R320 Transmission Software Flashed
Our R320 has been shifting riugh from 1st to 2nd. like it "clunks" when it shift. took it in and the dealer upgraded (flashed) new software into the transmission. not only does it seemed to have cured the "clunking" but overall it seems smoother. i don't know enough about the invoice codes to decipher any type of level or rev they installed.
