Been using Type "F" for years in my 340 car and B300 Van (also a 340 installed) and never had a problem. They have after all these years still have a firm shift, which tells be that the clutches are in good condition. My understanding is the quicker the shift, the less ware on the clutch disc, just as in a manual shift when your not riding the clutch. Did not know you could also use it in the 833 gear box and limited slip rear. I do question the limited slip usage, because I believe you may also have to use a additive or does the "F" already have "enough" added?
