got rev. no forward

There is a thrust washer under the cone gears in a standard bravo..when that thrust washer breaks you lose forward and usually not reverse...simple washer replacement should fix you up..but check your cone gear floor..sometimes a crack in the floor is what makes the washer break.

The floor of the gear is broken buy a gearset and seal kits.
