Are you say that it slips when the OD is engaged in 1st and 2nd? The overdrive should not work in 1st and 2nd (and reverse), there should be an inhibitor switch to stop this.
You should use a GL4 spec oil in the gearbox. GL5 oils have additives in them that can eat away at some of the components (copper washers I think). I'm not sure what spec Mobil synthetic is, but I use castrol EP90 GL4 oil. cheers John --- M Klish <[EMAIL PROTECTED]> wrote: > Dear Spitsters - > > I recently installed a J-type O/D in my 74-1500.
