Hi, I have 2004 honda trx 400 and the heel-to-toe shift level is no longer engaging into the clutch mechanism and therefore not shifting gears. My model appears to have a different heel-to-toe lever in that instead of the clamp with nut at the bottom attachment point it has a post that is attached to the heel-to-toe shift level. The post goes into a 1 1/4" pipe (lack of proper words), 5/8" diameter. There are cogs on the post and my guess is the cogs on the post and cogs inside the pipe are warn.HEEL TO TOE Gear Change Foot Pedal Shift Lever for Honda TRX 400 450 S ES Foreman it's not exact fit for your model, but just to show you some are available.
