32RH

History

In 1992, the TF999 received an electronic locking torque converter. This new arrangement was renamed the 32RH. The locking torque converter reduces operating temperatures, and increases fuel economy by eliminating slipping at higher speeds. The lower operating temperature prolongs the life of the transmission. The 32RH was used behind the 4.0L I-6 in the YJ, XJ, and TJ. The designation has a meaning behind it.
3 - number of speeds
2 - torque handling (2-300 ft-lbs)
R - rear wheel drive
H - hydraulicly controlled
