Best for B2650 owners doing this service themselves who want practical clarification beyond the manual.
Posted by the tsaipod channel, an owner sharing hands-on maintenance tips from personal experience on their own B2650.
The B2650 calls for four gallons of UDD2 transmission fluid, according to the manual and confirmed in the video.
There are three: one on the PTO housing, and two rear differential plugs, one on each side, nestled between other bolts.
The stick is yellow and hard to read, so the owner marks it with a Sharpie, which shows flat above and glossy below the fluid line.
The owner says the manual picture is misleading, making it hard to find the drain plug, which is actually nestled between two other bolts.
