Question what is the dealer checking? is he actually pulling the cover and measureing the clutch discs? Or just checking that the fluid is correct?
Fords LS unit is a clutch type, they normally need to be replaced aroudn 25-30K miles. Beat on it and they need to be done sooner. They have used the same design since I can't remember when. It is not a lockup type, and depending on loading one wheel will slip while the other tries to get power.
Tru-trac is a better unit to upgrade to as it uses gears not clutches. The 450/550 D110 are Gear type LS units. I have 78K on my rig and the LS unit works just fine, but then again I do not drag race the machine just work it for what she is. Occasionally I can spin one wheel but the other will generally apply some power to the ground and get me moving.
