Changing a Transmission 444-544

In about another month when it'll be scorching hot here in Phoenix, that offer of lunch at the pier will sound pretty tempting. :)

Too bad I don't know a thing about your transmission dilemna, except the type of 90 weight oil I recently put in mine (after thoroughly researching all options).

Here is what my research came up with for options:

Transmission oils without EP additives (non-hypoid):
Recommendation for: VOLVO (S) PV444, PV821/2, PV60, PV834, P544, 122S (1949-1960)
Engine CLASSIC MEDUIM
Gearbox TRANSOIL 90
Rear axle MILD EP GEAR OIL
Notes
v7 OVERDRIVE USE TRANSOIL 90

Oils that meet the GL4 criterion or at least compatible with the "yellow metals" in our gear boxes and diffs:
Redline MT-90 http://members.aol.com/SpiderParts/redlinealfa.html
Castrol ST90
MAXIMA MTL-E TRANSMISSION OIL, 32 OUNCE BOTTLE
Rock Oil ST90 $8.95 + $7 shipping at Scooters Originali (I purchased and used this and nothing disatrous so far in over 500? miles)

Misc notes from various places:
Transmission fluid has been well discussed on brickboard…the benefits of Redline and Amisol VS ATF or a synthetic 30W motor oil. Unfortunately the Search function here is very poor....there's pages of this stuff....1999, 2000, 2001.

Penrite make an oil called Transoil 90, it is a direct equivalent to good ol' Castrol ST90 and can be bought from Partmaster for a tad over
$10 per litre, note that SAE 90 gear oil is a similar viscosity to around SAE 40 motor oil, as their viscosities are rated/measured at different temperatures.

MTL - This 70W80 GL-4 Gear Oil (SAE 5W30/10W30 engine oil viscosity) is designed for use in manual transmissions and transaxles. Provides
excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.
Popular in many BMW transmissions and in most Honda and Acura transaxle applications. Confused with the whole viscosity issue. MTL...ATL...
70W80 is 5W30 viscosity? What? Regular ATF is a low viscosity so what is this 70W80 (sounds like Axle oil) yet they call 70/80 5/30.


Also, if I showed up, your wife might reconsider Not-getting-in-that-thing but in my experience it'd be out of pure jealousy considering I'm a 30-something female with (so I'm told) "way too many opinions about cars/car repair," so probably a bad idea all around. :-P

good luck
