Simple fix with no reaming or special tools required
Installing the ZF5HP-24 Pressure Regulator Repair kit is a simple fix with no reaming and does not require special tools or complete disassembly of the valve body. This Pressure Regulator Repair kit fixes the PR valve malfunction that causes rough or bangy shifts complaints. If you need to disassemble this type of valve body, exercise a great deal of care when removing the separator plate from the upper channel plate as this is where all the small parts are located. Make note of where the small parts go because they are different for each model.
Corrects/Prevents/Reduces:
Runaway pressure that breaks drums
Harsh shifts
Kick-down bang
