Let Me Know if You Have Allison Transmission Fluid Questions

The big question I have is how can I save money on TES 295 approved fluid?

Most of the TES 295 approved fluids on the Allison list I can't find for sale. If I can find them for sale they cost as much or more than Transynd. I have numerous places I can find Transynd locally.

I probably should change my Transynd as it has been almost 5 years and 25,000 miles. The fluid should probably have been chnaged even earlier as I had non TES 295 fluid in there before so I have a mix right now.
