So, I'm in NC and no help on actually getting the work done, but I can offer you hope that there might be someone to do it if you are not going the DIY route. My Nissan specialist mechanic did the TransGo for me, have had no issues whatsoever. But I found a stupid low miles pampered coupe (26.5K four years ago) now at 44K when I did the TransGo several months ago. They did not require a rebuild. Flushed and refilled with BG fluid (yes I am aware of the "don't flush" advice but they convinced me); BG provides lifetime Plan 1 (50K and under miles) coverage of $4,000 for repair/replacement as long as you maintain the 30K mile service interval. It is transferable (though I have no intentions of ever selling this car). So there are people out there that can do the work that are not "transmission shops." Good luck!

Thanks a lot for the insight ! If I every work up the courage to do it I'll definitely do all those suggestions.

I did the TransGo kit few weeks ago and now i regret it.
I did clear all driveability settings in ECM and TCM so the trans can relearn itself. It shifts normal below 3-4k but it kicks so damn hard at wide open that it literally moves the rear end of my G to the side. Chirps the tires and if i'm upshifting on a slight turn, the back slips left or right depending on the curve. But the worst part of this mod is when doing 65-75 in 5th on the highway and suddenly flooring it.. First BANG, then second BANG and finally the right gear in and it goes (2-3 sec lag).
I followed all the steps and drilled the right holes with the right bits (measured with digital caliper) so i don't know what the hell is wrong with it (besides the mod) but it really sucks..
The manual shifter is no better either, it works the same sluggish way as it did before this mod but that THUMPING and BANGING inside the trans when downshifting under full throttle is just horrible.. I've looked at few valve bodies with the same BOSCH unit but can't find the same E A plate stamp, not sure if it matters and no idea if all 2nd gen RE5R05A valve body separator plates are the same.
So, if anyone has a UNDRILLED valve body separator plate, let me know. It's stamped E A 2007 G35 5AT.
