70-80-90 weight gear oil should work in either one, lean toward 90 on the rear diff.

What about the use of synthetic in these trannys.  Do you have recommendation s?

Would work fine, I'd lean more to 90 or even plus a bit on diff.

I'd use that in the rear, might make shifting stiff in the cold in MTX.

With Redline MTL, the stock 4 speed will shift like it got hot butter for lube. If you want to try different lubes, do like I did and put a drain plug on the bottom of the tranie at its lowest point. You can even do it with the tranie in the car if you start out with a small drill, and a big drain pan. I taped mine to 1/2-20 as a lot of drain plugs are that size.

I'm currently rebuilding a 1980 Pinto 4 speed FOG tranny and am looking for the right fluid.  Would you recommend one of these, or should I go with traditional fluid?

I use Sta-Lube GL-4 gear oil for gearboxes that take gear oil and any ol' GL-5 for rear ends.

GL-5 should not be used where yellow metals are exposed to the oil. That means the brass blocker rings in a transmission.. .

This is quite interesting. I've had people recommend the following GL-5 since it's not synthetic, but your point changes that as my trans has brass rings and brass thrust washers.  NS fluid was recommended due to the friction modifier in synthetics.
http://www.redlineoil.com/product.aspx?pid=47&pcid=7

The Pinto shop manual recommended ESW-M2C83-C (see below).  This manual was written in 1979, so is there a comparable product made today?

PRODUCT DATA SHEET
GEAR OIL 75W/90

properties ensures good shift feel and fast gear change. This gear oil is ideal for today’s 4 and 5 speed manual gearboxes which need low viscosity oil for smooth gearshifts. It is recommended for use when SAE 75W or 80W oils are specified.
GEAR OIL 75W/90 has excellent cold temperature characteristic s which ensures maximum protection to gearboxes and differentials.
BENEFITS
GEAR OIL 75W/90
• Excellent cold gear shift and superior protection when hot
• Low gear wear
• Anti-corrosion agents for longer gear life
• Anti-Oxidants for longer oil life
• Extreme pressure additives for low gear wear

A lot of the old specs like GL-1, 2, and 3 and Dextron-I/II/III are obsolete, partly because the vehicle they were for are too.

If you can get some guarantee from the manufacturer that their GL-5 is suitable for use with yellow metals, I would run that. GL-4 is the otherwise safe fallback that is still actually available. There are some motorcycle gear oils that meet GL-3 and 4 specs. Silkolene is one.

Makes sense.  You stated that you are using Sta-Lube GL-4. Is that something you recommend for the older Pinto trannys?
Where is it available?

Old-timey auto parts stores used to carry it. I got it years ago from a Parts Plus that later became an Advance Auto and is currently a Napa and they still stock it...to the tune of $38/gal.  :o

How much fluid do we need in the 4 speed tranny?
(I'm seeing quarts of other trans fluid listed at $16 at various places, so $30.19/gal isn't bad comparatively).

While on the subject, I don't recall anything in an open Ford 8" (circa late 70's) that was brass but..., when I swapped out my 3.00's for 3.40's  I used the GL-5 I had on hand.  So..., just wondering?

I found this interesting and thought I would post it for everyone:

Warning About Gear Oil

WARNING:
 All modern gear oil available today in local retail outlets is GL-5 grade. GL-5 grade gear oil contains sulphur compounds that attack brass and bronze. BMW transmissions and final drives made before 1992 contain bushings and thrust washers made of these metals. Any brand of gear oil that is GL-5 rated will attack bushings and thrust washers.

 Look for:
 acc070A--$8.95--80W 90 GL-4 gear CRC brand

 CRC® Sta-Lube® Multi-Purpose HYPOID SAE 85W90 Gear Oil API/GL-4:

 CRC® Sta-Lube® Multi-Purpose HYPOID SAE 85W90 Gear Oil API/GL-4 is specially formulated to meet the unique requirements of API GL-4 service in manual transmissions and transaxles of passenger cars, light trucks and SUV’s. CRC® Sta-Lube® Multi-Purpose HYPOID SAE 85W90 Gear Oil API/GL-4 is blended from select base stocks and additives that yield a lubricant of exacting quality. This product is compounded utilizing specialized extreme pressure chemistry that provides protection of gears and bearings without being corrosive to bronze components. It contains foam suppressants to prevent wear, which can be caused by lubricant foaming and aeration. Effective rust and corrosion inhibitors protect metal surfaces from the effects of water contamination from condensation and the operating environment. CRC® Sta-Lube® Multi-Purpose HYPOID SAE 85W90 Gear Oil API/GL-4 resists the formation of varnish deposits on synchronizer components, thus assuring long, trouble-free operation.

 CRC® Sta-Lube® Multi-Purpose HYPOID SAE 85W90 Gear Oil API/GL-4 gives the full protection of an SAE 90 under hard driving conditions while providing the flow characteristic s of SAE 80W that are necessary during cold weather start-ups. This offers maximum lubrication and gear protection over a wide temperature range.

 CRC® Sta-Lube® Multi-Purpose HYPOID SAE 85W90 Gear Oil API/GL-4 is designed for manual transmissions and transaxles of both American and import vehicles. It is formulated to be compatible with “yellow metals”, such as bronze, found in synchronizers and other transmission components.

 BENEFITS:

• Meets the performance requirements of API GL-4 Service
• Will not cause glazing of synchronizer components
• Excellent thermal stability
• Outstanding extreme pressure and antiwear protection
• Prevents rust and corrosion
• Inhibits foaming and aeration

I'll add that GL-4 was specified for some gearboxes at least into the mid 1990s, but it started disappearing from shelves about 15 years ago. A lot of manufacturers still make it, especially for the Euro market, but most chain stores don't stock it here. >:(

Stocking even just one brand/type of GL-4 would be nice for those of us who need it. Pennzoil Synchromesh inventory moves at least as slowly as GL-4 would and Synchromesh is always stocked. I can still find it in containers with the label design that changed last year.

Good point. 
There are some challenges when your hobby is restoring older cars.  I looked around for the right trans fluid but only found stuff for today's cars.

I did find this and will most likely order it.  The quantity is way more than I need, but at least I'll have it around for future use... (when this stuff becomes really impossible to find).

For something as lightly-loaded as the driveline in a 4cyl Pinto, whatever is cheapest will be fine.

Anyone out there know what GL-6 is or was. Just saw some lube at Walmart that said it replaced GL-6. Price was the same as GL-5. The bottle did not have a GL # on it.
