Allison 6sp: Normal/safe trans temp

[Fat_Robi]

I just went from Provo to Las Vegas and back this weekend towing my jeep (about 5000 lbs ish) and I was keeping a close eye on trans temps. most of the time the trans temp was about 100-110 above ambient air temperature. When I tried to keep it under 200 degrees because I don't know how high is safe. So what is a safe trans temp? These temperature readings were from the DIC and thermometer on the mirror. Just wanting to get a reference on things.

Anything below 220F is safe providing you run good fluid. TranSynd would be best.

Where can you purchase that fluid? Local auto part store?

Allison dealer...you can find your local dealer from their website.

On edit: I forgot it is a Castrol product so anyone that sells Castrol may be able to get it for you. I tried the local farm store but all they could order from Castrol was 5 gal...and iirc the Alli dealer was cheaper per gallon.

TranSynd although a Castrol product cannot be sold by Castrol ditributors. Must be bought at an Allison dealer.
