Came across this Shell Spirax ATF. It says approved as an Allison TES 295 replacement. I also posted the listed approvals. Enjoy.

I have an older car that specifies "Shell Spirax AX equivalent" ... Never seen one in store.
How old is your jug?
 
The jug is sitting on a shelf at my local Canadian Tire.
I see, thought it was in your garage. I should look for it in our stores. I've read good things about Shell Spirax gear oils ... iirc lasting up to 500K miles.
 
The "new"? Spirax S6 ATF is A668.

"Spirax S6 ATF A668 was developed to meet the extended
drain requirements of late model medium and heavy duty
Allison automatic transmissions. It is particularly suitable for
transmissions requiring a TES-668 type product and it is
backwards compatible with TES-295 approved fluids.

Approved:

·GM DEX II/ IIIG/ IIIH

Allison tes 295 is the gold standard of HD ATF, it will almost never break down in use. I have poured this oil in on a duramax (customer supplied), and have also used citgo quatrasyn

Citgo gave a much better shift feel though. But if this shell product is filled into a passenger car, its the last atf it will ever need.
 
For the amount of fluid Allison transmissions take better get a couple of buckets for a 'drain and fill'. A drain and fill nets about 60-70% of the transmission's capacity.

Don’t tempt me to try this in a Toyota T-IV application as well as a replacement for MaxLife and Red Line D6 for PSF.
