you can't reformulate better than perfection! Allison already accomplished "non existent wear" after 14,000 hours and 7 years of road testing the original 295 fluid 18 years ago...

Well for info they have improved the 668 fluid. We know It carry’s heat away better than before. Until I get solid info from the the engineers I won’t post on additives or claims. If Allison approves any fluid then that means it met the original build spec and has the approval sticker.

How and no we don’t.

What are you guys seeing for temps when double entered?

So for the guys running 295 that switched from type f are you just draining the trans and switching what about what’s in the convertor

yes, I made the swap from Type F back in 2005 iirc. Figured the fluid was all Transynd after the second trans service.

Thanks Ed that’s what I was thinking just wanted someone to confirm

The new spec allows Allison to back long drain intervals, even when operating under heavy loads. For Allison there are two drain intervals – a standard drain interval linked to Allison-approved TES 389 fluids, and extended drain interval linked to Allison-approved TES 295 fluids. DuraDrive HD Synthetic 668 will have the same extended drain recommendation as TES 295 fluids.

The new oil is specified for on-highway vehicles, including vocational applications, and is fully backwards compatible for every Allison transmission that requires an Allison-approved TES 295 fluid.

Benefits include:

Smoother performance: Anti-shudder and torque control mean it’s easier to drive, with smoother acceleration and faster point-to-point acceleration, even under demanding conditions.
Maximum durability: Excellent oxidation control helps shield components from damage caused by sludge, varnish, and corrosion, for improved fluid life and transmission component life.
Enhanced protection: Improved wear protection means longer transmission life.
Petro-Canada officials touted the extensive testing the oil went through. It involved thousands of hours of severe testing in an Allison transmission done at conditions beyond standard operating parameters. DuraDrive HD Synthetic 668 has been fully tested in frigid North American winter conditions and in the heat of the desert to ensure its ability to handle temperature extremes.

For instance, the ABOT (aluminum beaker oxidation test) showed the oil offers 14 times better oxidation control than the requirements, as well as excellent oil thickening control. In anti-shudder durability testing, it performed twice as well as the requirements. Optimal wear protection improvement was confirmed with the FZG ASTM D5182 test.

The 99.9% pure synthetic base oil provides exceptional volatility control, according to the company.

"There are two important factors when formulating a fluid – volatility control and oxidation control," Sonia Hevia, product specialist – transmissions at Petro-Canada Lubricants, told HDT. "The right combination of base oil and additive technology brings you to the level of oxidation control that we see with DuraDrive HD Synthetic 668."

Petro-Canada officials said the new oil gives customers an immediate opportunity to maximize their uptime and reduce maintenance downtime and costs, upgrade their performance, and extend their asset life.

Allison Transmission is in the process of providing additional approvals for multiple oil marketers.

Meanwhile I spoke to a Castrol engineer who confirmed what I have stated here, 668 is the same as 295 not new and improved.

Make no mistake , both good fluids but I think your engineer was a sales person.

I looked up who I spoke to.

I just took delivery of 6 gallons of Transynd 668.

Hopefully it performs at least as well as the store-brand Type F I’ve been running for several years. I’m confident it will.

Pretty tough to be exactly the same with different viscosity.

Hey Tony,

I was just looking into this as I used 295 in the past. Can you share where you placed your order? And was the price competitive?

Just stop at your local truck stop an pick up some SHELL SPIRAX 295..same shyt with different label an cheaper

I paid $140 for each box of 3 gallons on Amazon. It just arrived today, and it is now $150 from the same seller.

Thats what I run. Shell, 295 allison specification. Works just fine.

Ed how is it the same with every data point different? I'd be fine if it was the same but it is clearly not the same stuff based on the data.

Probably will make zero difference in a race car...

Is that your logic on claiming it's the same stuff. Because the data says it's reformulated.

And the castrol engineer says it’s not. I’ll go with him.
