Even the retailer selling these is not making any claims of power gains. It has long been understood that air filters and intakes on this platform don't do anything for power. It has also been established in objective testing that aftermarket gauze and oil type filters just don't filter nearly...
Normal behavior of this transmission, as others have said. Some are better than others. My ATS-V was horrifically bad. Fluid change and a clutch bleed improved things quite a bit, but was still notchy and required a lot of effort. My 4bw 1st to 2nd shift is wonderful with just a hint of notchiness.
This kind of oil consumption is completely unacceptable and you should elevate this to GM if you are being blown off by the dealer.
Amsoil isnt going to fix it and there is no reason to spend that kind of money on oil when no less quality oils are available at half or third the price of amsoil.
Downpipes without a crossover on an LF4 sounds pretty bad. That was understood a few years into the ats-v life cycle.
And the deal about downpipes without an CEL.....If they are not reducing cat efficiency (since there is no CEL) to flow better, what makes them less restrictive than OEM?
Its a direct linkage, not a cable. The shifter is mounted right on the transmission so yes it will vibrate. I also noticed this characteristic when going from a wrx to an atsv. That's why it is so direct. Nothing to worry about.
