The head mechanical inspector came by our shop today to inspect our equipment. Inspector said that my truck was several quarts low on a/t fluid. My supervisor was in the room and asked what fluid the transmission takes. I replied, Allison/Castrol Transynd.
The mechanical inspector replied, its in the service book in the truck. Sure enough someone took it upon themself to handprint DEXRON III. I know for a fact since 2007 that Allison has been putting Allison/Castrol Transynd in their transmissions. Just goes to show noone where I work ever looks at actual factory manuals.
My question is will putting the Dexron in the tranny harm it in anyway? The damage if any has already been done because my coworker took the advice of one of the so called mechanics and and put Dexron/Mercon in the tranny. I know the older Allisons it was perfectly alright to put Dexron in. But, this is a 2009 Allison 3000 RTD 6-speed automatic. Any help would be appreciated.
