I have done allot of research on what fluid to use after the break-in using the dexron III. I have found it not only confusing but misleading in many case's and not founded on facts. So I contacted Tremec and specifically asked about the Tremec T56 Magnum XL.

Here's the answer I received from tech support today for anyone who needs to know.

Good morning Nick,

Thank you for your interest in the Tremec Product Line. We do recommend Mobile 1 Synthetic AFT and Pennzoil Synchromesh fluid for your application. Some people have a hard time finding one or the other but they are both good fluids to use in your application.

Regards,

Dont use the gm synchromesh they recommend on their web site. After i break mine in with mobile 1 i'm switching over to this:

Im using dexron III for the first 400 mile break then switching over to moble 1

Mobile1 synthetic ATF works well. I've also seen a lot of guys use Redline ATF with success. I don't think you could go wrong with either, plus it's nice to use exactly what the manufacturer recommends too.

BTW- I'm jealous of your T56 Magnum XL upgrade. Enjoy it!

lol, Thanks. Expensive road but, I was not going to sink money into the 3650. May as well toss it out the window..

That it is expensive, but you can't buy a better trans! Now you'll love the smoother shifts and the fact you won't have to worry when rowing gears. Which is important when sporting a positive displacement blower, like the E-Force.

Good luck with it!
