Yo Chip:

The only manual transmissions I've seen that require ATF are the newer
aluminum-cased units, like the M5OD five-speeds used in later F150/Broncos.  Our
aluminum-cased NP208 transfer cases also require ATF.

The original specs for the NP435 (back in the late '60s) called for SAE50 engine
oil.  Later (mid '70s) Ford maintenance docs I've seen call for 80W90 gear oil.
The change may have been simply for convenience.  Apparently both types are
adequate.

One of the main differences between engine oil and gear oil is the sulfur
compounds added to gear oil (they give it that distinctive smell) to prevent
galling on hypoid gear tooth surfaces (e.g., ring and pinion) that rub against
each other with a lot of force.  Since the transmission doesn't use hypoid
gears, the anti-galling compounds really aren't necessary.  Some people claim
that the sulfur compounds actually accelerate the wear on the bronze bushings in
transmissions.

A couple years back, a bunch of guys on the FTE 61-79 list talked about the
proper lubricant for the old-style NP435 and T-18 transmissions, and the
consensus was that SAE50 was a better choice.  Their thinking was it was the
original spec, and its somewhat lower viscosity eased shifting, especially in
cooler climates.

Jeff S. switched over to SAE50 in the NP435 in his '71 F100 4x4, and he said it
makes the shifting noticeably easier and the gears seem to mesh more smoothly.

Yes, I discovered that.  I also discovered that if you disconnect the front
drive shaft and leave it to just hang, that it opens up the seal and the ATF
leaks rapidly out onto the tire that I put right under the transfer case and
then onto the floor.  One thing interesting to note too, is that it just
opened the seal and didn't crack it.  After I put the thing back together
and attached the driveshaft, the leak went away.  I did refill it too. :-)

Interesting.  My ex-brother in-law had an old car, 40's vintage, that had
both the transmission and engine lubed by the same pool of oil.  I believe
it took 11 quarts of oil during a change.  I suspect that the 50W oil is a
bit cheaper too.

That's interesting too.  Regular gears do slide on each other, but not to
the extent that hypoid gears do.  It's probably on the level that engine
parts such as the oil pump and valve lifters do.

I can tell you that _filling_ the transmission with 50W would be about 100x
easier than with 80-90W.  I filled the diff. Tuesday when it was nearly
freezing in the garage.  It was like squeezing two quarts of honey through a
small tube.  A good forearm exercize.

Do you know if multi-viscosity oil would be adequate?

Thanks for the advice and information.

Anthony,

Most auto parts stores sell inexpensive devices to retrieve your computer
codes if your not able to pull them off via the methods on those two
websites  mentioned earlier.  They cost about 25-35 dollars and are
reliable.  I've used one on our three fords for years.  They come with a
book listing the codes and descriptions.  Good Luck.     Walt

Ken,

Try as I might, I could not find their ad on the home page, nor any
sub-pages.  I went directly to their page, but thought that you might
have a "referral counter" in place, so wanted to go there through a link.

Where?

Marv,

Sorry about that.  Given the number of ads displayed on the

Hi Craig,

Have you noticed how often that *sweet spot* is always 10 or 15 clicks over
the speed limit ???
