I'm buying an Alfa with a C7 and an Allison 3000. The tranny had an oil change 4 years and 25k miles ago. Do you change the trans fluid due to time?

Here is the right way to change the trans oil, and use TranSynd TES 295 Fluid

Ditto on this

Also go to the Allison Transmission web site there you can find what the oil and filter change schedules are,

I do mine every three years using Transynd Transmission Fluid and as of two days ago the cost of materials, 5 gallons of fluid and filters, was $311.36, the filters were about $72.00 the rest was the fluid. This was from Detroit Diesel in Fresno Calif.
