Wanted to do a transmission relearn on my 2009 LS460. Which is the latest techstream version that is compatible with this model? Also which is the latest firmware version for the mini vci cable that is compatible?

 

I think you need to do a couple more drain n fills and make sure the level is right and then just drive it for a few days, the learning process isn't something that gets to a certain point and then stops/locks.. it's always adapting to driver and various sensor inputs.

 

yeah thinking about doing exactly that. hope it resolves the issue completely but the first drain and fill made a huge difference
