I have a Tohatsu 50 tldi with tilt/trim. Manual calls for Dexron II or III ATF to replenish low fluid level. I replenished the fluid with Dexron VI.Would mixing the two cause any damage to the pump,seals, etc.?
The seal went to leaking the next day and it quit working. Was this coincidence or did adding the Dexron VI cause damage?
