I replaced my stall converter and nothing else in the trans so far. I have servo's and trans kit to be installed. I have been going down a flat road or down hit and my truck sounds and RPM prove that it has dropped a gear or something. I was down the road in over-drive A4 and drop into 3 and RPM increased a very little. This has started since the stall change. Do I need to get the servo's in and reprogram the computer to fix this or what? Thanks for the help.
