Good point about knowing what gear its in, I guess the pcm wouldn't know that...but then again the vacuum actuated TCC doesn't know what gear you are in either it just works off of vacuum. I'm hoping the pcm can calculate off the vacuum (map sensor) just the same. As far as VSS goes, I plan to purchase from here...
