If you have the EFILive Scan&Tune cable/hardware, then yes you can command the shift solenoids...

download/install the latest V7 software from the EFILive downloads website...

then start the scantool, connect (green button on upper left), goto DVT tab...

let me know if you can't figure it out from there.

Many of the trans tables use VSS and TP... so you want both of those signals to be good.

The latest one V7.5.6.157 has various bug fixes...

but if V7.0 works on your car then you should be ok.
