RaceTrans Lock-up kit for TH700R4 and TH2004R**

•  New solenoid;

•  2 terminal normally open 4th gear oil pressure switch;

•  New o-ring for solenoid;

•  Harness with wires;

•  Instructions guide with pictures for easy installation.

When connecting 12-volt source it is best to use a fused circuit with 10-15-amp protection. It is best to use ignition switched voltage for your loc-up circuit. It is recommended not to use the 12-volt ignition coil + side, possible engine misfire can result when circuit closes contacts and loc-up solenoid is activated.

**Transmission pan must be removed to install this kit. Most pans don't have a drain plug, so this is a good time to do a full service and add a couple of other items to really wake this transmission up! Our .521 TV boost valve is accessible at this time, and will increase pump pressure for later firmer crisper shifts. A corvette servo can also be installed at this time to increase surface apply area for 2-4 band apply. This modification gives a much firmer 2-4 shift and has more torque capacity with lager surface apply area. A deep aluminum pan with drain plug can make servicing this transmission much quicker and an easier management of waste oil. The aluminum deep pan gives you an extra 2 quarts and helps dissipate heat when temperature rises under a load.
