Changing auto transmission oil on 72?

The double "service life" claim is B.S......Most ATF's that claim the be full synthetics use ONLY group III base oils.....Mobil 1 ATF is a good example.

How true. Allison said the new TES-295 would be ok for 100,000 ..... Then next thing ya know a service bulletin (Allison 1099B ) came out that now says 50,000.

Thats under "severe" use, "Regular" use is still 100,000.
