Wenn das Getriebe original Olds ist wird es wohl Roto-Hydramatic sein, hier ein Auszug von wikipedia,
( Link:

Nur dann müsste es ja dem Text nach nach 1961 mal nachgerüstet sein, denn 1956 bis 1960 wurde das Jetaway 4Gang eingebaut.
The Hydramatic underwent several revisions through 1955, before being replaced by the substantially redesigned
Controlled Coupling Hydramatic (also called Jetaway or dual-coupling Hydramatic) in 1956. The new four-speed transmission incorporated a secondary fluid coupling and a pair of sprag clutches in place of the former friction clutch and brake bands, shifting in part by alternately draining and filling the secondary coupling. It allowed the driver to hold the transmission in second or third gear until the maximum allowable upshift points, for improved performance in traffic or in mountain driving, and incorporated a separate park position.
The Jetaway was substantially smoother than the original Hydramatic, but also more complex and expensive to produce, as well as less efficient. In 1961, a somewhat less complex, but also far less reliable
three-speed Roto Hydramatic also dubbed the "Slim Jim" Hydramatic (in which the "dump and fill" shifting principle was retained) was adopted for all Oldsmobiles as well as Pontiac's full-sized Catalina, Ventura, and Grand Prix models, while all Cadillacs and Pontiac's Bonneville and Star Chief models retained the older four-speed "Jetaway" unit (not to be confused with the two-speed Jetaway automatic used in various Buick, Olds and Pontiac intermediate cars from 1964-1969). Both of those Hydramatic transmissions were ultimately replaced by a new three-speed torque converter automatic transmission called Turbo-Hydramatic in 1964 and 1965, whose design was more similar in principle to the Chrysler TorqueFlite and Ford's Cruise-O-Matic than the fluid coupling Hydramatic the "Turbo" replaced.
The original Hydramatic continued to be used in light trucks and other commercial vehicles well into the 1960s. It was subsequently replaced in that role by the Turbo-Hydramatic (THM), whose simplified design was much less costly to manufacture. Despite the name, the Turbo-Hydramatic has no mechanical relationship to the original Hydramatic.
The Hydramatic was a complex design that was expensive to produce. Despite some early problems, it was reliable, and so rugged it was widely used in drag racing during the 1960s. It was not as smooth as some competitor's transmissions (notably Buick's Dynaflow), but was more efficient, especially at highway speeds. The Hydramatic paved the way for widespread acceptance of automatic shifting.
Wird Dir bei dem Problem wohl nicht sehr weiter helfen, aber gute Infos dabei.

Gutes Gelingen,
