General

The transmission lubricant level should be checked monthly.

Your motorcycle comes equipped with Screamin' Eagle SYN3 Synthetic Motorcycle Lubricant. For transmission lubrication, it is not recommended to mix SYN3 with other lubricant products.

Refer to Maintenance Scheduling → Regular Service Intervals → Regular Service Intervals: 2005 FLHTCSE2. The transmission should be drained and refilled with fresh lubricant at specified intervals.

NOTE

When checking the transmission lubricant level, motorcycle should be standing STRAIGHT UP, not leaning on the jiffy stand. Keep motorcycle upright for a short period of time to equalize lubricant level in the transmission compartments.

Check Lubricant Level

1.	Ride motorcycle until engine is warmed up to normal operating temperature.
2.	When the engine reaches normal operating temperature, turn the engine off and position motorcycle STRAIGHT UP and LEVEL.
3.	See Figure 1. Remove the threaded filler plug/dipstick.
4.	Wipe off filler plug/dipstick. Place in filler hole and remove. (Dipstick should rest on lip of filler.) Do not screw in. Lubricant level should be at the F(ULL) mark on the plug/dipstick when removed. NOTE Lubricant level should be between the two marks on the dipstick.
	WARNING Be sure that no lubricants or fluids get on tires, wheels or brakes when changing fluid. Traction can be adversely affected, which could result in loss of control of the motorcycle and death or serious injury. (00047d) NOTICE When draining or adding lubricant, do not allow dirt, debris or other contaminants to enter the engine. (00198a)
5.	Add lubricant, if necessary. Do not overfill or leakage may occur. The transmission fluid capacity is approximately 24 ounces (0.71 liters). a. When filling the transmission, use Screamin' Eagle SYN3 Synthetic Motorcycle Lubricant. b. If SYN3 is not available and addition of lubricant is required, SYN3 must be completely drained before using other lubricant products. A residual amount of fluid will remain. It is not required to flush out the residual fluid.
6.	Inspect o-ring for tears or damage. Replace if required. Wipe any foreign material from plug.
7.	Install threaded filler/check plug and tighten clockwise to 2.8–8.5 N·m (25–75 in-lbs).
