So I downloaded the FREE SSM and purchased my cable on Amazon for about $7.
Note: Before attempting this I changed transmission fluid, Transmission filter, and took to dealer after reading a TSB about the 2nd to 3rd shift saying a firmware update may help. Only thing I got was a $125 charge and they claimed "yup all better" yet still the same.
Pretty much did what post 40 says.
- Connect to OBD than to laptop
- Open FreeSSM
- Click on transmission
- Click clear memory #2
- Follow instructions. It will tell you something like turn ignition off, than to turn ignition back on and to wait patiently.
- Once complete I drove my Legacy for a few miles during which I let the car shift on its own. I did not use the paddle shifters very much. I did however put in sport mode and sport sharp. Also I cruised around a bit and did some semi hard acceleration as well. A few hard decelerations.
- Transmission is now smooth as new. Only problem with this fix is that after driving with slippage for a while, its like I would always expect the slippage and really never got use to it. Like "here it comes... yup there it is".
So after fix for a short while it's as if your body is waiting for that slip and now nothing. Weird feeling but goes away after about a week. Next day I put into manual mode and used my paddle shifters a bit and slippage is no more.
