Synchromesh manual trans fluid

[odnorth]

l was reading the back of this Pennzoil jug l have for for my cars:
It provides excellent oxidation stability, low temp performance, excellent synchronizer performance and compatibility with yellow metals, such as bronze, brass and copper components found in manual transaxles and transmissions, there is more on the web site but looks like good stuff for the deuce trans, what do you guys think.

I do know that it is recommended for the manual in my Jeep TJ, and Dodge pickups. It lists the Chrysler spec on the bottle. For the deuce, I just throw in NAPA 90wt GL1 that I get by the pail. Can you get that Pennzoil stuff by the 5 gal bucket?

The correct lubricant for the spicer transmissions is 50wt engine oil.

 

[Sephirothq]

the synchromesh is expensive. it is meant to transmissions that are designed for it. I wouldn't spend the extra $$$$ for something that won't do any extra good. How long has the military ran the basic stuff??? it works for them

The correct lubricant for the spicer transmissions is 50wt engine oil.

So the LO is wrong?

 

[JasonS]

I would speculate that it was a compromise to make logistics simpler.

To me it is unknown that someone ever made a 50W engine oil. I'm over 25 years in the car and truck bussiness.
So it might be a misreading or worn out printing of 90W which makes absolutely sence without checking the manuales in detail.
Anyway, depending of the year of manufacture of yout trans, the brass of the syncronizing rings if of different quality.
To avoid problens, buiy a 90W GL3 or a 85W90 GL3. GL4 or GL5 qualities contain too much acid and will eat your syncronizer rings. The GL3 is also the limit for WWII transmissions beeing syncronized to avoid trans and transfer problems.

50wt engine oil is indeed the correct lubricant for a spicer transmission of this vintage/ design. See the attached scan from my 50s Reo maintenance manual. The local truck shop has it on the shelf.

50WT is NOT available in Europe! Thats why I do not know it. I checked up the suppliers.
According the reference lists it is the same viscosity as a 90W transmission oil. So my information is correct, even if with the "wrong" name.
