Home / NISSAN / 350Z / / Stillen Automatic Tranny Valve Body Upgrade 350Z/ G35

Looking for crisper shifts and better performance from your automatic 350Z, G35 Coupe or Sedan? Our new valve body upgrade is the answer. This unit will increase the power handling ability of the trans as well as firm up the shifts and improve performance. Shifts 1-2, 2-3 and 3-4 are substantially improved. Our extensive modifications include upgrading springs, revalving and machining the stock unit. Better performance than any other unit!

**Please note - THERE IS NO CORE PROGRAM. This upgrade is performed on the valve body already inside your transmission. You must remove your valve body and send it to us for the upgrade. Once you have purchased our Valve Body we will send you a empty box with instructions on removing the valve body and adaquate packing materials for shipping. It is very important that you package the valve body very carefully and purchase shipping insurance. The slightest of damage can render the valve body unuseable. Once we receive the valve body, we will have the valve body upgrade finished within 2 days of receiving it and will send the completed unit back to you for installation.**
