Automatic trans steal plates?

[ss3011]

The surface finish has a lot to do with how the clutch applies . Grooved plates , will hold oil and slow down the apply . Quickest shifts will be with flat , smooth steels .

BTW , If a steel plate has heat spots on it , then throw it away . If you measure the thickness of the steel plate at a heat spot , compared to a non heated area , it will be thicker . Those heat spots are actually showing a change of metallurgy of the steel which swells the metal . If you glass bead the steel , or sand it , it doesn't really fix the problem of a hot spotted plate . Those swelled areas will shorten the life of the clutch plate , which will be running on those high spots . Best to have a nice new flat , and smooth plate .

Thanks for that info. I am installing new steals and leaving them as out of the box. The scotchbrite is to remove the glaze from the reaction plates that are not readily available for these transmissions .
