STUDEBAKER AUTOMATIC TRANSMISSION

THE principles of design and the operating characteristics of the Studebaker automatic transmission are presented here.

The basic transmission design consists of the following major elements:

1. 1.
   A single-stage, three-element torque converter completely fabricated from stampings.
2. 2.
   Two epicyclic single-planet helical gear sets.
3. 3.
   Two gear-type oil pumps.
4. 4.
   One multiple-disc clutch.
5. 5.
   One single-plate disc clutch submerged in oil for direct drive.
6. 6.
   Three band-type clutches with suitable servo mechanisms.
7. 7.
   Three sprag-type freewheel units.
8. 8.
   One valve block assembly.
9. 9.
   One centrifugal mechanical governor.

Tests results and performance characteristics for the transmission are discussed briefly.
