ATF in a Saginaw 3-speed?

[bmodracer]

Talked to a guy who said he has been running ATF In his Saginaw 3-speeds for years with no problems......is that possible?

[lilsumo]

Yes the only reason for gear oil is to keep them quiet. Auto trans fluid is fine.

Same here ATF is all we have ran for years.

[bmodracer]

What type is normally used?

[SRT17]

How much do you put in?

[ric78]

I just used Dexron III/Mercon. Fill just as you normally would, until it starts to come out the drain plug on the side.

Atf here as well. Dexron 6 till it comes out of the fill plug.

[lilsumo]

I used whatever was on the shelf at the local family dollar and filled it until it came back out as normal

10 w hydraulic oil works good also
