I drained my transmission on my '96 SN176, with the PCM 1.23 Trans, and the tranny case, and my owners manual conflict with what I should run. I am sure the tranny case should be the right one, but wanted to make sure. My owners manual says to run 20wt oil, and the plate on the trans says to run DexII. What do you think? bonuts ------------- Terry |

Was the oil you took out red or brown?
Dexron III is what is recommended. If you took out engine oil (brown) then you might have to change it a couple times to convert to ATF. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

It looked reddish, maybe somebody ran 20wt at some point, cause it didn't really look like ATF

Maybe it was really old ATF. ------------- |

If it looked redish then it was probably already switched over to ATF. Follow the recommendations already given- stick with Dex/Merc or DexIII. Use conventional, do NOT use synthetic. Avoid high mileage formulations. ------------- |

I changed the fluid in the Classic over the weekend. It had looked red on the dip stick all summer. When I pumped it out it looked like old oil and I wondered if someone had been running 20W in it. I stuck a paper towel in it and it had a red tint. I'd say it was just really old tranny fluid. ------------- |

My model year 2001 SN 196 manual says to change the trans fluid every year but there is also a maintenance table that shows it should be changed every 100 hours.
Does anyone know which is correct? I'm inclined to change it every year as that should be cheap insurance. |

I think you should put 100 hours/year on your boat. That will end the confusion.  ------------- Play hard, life's not a trial run. '85 BFN '90 BFN White Lake, Michigan |

Out of curiousity why no synthetics?
As far as when to do the oil changes, when I talked to the local boat guy he said you had to change trans oil before lay-up because of acids that eat cluth material? Any truth to that or does he also have a bridge for sale? bonuts ------------- Terry |

Terry, The marine trans has nothing in common with a automotive automatic. No torque converter! It's simply a hydraulic pump to apply pressure to a forward or reverse clutch pack. I see no benefits to a synthetic hydraulic fluid even in a industrial application unless the system has been poorly designed with inadequate cooling and the synthetic is needed because of the high system temperatures. That's certainly not the case with the marine trans. I however do not know of a problem running synthetic. I'm sure Eric can elaborate. I think the guy is trying to sell you the bridge or he's slow and needs some work! Did he tell you how much he charges for a trans fluid change? Acids eating up the clutch? Eric? Ok guys, I've mentioned that it's was 29 years on my 312 without a tune up, well the Velvet drive has NEVER had a fluid change since I bought the boat. Doesn't leak a drop and runs fantastic!! Now, if he's talking about engine oil, that's a different story. Yes on a oil change before layup. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

IIRC, I believe Eric mention something about too slipery can cause a problem. Something about rubbing your hands together.  I bet he will chime in soon.

Pete, 27 years? Wait to you see how brown it is when you finally do change it. I guess you do like to keep it original! ------------- |

we must of been talking about HW and Quinn,
Pete, we think the same, I dont take care of *************** till it breaks, a matter of fact I know my car needs oil cause the light pops on in the corners, really, you dont eat the doughnuts when you work at the doughnut shop lol, anyways, once a season is fine, in the spring. transmissions dont produce any by-products such as acid, synthetics are not good on the clutch plates, in terms we can understand put your dry hands together as if you are praying, push them together and try to rotate them opposite of eachother...that is what normal oil will do, when you introduce a synthetic and do the same thing but this time adding a touch of hand creme, I'll let HW or Quinner finish this one ------------- "the things you own will start to own you" |

Bruce, The last time I checked it, was a couple days before I headed up to GL. Looked great - No signs of water, looked clean and smelled fine! I was waiting for the "original" comment!! ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I really dont know what the lifespan of Dex/Merc is, engine oil is subjected to higher temps and will break down under different conditions, in a trans there will be sediment that can float but it would have to come from an outside source unless something is starting to fail. you will see sludge in the pockets of transmissions, not alot most of the time with regular oil changes. but i never had to rebuild a transmission because of bad oil unlike an engine ------------- "the things you own will start to own you" |
