My '85 just turned 155,000 miles (250,00km? ) and is on the original transmission. I changed the fluid around 150,000 miles and there was no clutch or other material in the pan or on the magnet. I hope it goes at least 200,000 miles before needng anything. I have the modulator set a little on the "firm" side to reduce wear. Sometimes the vacuum bleed valve and/or vacuum amp is a little testy, but no mechanical problems....knock on wood.
