Only doesn't upshift manually properly from the wheel paddles, or doesn't upshift properly in normal drive or sport mode as well? If it's just manually from the paddles, that does sound like faulty electrics there.
~Only in manual mode. Works fine in automatic mode
The lack of downshift to second is manual or auto mode? What on earth do you mean by the cooler being blocked off? Removed from the cooling loop? If you block that loop, that's not a good thing.
~Downshift issue only in manual mode; works fine in auto mode
~The air is blocked from the cooler fins with a piece of cardboard only. It is in series with the OEM radiator cooler.
Not throwing a code is good. Seems like the TCU keeps pretty good tabs on the trans, so if it was a VB issue or the actual vs. selected gear was different, it would let you know.
Thanks for the reply!
I think the contact points on the upshift paddle are dirty and will try to clean. If switch is faulty, doubt SOA will doing anything about it with 63K miles on the odo. Will just use auto mode or shift with the console lever and get it fixed after I get the F1 VB mod when available.
