Editing Powerglide (section)

== Types ==
Two primary types or versions of the Powerglide were made. The "Cast Iron Powerglide" transmission introduced in 1950 featured a [[cast iron]] case; after 1963, the "Aluminium Powerglide" substituted aluminum versions of the case and several other parts. Early models were air cooled, and later 60's versions used a fluid cooler in the radiator. The Aluminium Powerglide, and Tempestorque was used from 1962 until it was replaced with the Turbo-Hydramatic series of transmission in 1973. The Aluminium Powerglide is still used today as a racing transmission of choice by many racers mainly for the fact that it only shifts once, and for its extreme durability. It is also possible to purchase all the parts needed to build an Aluminium Powerglide from scratch from most racing parts vendors.
