Super Turbine 300

Also known as ST300, 300THM or Jetaway.

Used 1964-69

This was a two speed hydraulically controlled transmission used in some Buick, Olds and Pontiac models.  It shared a FEW parts with the 1962-73 aluminum Powerglide.

Don't confuse this transmission with the Jetaway 315 that was used from 1956-64.  The Jetaway 315 is the transmission most people mean when they refer to a "Jetaway".

Top cooler line is the cooler return line.

Band adjustments:
Low = 3 turns
Reverse = Not used

Gear Ratios:
1.76:1 in 1st
1.00:1 in High
2.76:1 Reverse
