700R4 & 4L60E Forward Drum Changes and Interchange Information 1982-2013

Descripción:

I provide a detailed breakdown of all 700R4 and 4L60E forward drums and their respective internals produced starting in 1982 and ending in 2013. I cover all key design features, changes over the years and interchangeability between different years and vintages of 700R4 and 4L60E. This includes pistons, apply rings, backing plates, pressure/apply plates, clutch stack ups and more. I also point out things to watch out for, best practices and considerations for rebuilds as it relates to the forward drums for these transmissions.
