I thought I would post my initial review here for exposure reasons. I installed the transgo shift kit in my 06 outback h6 this last weekend. I have now logged just over 100 miles and this mod is in a word... AMAZING! THE shift response is crisp and responsive. The downshifting is a real hoot too. The tcu is still learning so some hiccups as described by others here is prevalent for me as well. The 4_5 shift in sport during low throttle is still wonky but man what a difference. I was not happy that subaru paired such an efficient engine with such an inefficient transmission, but turns out it's just the shoddy shift behavior that is the issue.
I want to give major props to climber and others whom pioneered this endeavour (lt.columbo, frankster, koukis14 to name a few, sorry if I missed anyone else). The ez30d was a joy to drive before but now has gone to extraordinary. The strength of the h6 is the flat torque curve and now the trans can keep up. Combined with my suspension swap out she is now truly a highway cruiser.
I can't recommend this mod enough. Even if you are stock don't hesitate on this. Well worth the money. Give climber a buzz... Do it.
