You can send in your valve body and have it modified, or order a valve body if Brauer Engineering has a core for your transmission - see tables below.

Currently, all orders are made by e-mail correspondence to office@brauerengineering.net.  In the e-mail, include your engine size, vehicle body and shift RPM - such as '1986 Fifth Avenue 318 2 barrel stock' or '1970 Charger 440 with Hemi Grind Cam', and the year the transmission was made - see the Transmission Identification page.

3rd to 2nd downshift sensitivity
The sensitivity of the 3rd to 2nd gear, and the 2nd to 1st gear downshifts are adjustable by adjusting the kick down linkage, but the 3rd to 2nd gear hysteresis is determine by the shift kit.  Hysteresis is the tendency of the transmission to stay in a gear after it has shifted.  When hysteresis is low, sensitivity is high.  The hysteresis/sensitivity of the 3rd to 2nd gear downshift is determined by the power, weight and gear ratio of your vehicle.  To know whether or not you should get high or low 3rd to 2nd sensitivity, just ask yourself if you have to push the throttle more than one third the way to the floor to get moderate acceleration.  If your vehicle is a 1970 Dodge Dart (light car) with a stock 318 V8, high sensitivity 3rd to 2nd is recommended.  For a 1968 Plymouth Fury (heavy car) with a stock 318 V8, low 3rd to 2nd sensitivity is recommended.
High sensitivity is much more fun to drive on a high performance car.  But if the sensitivity is too high on a low horsepower or heavy vehicle such as a motor home, the vehicle will down shift at 55 on the highway, just trying to climb a moderate hill, when it would be better for it to stay in high gear.  So if you find that you have to push the gas pedal more than half way to the floor just to maintain highway speeds up moderate hills, you should get low 3rd to 2nd sensitivity.

Full throttle automatic shift point RPM can also be somewhat adjusted upward if desired.

Note:
A904 and A727 valve bodies can be interchanged by making a modification.
A500 and A518 valve bodies can be interchanged by making a modification.

Rear wheel drive transmissions, made from 1966 to now, can benefit from installing a valve which pumps the fluid in park. Installing this valve allows a hole to be drilled which guarantees that fluid will flow through the torque converter even when the transmission is hot and the RPMs are low - such as at a stop light or in reverse.  This is a must for transmissions with lock-up converters, because fluid flow is what prevents the lock-up clutch from partially applying causing the converter to go bad.
