Having forwards and reverse engaged at the same time wears out the forward clutch (the A clutch).

Pretty sure I killed mine towing. Didn't know about using 3 instead of D. Simple 'fail to proceed' after a period of M + S flashing occasionally.

When it was "rebuilt", it failed again in less than 1000k. Symptoms included a situation that I could only describe as being like a manual with two gears engaged at once, so maybe those seals you mention were faulty. Before that happened it would change erratically or not at all unless I pushed it.

When it was pulled down again, there was this. Might explain the erratic shifting?

The teeth on the clutches looked similar. The A clutch, which was the only thing the "rebuilder" replaced, was totally shot.
