If it were any other gear than reverse, I'd say it was a worn selector fork. But reverse is the one that normally wears least.

There is a reverse stop on the gearlever housing. Might be worth checking that is set correctly. There's a bit about it in the standard workshop manual.

Mine kept jumping out of reverse I had to hold it in gear when reversing, fitting HD driveshafts and ARB's and going offroading killed it...hope yours aint that bad. I've put a R380S in mine now

I've got the same problem..If the reverse stop is set correctly its a rebuild or replacement box I'm afraid..I'm trying to save my pennies for an ashcroft one
Hit it till it breaks then hit it some more !
