[AT] Transmission/Differential Fluid

[Dean VP]

Dudley:

I don't remember the thread about using transmission fluid in place of 80-90
weight Gear lube.  But since I have to use so much of the 80-90W stuff for
the large cavities in the old JD's I have searched around a bit to find some
reasonable priced stuff. The JD and Napa 80-90W oil is just too expensive
for the quantities I needed. 

A few years ago I found 80-90W Gear Oil at the Costco in Yakima, WA in 5
gallon containers. I immediately bought several containers. I don't think
they sell it as 5 gallons however, I think it's by weight. Some odd measure.
I hadn't seen it at our local Costco's in Everett or Kirkland but I have
since discovered it at the Mount Vernon, WA Costco which is one heck of a
lot closer than Yakima. As I recall the container sells for $23 to $27. I
just don't remember the exact price now. That is less than half the price of
JD's version. I suspect I/H dealers have a similar high price. 

I know this doesn't answer all of your questions but it is the most
reasonably priced bulk 80-90W oil I have found locally. I have it in all my
tractors w/o any problems so far.  $5 a gallon is sure better than $12 a
gallon. I suppose if one bought it in a 50 gallon barrel one could do even
better but I wasn't willing or ready to deal with those issues.

Subject: [AT] Transmission/Differential Fluid

I seem to recall - it has probably been a couple of years ago now - a thread
on transmission fluid versus gear lube in the transmission/differential of
older tractors.  While I know the manuals generally call for 80-90 wt gear
lube I seem to recall that some/several on the list indicated that they were
using automatic transmission fluid instead.  A couple of weeks ago I drained
the back end of a Farmall M - it definitely had thin, red looking fluid in
it.  I am now ready to refill and am thinking of using transmission fluid
instead of gear lube.  While I have drained six or seven tractors before I
have never yet refilled with transmission fluid.  So, I am curious - the
last time any of you refilled the back end of an old tractor (I have a T035
so know Ferguson's need a special/unique oil), did you use transmission
fluid (and if so what kind) or did you use gear lube?  I don't recall but
does anyone remember any drawbacks being noted from using transmission
fluid?

Thanks -
