$8D with 3-spd auto
since ive only used 8D exclusively with the T5, i have almost no idea how the logics work with the auto trans. what would i need to change to use 8D with a 3spd auto?

There's really no control other than the converter lockup.
The IAC settings are different to make running smoother with the added loads from the converter.
If its not a lockup trans, just run the stock auto trans IAC settings and get the VSS to work and it should be fine.
