mechanically, it is more just an issue with the driver

*Member shopdog stated: "To do any good, the

additive has to be worked in to the clutch packs. Since

the diff is a splash system, it is sometimes hard for the

slickum to find its way into the clutch packs before it

settles out (isn't miscible in the diff oil). That's why the

TSB says to drive the car in figure 8s immediately after

adding it. That makes the clutches slip, and lets some of

the slickum slip into the clutches too. I have a suspicion

that not all of the cars at the factory get driven that way

right after the diff fluid is added. Anyway, a few ounces

more additive in the differential won't hurt anything. I

wouldn't suggest putting 5 pints of additive in, but an

extra 4 ounces is cool."

*Member shopdog stated: "You need to realize that the

differential is a splash lubrication system. If the car sits

for several days without being driven, the lube drains out

of the clutches. Then when you first drive it again, the

clutches are working dry until enough lube works its way

back up there to relube the clutches. This causes uneven

wear of the clutches, and after doing this enough times,

you get chatter..."
