Gonna bump this question. As I'll be refilling my trans this weekend and want to know if Amsoil will handle extreme colds. Amsoil site says nothing.
I wouldn't use it in the extreme cold. It's too thick until it warms up. stick with the synth ATF
Good to know, thanks!
Man, everyone was telling to run synth ATF. Then i talked to a tranny tech. He said the ATF is too thin and too slippery to let the syncros engage fully.
Mine held just under 6 quarts
On the Amsoil page for Manual Syncromesh Trans fluid here if you scroll down to the stats the cold pour point is -49 degrees or -45 c. I think that should handle any cold weather you can throw at it here in the states.
i know this thread is old but have been wondering how well the amsoil manual trans/gear lube is working out?
I know this thread is extremely old now, but have you had any problems with your transmission and/or transfer case after switching to Amsoil MTGL?
How many miles did the truck have on it prior to changing fluids? And did you use GL-5 or GL-4? Synchromesh transmissions use GL-4. Because GL-5 contains sulfur, which eats away at the brass synchromesh. And the 5 speed in those older Ford trucks is a Japanese design Mazda transmission. So Lord knows what kind of stuff is goin on inside there.
