Hi,
I'm new to The Diesel Page Forums. Have been lurking in the background for a couple of weeks. I recently purchased my 02 Chevy HD2500 S/box Ex/Cab 4x4 Duramax with Allison Tranny.
The truck has 65000km (43000miles) and I don't know if the transmission has been serviced yet.
I am considering changing the tranny oil to Amsoil ATF. Amsoils website states that it is compatible with Dexron III.
Is any one running it in their Allisons now?
How does it perform?
Any input would be appreciated.
Thanks for your help.
Kim
