ATF 89 28 ft express

Port Transmission has a small fluid leak . But it's time for this seasons fluid change. What ATF do you suggest. I have 1,200 plus hours on the engines.
Thanks Steve

Check transmission manual. I doubt it's ATF, My Twin Disk use 40 weight or diesel engine oil.

thanks for the reply.
its a velvet drive. i know its a ATF. I was just wondering if a specific type would help with a leaking issue. A high mileage or something. i know cars have a fix a leak. i have not considered or tried anything like this. A buddy of mine has a car repair shop - he is a fan of the Lucas products.

Velvet Drive Use any of the Dextron I , II, II etc ATF

I change tran fluid every 50 hrs. I pump out the dip stick hole. I do not drop the cooler. Changing every 50 hrs will keep recyle it through without dropping and draining lines. IMHO additives for leaks are a poor band aid fix if any. They can cause more problems to these reverse gears than any small leak!

Dave is correct (of course). Dextron III is what manual calls for. Uses see as my Toyota Tundra..
Convenient for me buying the same fluids I would not put additives in.. A small leak is no problem.. Just Ck your fluid and put a soak pad under it

dextron iii
should I use a "high mileage" style or just a regular major brand like castrol
