Dextron III and IIIH - some Canadian content!

I moved this from another thread and added today's shopping experience.

There aren't that many brands for sale in my area that still comply with that.

I did a quick lookup of Swepco and I don't see any reference to it being on spec.

It sounds like good stuff but the discussions I found were around it being used in trucks and heavy equipment.

Zach - I was just checking on-line and it seems CT only has their own brand in Dexron III. Might be OK, but did you find any other sources?

Checked further around our town.
- Walmart had only 1L bottles of their no-name brand, 3.78L jugs of Castrol Import Multi-vehicle for C$27.99 (1L bottles C$8.47) and one 5L jug of Valvoline Dex/Merc for $31.97. No 1L bottles
- Went to PartsSource. They and Canadian Tire had the Castrol at an even higher price. But they both had Mobil Super ATF D/M which says it is rated for Dextron IIIH. $27.99 for 5L and $6.49/L. They of course also had a cheaper no-name brand.

Wondered whether Dextron IIIH is same as what we call Dextron III. This link explains what it is:

General Motors Oil Specifications - oilspecifications.org

Doesn't of course tell us if it is good for our old Benzes.

This link does provide some insight and is a useful summary of ATFs.

I ordered Filter kit today and will most likely use the Mobil ATF. (This for my 85 300D)
