Re: e40d troubles please help
Of course that helps. Did you think I asked the question just do see if you'd try it?
When shifting manually the trans applies the intermediate band in second gear. That band is ONLY used when the shifter is in the 2 position. When the shifter is in D during the 1-2 shift the intermediate one way clutch has to hold. In a manual 1-2 shift the intermediate band holds the torque instead of the intermediate one way clutch.
This tells me that the intermediate one way clutch is failing. The trans has to come out and get torn down to fix this.
