Chevy 6.5 Diesel Man
1998 K3500 - 4L80E
Fluid was light brown. Shifting was ok but lost OD sometimes and a cpl times had limp mode. Reverse had a shudder and slip but works.
Changes fluid to the good stuff and filter, etc. Cleaned the sump - fine dust like graphite sludge, like a thin coating over the inside of the pan.
Truck shifts good now. Reverse is still a problem.
Thank you.
PS Because of the service the fluid looks better but the torque converter (6 qts. of so) has contaminated the good stuff. No power purge for me as it might screw up the works completely.
