I noticed that on the new 6L80's you can only select to have TM on/off. On my 4L60(Silverado) you could remove any percentage you want. Is it something that will be getting updated soon.
My brother has a new 2010 Camaro and with the TM on off it shifts too hard at the track and spins into 2nd and 3rd. What can I do to soften it up a bit?
