D range in need of repair? Not terrible but there is no such thing as an inexpensive fix here.

Shift linkage moving all the way and is holding the transmission in gear ?

D range shift collar and teeth are dubbed off,, happens when you get out on the road and shift up to D while rolling,, My Dad would dub ours off every couple years,,he couldnt hear it grinding...it is a big job, final drives come off and strip the case, all but the counter shafts needs to come out.

like others said someone was rolling and trying to jam it into D range. I had same thing happen to my 8430. If you don't have to travel far with it you can just use C range.

Bungee cord between sound Gard body and lever can get by for a long while. BTDT on a 4430

You can hear an echo in the case when you begin reassembly
