Hello, i have an 04 auto coupe which is also a slap-shift and i was wondering what i can do to improve the shifting between gears. I heard the Stillen transmission valve body upgrade would probably be the best choice and would like to know what you think. In essence, i want to know what i can do to get my automatic to shift somewhat like a manual if its possible.

 

this has been posted like a million times already, TransGo shift kit.

which kit would be best for the g35?

 

nevermind i found the ones.

 

would i need the RE5R05A-HD2?

 

Yes. RE5R05A-HD2 is what you need for your car. - http://www.forgedperformance.com/sto...cat=834&page=1

 

nice. thanks for the link

at what power levels is this recommended? I'm thinking about asking my local nissan dealer if their master tech could do the work for me?...

 

A car that is stock will benefit from it. I don't think there's any limitations for the kit.
