ZF63A 2.1 testing 

Hi my name is Manny I have see some of your videos I just purchased a saltwater boat I am from Canada we recently dropped the boat in the lake it is a 2003 Four Winds Vista with twin 5.7 Volvo gxi motors it has ZF transmissions not sure of model the oil was a little creamy drained oil in both Transmissions and installed fresh oil did not change filters or even check filters 1 transmission seems to be working perfectly the other goes into forward or reverse and we'll stay under load for about a minute then Fades away stop spinning but if I shut off engine and try again it will repeat good for a minute under load and then slowly stops also noticed a little bit of air pressure when checking oil level on both Transmissions my question is the transmission that Fades away is it probably time for rebuilt or can it be something simple? Thank you in advance

Hey, what are your reasons for making ZF360A hot? I've done all kinds of things to prevent it from getting hot.
