Stillen 453336 Transmission Valve Body Upgrade 04-07 Infiniti QX56
Looking for crisper shifts and better performance from your automatic 350Z, G35 Coupe or Sedan? Our 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. Here's how it works: 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 and instructions to return it to us via your choice of 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 your choice of shipping method) for installation.
The slightest damage can render the valve body and the transmission unusable. As replacement valve bodies are unavailable, we insure (as you should when sending the unit in) each valve body shipment for the cost of an installed replacement transmission and limited rental car use.
NOTE: You MUST use Nissan's speciality trans fluid for this transmission. Any other fluid will cause damage!
