Easy to unplug - works great - BUT... Sorry, it won't help with notchy 2nd shifts - certainly not if you're already grinding!
Just jack up the passenger side (the connector is on that side of the tranny, fairly high up the side looking from the MT82 under-side) and use 2 jack stands. Keep the floor jack up too - just to be safe!
I just tie-wrapped the cable+connector so it wouldn't just be floating freely.
