Let Me Know if You Have Allison Transmission Fluid Questions

Hi Tom and welcome. Your expertise is of great value.

I have the allison 3000 which I changed over to tranSynd 2 yrs ago and about 12,000 miles ago. I believe a standard filter.
When should I expect to change the fluid again? This year I dont expect to put over 4000 miles on it.
My dipstick reads full but my shift pad says 1 qt low. Should I add a quart?
Where can you get TranSynd labels to attatch to your filler tube so anyone can tell your running TranSynd and not Dexron?

Well you asked for it.

Thank you so much.
