I had same oil issue, on a steep incline. the truck is 2001 it happened probably 15 years ago,,, just the design of the engine... never had an issue since

check battery connections, and voltage

I was told 9 months after in service date.

no problems after replacing scr about 7000 miles

yes, replaced on 2018 mru 16,000 miles … don't recall the code

I have a 2018 Mack MRU, 14000 miles . its been to dealer 10-12 times... e-service is involved, bottom line Mack and their people don't care, (not the dealer) Mack Corporate is a mess. There is no customer service, todays Mack, is not of yesterday,,,,,, very sad

could be suspension rattle, insulator spacer

take torque converter bolts out.... pull trans..........flex stays with flywheel

try Adelman Truck parts, canton Ohio
