I just brought my transmission fluid up to the specified level. I know our manuals caution about using "same type fluid" for compatability. West Marine sold me the "Dextron lll claiming it replaces the spec. in my 1988 manual. I believe it was Dextron ll that was called for. Am I OK or should I drain and refill?
Thanks in advance,

You are OK, III replaced II which replaced I. The "don't mix and match" basically referred to Dexron (any type) and ATF (the Ford-type) transmission fluid.
Ken : Stu is correct. Just don't put synthetic Dextron III in an old transmission that hasn't been using synthetic fluid - you may create leaks!. You can even use the Dextron III from the auto stores "for older transmissions". It's MUCH cheaper at the auto parts stores!!
Thanks guys,

I will give you my experience. When I drained my transmission last year, after just purchasing the boat, I would say that it had about half of what it should and was very black. My two cents says drain and refill. This year it is much smoother.
