fluid from dealership

[Night Owl]

Has anyone used the synthetic dex vi that you buy from the dealership? is that the transsynd? can i use dex vi in my tranny?

[blott22]

isnt the dexron 6 what the allisons call for??

[happyduramax]

it is not the same stuff, transynd is better then dex 6 , you can buy transynd from a alision dealer i don;t belive dex 6 is synthetic

[happyduramax]

allison uses transynd in there trans, gm uses dex 6 which it is fine , just transynd has longer change intervals and fully syn and made just for allision by castrol

For your 01, I would go with Torque Drive and you will be fine. Give Big Daddy Diesel, Mr. Manners, or Chevy Tough a PM and they can help you out!!!!
