I have a 2000 Road King Police. What kind of transmission oil do I use? Generic name?

SOURCE: where is the oil dipstick on an 03 road king

The oil dipstick is located on the right side of bike almost directly under the football cover for the air cleaner. It's a round knob that pulls directly out (Kind of wiggle as you pull on it). Just check like a regular car dipstick pull, wipe and reinsert and then look at dipstick.

You could get away with it for awhile, but I would only use oil formulated for the primary chain case, and for that part of the machine, I stick with Harley brand, dont forget , u got clutch plates in there u dont want slipping. For the tranny you wanna use a good grade gear oil (75W-90, 75W-110,75W-140, SAE 190 & SAE 250) .... it'll better handle the torque requirements. I use Redline Gear Oil and shifting has improved noticeably

The drain plug is on the left side of the oil reservoir pointing towards the front of the bike. The motor should be warm when you dump the oil and the o-ring should be replaced as an extra precaution (don't want to waste that new oil if you have a drip). When replacing the oil filter use a piece of tin foil to divert the oil to your waste pan.

the oil tank is on the bottom of the transmission in your RK. There are two drain plugs. The plug towards the front left of the pan is the oil drain plug. The other one is for the transmission.

Drain the oil, replace the filter, refill with three quarts of oil and you're ready to go. The dipstick has two marks on it. The upper mark is "FULL HOT", and the lower mark is "FULL COLD". Do not overfill.

Don't forget to service the transmission and the primary at their recommended intervals.

Good Luck
