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: 2007 Dyna Models. The transmission should be drained and refilled with fresh lubricant at proper intervals.

NOTE

When checking the transmission lubricant level, the motorcycle should be leaning on the jiffy stand. Allow a short period of time to equalize lubricant level in the transmission compartments.

Check Lubricant Level

1.	Park motorcycle on the jiffy stand.
2.	See Figure 1. Remove the threaded filler plug/dipstick by turning the plug counterclockwise.
3.	See Figure 2. Wipe off filler plug/dipstick and place it back in the filler hole. Do not screw in. (Dipstick should rest on threads of the case.)
4.	Remove the plug/dipstick and check the level. The lubricant level should be in the hash marks between the ADD and FULL lines 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.	If the lubricant level is below the ADD mark, add lubricant. Do not overfill (bringing the level above the FULL mark) or leakage may occur. The transmission fluid capacity is approximately 32 ounces (0.95 liters). NOTE When filling the transmission, use Screamin' Eagle SYN3 Synthetic Motorcycle Lubricant (Part No. 99824-03, quart). If SYN3 is not available and addition of lubricant to the transmission 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 plug/dipstick and tighten to 2.8–8.5 N·m (25–75 in-lbs).

	NOTICE When draining or adding lubricant, do not allow dirt, debris or other contaminants to enter the engine. (00198a) 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)
3.	Inspect o-ring for tears or damage on the drain plug. Replace if required. Wipe any foreign material from plug.
4.	Install drain plug and tighten to 19–28.5 N·m (14–21 ft-lbs).
5.	Fill the transmission with 32 oz. (0.95 liters) of Screamin' Eagle SYN3 Synthetic Motorcycle Lubricant (Part No. 99824-03, quart). Do not overfill or leakage may occur.
6.	Install threaded filler/check plug and tighten to 2.8–8.5 N·m (25–75 in-lbs).
7.	Start engine and carefully check for oil leaks around drain plug.
