Stillen Valve Body Upgrade Nissan 350Z 03-05

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 Upgrade we will send you (via overnight shipping) an empty box. This will contain instructions on removing the valve body, adequate packing materials for shipping, labeling and prepaid freight to return it to us via overnight shipping. It is very important that you package the valve body carefully. 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 (again via overnight freight) for installation. The slightest damage can render the valve body and the transmission unuseable. As replacement valve bodies are unavailable, we insure each valve body shipment for the cost of an installed replacement transmission and limited rental car use. With this insurance and 3 overnight shipments, the flat cost of shipping is $150.00 Please contact us with questions. NOTE: You MUST use Nissan's speciality trans fluid for this transmission. Any other fluid will cause damage! **
