I don't think I fully understand your question? The odometer reads 189,000 and he's replacing the current transmission with one that came out of a car with only 70 - 90k? Or is it that he swapped out his tranny at about 110k and you're wondering how much life is left in the current one? Either way, the miles on the transmission aren't measured by the odometer at all, just the miles put on the car itself, regardless of how many transmissions you go through.
