(I'll pause for a moment for all of the scolding ... I absolutely deserve it). I want to flush the fluid before I change the connector plate / plug / filter. Gonna vacuum the fluid out through the fill tube, replace the fluid, run the engine, cycle through the gears, and repeat this process three to four times. When the fluid is red again (guessing that it is black now), I will do the connector plate / plug and filter replacement. I'm guessing that I will go through 12 to 15 quarts of ATF. I don't want to cheap out this job, but I also don't want to pay the dealership $23 / liter for ATF 134. I saw one video where the guy used Valvoline™ MaxLife™ Multi-Vehicle ATF. It is Full Synthetic. On the back, it said approved for Mercedes NAG-1. I saw somewhere that this is the Sprinter designation for the 722.6 transmission. So, here is my simple question after all that explaining; Can I use Valvoline™ MaxLife™ Multi-Vehicle ATF, or Shell ATF 134, or another type of fluid for the flush and refill? Thanks in advance.
