Your '08 does in fact have the "easy pull" clutch. Not only does it have the 9 pack, it also has the longer throw on the Ball and ramp. While I was working at the dealer I replaced a lot of the 9 packs with the older style 12, and kept the easy pull style ball and ramp. This was done for the guys that wanted to spend the $200 on a new clutch pack. For the ones who didn't, I built some performance clutch springs to add to the 9 pack (can also be used in the 12) This worked great, and they never had any more slipping problems.
I would recommend removing the primary cover, and inspecting your clutch along with the throwout bearing. If you need help getting parts, let me know. I can get them, and ship them to you.
-First, check your dome height of the clutch spring using a straight edge and feeler gauges. The spec. is .010" - .050"...It's less apt to slip when height is closer to .050".
-Second, remove 4 bolts (5/15-18) that hold the clutch pressure plate on, in a Chris cross pattern. Inspect the pressure plate for wear. If it has groves in it, it should be replaced. ($50 retail)
-Third, remove all the plates starting with the front fiber, keeping them in order in which they came out.
-Forth, once all plates are removed, measure the fiber thickness using vernier calipers or micrometer. The fiber disks should be no less than .845"
If they are less, they should be replaced. You will also want to inspect for obvious wear/grooves and bluing of the steels. The steels can also warp under extreme heat, so check them on a surface plate, or piece of glass. Should be within .002" flat.
-Fifth, check for play in transmission main shaft. Any play at all, up down/side to side, or in and out, bearings in transmission are worn and should be replaced.
Let us know how you make out. And, as far as the dome height on the spring, that can be adjusted if it's not at the .050". I'll go over that with you when the time comes.
