'01 Saab 9-5 automatic, Texaco ATF, 60k miles

This report is from my 2001 Saab 9-5 wagon, with the low pressure turbo 4 and an Aisin-Warner 4 speed auto. It uses Dexron III ATF. The 60k service calls for a single drain & fill. I did this using a Mityvac (removing 3L out of 7 or so) and topped off with Specialty Formulations Autoglide. I ran out of time to do things like clean the drain plug, so I'll hand the remaining 1.5 gal of Autoglide over to my mechanic to do several drain/fills and replace most of the factory ATF. The factory ATF made by Texaco was brownish and burnt smelling upon extraction. This tranny doesn't have a filter but has a magnetic drain plug, I believe. I am considering adding a Magnefine or similar filter down the road. The added Autoglide has improved the already excellent shifting. Blackstone Labs report: Miles on oil: 60,934 Oil type: Texaco Dextron III Comments: Since this was the original fill of ATF for the transmission in your Saab, that may be the main reason you see a lot of high wear metals and silicon. They could have all came from the break-in of the parts inside this unit when it was new. The 0.1% level of insolubles shows that the filter was at it's capacity of filtering. The viscosity was a bit low but not unusual for a factory fill ATF. Since ATF was changed, this unit may be good to go for a lot of miles in its future. Check back at 20,000 miles, which is average for the oil use for this type of unit.

I think I would stick to 30,000 mile drain/add in the future. It was overdue for a change in my mind and you did the right thing by changing it out completely. I would also do another UOA at that time to see how it is fairing.
