Short Term Syn Tranny Lube Report

Randy G.

You all remember my nightmarish ordeal getting the fill plug out of
the M47 tranny. The plan was to remoive both plugs and replace them,
using synthetic tranny lube. Nowhere in my area sells the Redline
product for the tranny so I bought the Mobil 1 product for this
purpose.

With the drain plug out I swabbed out the bottom of the case to get
out all the crud I could (that blackish/greyish slime) and with the
left side of the car jacked up (and supported on a stand!) I
overfilled the tranny just a bit which is said to help these boxes
last a lot longer.

I took my first drive with the new fluid in the box. It was about 50
total miles with some mountain travel and I can say that the box goes
in and out of gear noticeably smoother and with less effort now than
before. I'll report back in 10 or 20 thousand miles.. ;-)

190,300
I have only had the car three months (tomorrow to the day).
Still shifts smooth and runs quietly.

And, BTW, that is 190,300 MILES.. should have specified, but you
probably figured that out anyway....

Many thanks Randy. I asked because we recommend a fluid change for the
AW30-40 (and AW30-43) autobox every 100,000 miles and it seems that a
similar period would not do any harm to the M46/47/90 boxes which should
ordinarily use Fully Synthetic ATF despite being manual boxes. Once again
thanks for the information.

All the best, Peter.
