I know this has been asked before but I was wondering what kind of transmission fluid that people are using in the allison transmission.Is there any certain brand that seems to work better or is prefered.
thanks jOe

Nope, just stay with a name brand. I've only topped mine of when changing the filter, think I used Penzoil brand, never a complete change yet. By the way, you can get the filter from most Allison dealers for around $8 rather than buying from a GM dealer.

Mobil 1 Synthetic ATF. Valvoline also has a synthetic ATF but it is harder to find. Get at least 7 quarts to drop the pan and change the filter. About 12 to flush the "from cooler" line. Good idea to do this regularly.

Some use TranSyn, but I have not figured out where to get this...

I use Mobil 1 ATF,when I change the fluid. I think The Transynd is available thru Allison or the dealer. I don't know why you'd buy it from the dealer though. Any Dexron III ATF is fine for the Allison.

If you go to Transynd, in general use you go to 100,000 mile oil change!

Take a good look at Transynd if you tow or haul frequently. Great stuff!

How much are you paying to have someone do the fluid/filter (internal)change? I've changed the spin-on (and I agree, why pay the stupid dealer 3x the price? Get it from Alison shop). If I want to change the internal filter, I need 7 quarts? What torque when replacing the pan? Need a new gasket?

If I try to change the fluid myself....how do I do it? Pull the 'from' line at the transmission? Need to do an exhange or just pump it out and then replace?

The only time the internal Allison filter is changed is when the trans is rebuilt. Later! Frank

Use TranSynd in your Allison and you can't go wrong. My trans worked noticably better on TranSynd and ran a min. of 20 deg. cooler.
