Upgrades:
  • Low gear set:  Two gear sets are available for the AOD, a 2.46 and 2.84 gear set.  Lower first gear gives your car a harder hole shot launch or can really help out when towing a hill.  
  • Bolt on bell housing:  Whether it is used for competition and requires an SFI certification or you want to adapt to a big block or FE motor we got a bell housing that fits.  
    Accessories:
    • Compushift/TCI aftermarket controller. Electronically controlled transmissions require an electronic control unit (ECU) to shift and function properly.  We recommend two stand alone controllers the compushift from HGM electronics and TCI ez tcu, both have ease of use and adaptability for any project.
    • Transmission coolers:  WPT offers several sized coolers for whatever your load, whatever your horsepower.  We even can make a custom cooler for your confined space or desert runner. We offer standard cooler or those with an integrated fan for spaces with no direct air flow.
      • AN fitting adapters:  WPT has fitting to screw straight into your AOD case and allow you to use a -6AN line for your cooler.  
        • Transmission yokes:  Depending on your application, whether street strip or off road there are several yokes or couplers to choose from.  WPT is a dealer for several suppliers and can get several levels from a basic forged standard u joint size to a fully billet, barrel hardened yoke with massive 1480 joints. 
          • Shifters:  choosing a shifter is one of the keys to defining the style and apeal of the interior of your car.  whether it is a classic street car or a full race car WPT can hook you up with a shifter to suit your needs so you hit every shift on time every time.
            • Dipstick and tube:  Either a standard style tube to give the factory like look or flexible style to allow universal mounting anywhere on your firewall. 
              • Transmission mounts: Available in polyurethane, rubber or solid mounts, WPT can outfit your transmission with a mount that fits your exact car perfectly.
