can someone tell me how to flush my entire system. Want to change from Dexron VI to TranSynd. Send a link or tell me step by step. 2006 silverado 3500 DRW 4X4. Thanks!!

There is a few ways you can do it. There is a good write up in the Do it yourself section. I think mackin or hoot wrote.

My local Allyson dealer, and have read others on this, does not recommend a power flush on the Ally. tranny. If you have shallow pan, drain and add 7.75 quarts, along with a new external filter filled with same fluid. Drive up to 25,000 miles, change again. Do this at least 3 more times, and concensus in that you will be at least 95% Transyd.

here is a reprint of the original (see post 14 on page 2). I used it without issues but I don't know what differences there are between my 02 and an 06....I used 6 ft of the clear vinal hose instead of the heater hose
