700R4 Low/Reverse & Reverse Input Low Drag Steels

Turbulator plates are a design by GM's Hydramatic division, that came out in 1996. By adding holes (of specific design and size) to the low/reverse and reverse input steels on the 4L60E, GM realized these advantages. (1) Improvements in gas mileage. (2) Lower transmission operating temperatures. (3) A slightly quicker reverse engagement. (4) A slight improvement in horsepower and torque to the rear wheels. What the OEM's were trying to do was eliminate the condition known as "after-run". This is caused by the oil creating a fluid bond between the clutch and steel when the clutch pack is in the open position (clutches not applied). The holes in the plates actually prevent "after-run" to a great extent. The holes break up the fluid surface tension that creates the bond by shearing off the excess oil. I use these in all of my transmission buildups, and are included in all of my rebuild kits for the 700R4/4L60E. This is one of GM's better ideas, and will work in any 700R4.
