I'm 70 and never saw a G.M. automatic transmisson that was air cooled. Older than me buddy showed me an automatic tranny, 60's he said that was air cooled, he even has the 6 cly. it came with out of, pick up if I remember right. It had no lines to run to a cooler or rad. and it had 2 factory holes in the houseing about 2" dia.. He said it did hold fluid but no cooler lines . He was courious if anybody else had any info? Thanks for any info.
Yeah I had one in my 36 Willys sedan, came out of a Nova only mine was a 4 cylinder trans was a air cooled PG. Motor ran good and trans was great, they do tend to get a little warm and sometimes the engine would stumble but it never seemed to be a problem. Pat
Yes, Aluminum Powerglide (1962 origin) used with 4 cyl and 6 cyl models and also a later variant called Torque Drive (non-self shifting PG). Converter has fins added and 4 holes in belled area of trans case for ventilation. However, not a new idea when introduced. Early Ford O Matic (Borg Warner) designs also used air cooled converters. Perhaps others too, don’t have any info on that. Ray
An old air-cooled Powerglide from a Chevy van. Google indicates that the air cooled 4&6 cyc 'Glides still had the inlet and outlet ports however they used a different pump and had a different 1st gear.
lots of air cooled automatics over the year....Ford and Mopar in the 50s, Chevy in the 60s. Chevy of course did it cheap and simple, they just drilled 4 holes. The others used fancy ducting on the bellhousing.
Is it me of did those older air cooled trans seem to last longer then the newer fluid cooled versions.
Mine is a combo. The trans was a water cooled and was installed where there was an air cooled. With some work the air cooled torque converter was retained because the shop lacked all the conversion parts. Works great.
