hi planet- you seem to be very knowledgeable on the m40 trans. the key with working with my model a 5 speed m47 92 245 is anticipating inevitable common breakdowns and thinking out an alternative plan b when the first plan craps. the m47 so far works normally and shifts ok. during long drives it gets a little stiff shifting and feels tighter shifting. cant find anyone experienced, knowledgeable and not a shyster to rebuild an m47.also cant find a used but good m47 in yards here . these guys are like finding a typewriter repairman. gears make no noise. suspect gearshaft bearings are getting worn. oil level ok. dealer says he has them but wants billions. use car every day around town but hesitant to use it on long trips. dont want to be marooned in stinking creek surrounded by clip joints. what think you? thanks tons oldduke
