You may already know this, but when I am at dealerships, I see most of the "techs" spending far more time on changing the primary fluid than is necessary.
Most of the time you see them removing the passenger floorboard mount to get to the one derby cover torx that is blocked by the passenger floorboard.
This does not take a terribly long time....UNLESS you have Adjustable Passenger Pegs mounted to the floorboard....then it take a Much longer period of time to remove the passenger floorboard mount to get to that blocked torx on the Derby.
Tip on how to make it faster-
1. Remove the floorboard rubber pad (it just pulls off)
2. Push out the retaining pins (use a screwdriver, allen wrench, whatever's handy)
3. Remove Floorboard
The whole process takes 20 seconds.
Now you have access to the blocked torx fastener. (keep track of the spring and ball bearing that are in the floorboard mount)
Now you can refill your primary.
Once done, replace your Derby cover, put the floorboard back on the mount, pushing the two pins back in place, then put the rubber pad back on the floorboard...it just pushes on. Sometimes a little silicone spray will help the rubber tits to go back thru the retaining holes more easily.
