For comparison purposes here are my numbers on a Nissan Sentra tranny. These trannies are very hard on oil. They shear down fluid big time. Even Mobil 1 doesn't hold up. I now do a drain (4 quarts about every 10 to 15 K miles or so). I think its good preventative maintenance. -------------------------------------------------------------------------------- Miles..25,000....37,000.....47,858 Cu- 28......19.......33 Fe- 29......14.......15 Cr- 0.......0........0 Al- 11.......5........5 Pb- 3.......1...........2 Moly- 1.......0.......1 Phos- 623.....372......420 Zinc- 29.....18.......26 Mg- 1.......1.......1 Ca- 192.....248......326 Antifreeze 0......0.......0 Water 0.... .2..........0 Silicon 9......5.......6 Vis 5.32... 5.88......5.27 Analysis performed by Schaeffer

What is the visosity of your new oil Al. 5+ cSt seems normal for a transmission fluid.

If you would like to see real life shearing, check out the oil that comes out at 5000 miles from my 69 Nissan Patrol with a HINO diesel, the tranny is ancient 3 speed and makes Mobil-1 thin like water and dark. The tranny had to be fixed three times due to this.
