Transmission fluid

[Brian1045 28]

I just completley drained my 3 speed tranny. Now that it's almost 2010...Is there anythng out there now days you all recommend to put back in it?

Any space-aged suggestions on tranny fluid?

Also... I have all the manuals that came with this WH, but I'm not sure on the capacity. It isn't listed

in advance!

WH's lube manual recommends 1 1/2 qt.s of SAE 90-140 A.P.I. service GL-5 gear lubricant in your 1045.

thanks Linen.....I have plenty of the 90 weight around, a quart and a half it is!

Brian,

I'd try the extreme duty Mobil 1 85/140 synthetic or Castrol's Syntec in the same weight , they make an amazing difference when cold and seem much less prone to breakdown when hot , I use them both in my offroad truck and have had excellent results despite a lot of grave abuse .

I am sorry to post contradictory information but in this case I believe that it is warranted.

if you have an old tractor that has always been running dyno oil (non-synthetic) then it is a good idea to stick with a dyno oil. I say this because the seals, o-rings, and various other porous rubber components get saturated with the dyno oil. When switching to synthetic witch has fancy new detergents the synthetic oil cleans the system it is now in of the old dyno oil and emulsifies it and traps it.

It tries to do the same thing with the dyno oil that is saturated in the seals. Eventually you will develop leaks because of this. I have heard people saying that they switched over their vehicle at 100,000 miles and had no problem

Good point , aged seals can sometimes be a problem . In my stuff it's never been an issue but doesn't always work for everyone , just depends on wear . The one thing that synthetic will do very well is prevent wear , something the dyno oils cannot beat . To my equipment , the difference between using dyno oil and synthetic is a matter of choice for what works the hardest , things that do not see heavy use or high heat get just good quality oils . I've been tempted to try a good synthetic hydro oil in one of these older vane type transmissions just to see if it helps them perform better but hate to lose one because of an experiment .

I noticed I am getting a small tranny drip from my main pully coming out of the rear. it's only about 1-2 drips a day...No biggy, new fluid not old enough I guess.. :banghead:
