now. Someone please help me. Thanks.

You might need to replace the o-ring on the piece that holds the gear.

If that does not help, put a thin layer of RTV around the o-ring.
