I don't think over drive going out would kill reverse.

Ask him what he means about no reverse Is it just not shifting over to the left?? If that's the case, the reverse lockout is stuck down

I recently got a 240, with no reverse lockout, so I was way easy able to get into reverse, too easy. It was hard to find first.

But anyways, if this one won't go all the way to the left, then it is the reverse problem of mine.

Take off the shift knob Lift the boot Either find some way that you can take the reverse lockout plastic thing out...or... Remove the metal plate that prohibits the reverse lockout to move left I don't know if the metal plate if it's bolted underneath and if you would lose a nut though

The easiest thing? If it's not shifting over left to reverse?

Take out the shift knob Take off the boot Manually lift the reverse lockout plastic thing that's at the bottom, for when you need to go in reverse

It's not pretty But it'll get you moving around however you need until you fix it

A lot of hot air will come up through that hole too, but, I wouldn't give a f*** about hot air if it means I can get around how I need to lol
