  • Publication number: 20220137653
    Abstract: A modified cooler bypass manifold includes a manifold body having an inlet conduit, an outlet conduit, a return conduit, a thermal valve bore, a pressure valve bore and an intermediate conduit. A plug may be installed in the thermal valve bore. In another embodiment, a modified cooler bypass manifold includes an OE manifold body, a first inlet conduit, a second inlet conduit, a first outlet conduit, a second outlet conduit and a valve bore. The modified cooler bypass manifold may also include a pressure bypass valve assembly disposed in the valve bore. An OE end cap and retaining ring may be disposed in the valve bore and operably connected to the pressure bypass valve assembly and the OE manifold body.

  • Patent number: 10060526
    Abstract: Aspects of the present disclosure include methods of modifying a transmission valve body to increase a line pressure response in certain hydraulic shift control system configurations. In one example, a Daimler Chrysler 46RE or 47RE transmission valve body may be modified to have a higher and more rapid line pressure increase when the transmission is in fourth gear and when the torque converter clutch (TCC) is engaged. Aspects of the present disclosure also include methods of modifying a transmission valve body to allow TCC engagement in any gear. Aspects of the present disclosure also include replacement valve bodies, as well as kits for modifying a 46RE or 47RE valve body to perform like a 48RE valve body.

  • Patent number: 8794108
    Abstract: A fluid accumulator assembly used with 2002 to 2005 model years of ZF Getriebe's GmbH ZF-6HP19, ZF-6HP26, ZF-6HP32 automatic transmissions, and model years up to 2011 of Ford's 6R60 automatic transmissions. The fluid accumulator assembly includes a piston that can be received into a bore that is in fluid communication with a solenoid-controlled fluid circuit of the transmission. The fluid accumulator assembly also includes a compression spring sized and configured to fit within the piston, and used to provide an urging force to the piston.
