Is anyone using anything other than +4 in their t case? reason I ask is I seem to remember having read somewhere that people were using 10 weight oil for greater lubrication.
When I was still in high school I worked summers for a company refacing the military housing on Grand Forks AFB. Some of the local workers and I ( I am from WA) went to some 4th of July festival in Red Lake Falls back in about 86 I think. Good times. Beautiful country up there in NW MN. My Dad's family is from Ada and Halstad.Yup, it's been known to get cold up here in NW Minnesota.
That is a good question, what is best?Note / run what you want or what the "factory" says , but how can the same weight oil with better lubrication not work better than the atf
Everybody says you need to worry about the chain, I have only seen two 208's destroyed from lack of lube, they both had the planetary gears gone.A typical planetary gearbox has several load bearing elements which are in relative sliding motion to each other which causes heat to be released. The major sources of friction as well as heat are the meshing teeth between gears (sun/planet, planet/ring), thrust washers, thrust bearings and needle bearings. The lubricant performs the vital function of both lubricating these sliding interfaces and cooling these sources of heat, thereby preventing failure of the gearbox.
That is a good thought. The trans & transfer assembly going down the assembly line in the trans plant, Both get the same fluid, that eliminates the possibility of the wrong fluid in the trans, and makes it easy to stock one fluid. Manuals trannys were made in NY, and shipped whole, so they were likely already topped off. Not sure how they did it in the 70's & 80's, but in 2000, they assembled the engine/trans/ & transfer into a unit, and shipped them to the assembly plant as one.I think the biggest factor for atf being chosen is to eliminate the possibility of cross-contamination with an automatic trans - should input/ouput seals fail.
