I am working to fix a transmission leak and hard 2-1 shifting on my '08 750LI. I see via my VIN that my transmission is 6HP6Z (aka 6HP28). When I watch videos of people replacing the solenoids, they are clearly red (x2), blue (x2), and yellow (x3). However I ordered from amazon and ended up with solenoids that are colored differently (dark yellow, brown, and black/dark green). This is confirmed from two suppliers on amazon both of which had pictures of yellow, red, blue solenoids.
Looking on ebay, I see the same issue of people selling different colored solenoids.
Can anyone confirm if the discolored solenoids are ok replacements, and if yes, what is the correct color scheme?
