Recently my ATS Stage IV Allison has started whining profusely. The thing sounds just like a hydrostatic drive tractor. Anyone heard of this before??? Also seems like torque converter is staying locked as it bogs down and wants to shutter when holding the brake in gear(no throttle).
Im running a modified big Quad EFI Live tune and a Hot Edge Stack.
I pulled the thing all summer with great sucess and no problems but then this winter when i havent even been runnin her hard, this happened????
While it is still driving I am wondering if i should stop driving it immediately
