1996 Avalon mud problem

Got stuck in mud. At first it would only go forward in all gears except reverse(nothing) and skipped a lot in first. Now… Automatic gears all work in forward. Park is now normal. But neutral goes forward still and reverse does not go at all. I cleaned the mud off and am considering flushing the tranny fluid.

Shift linkage probably got mis-adjusted so you’re not really in neutral or reverse when you place the shifter in those gears.
