I understand that the 1962 PG's were air-cooled. Did they have a torque converter with fins? Anyone know about this?

AFAIK, air cooled Powerglides were used in light duty applications only, such as 4 cyl Chevy IIs, for example. They are easy to identify by the large holes in the bell housing area:



1962 Corvette Powerglides did not have an oil cooler, but that isn't the same as saying they are air cooled.

The 'rumpled' (help me with better word here) sheet metal cover on the backside of the converter serves as a fan for cooling. Just like a Corvair PG.

My converter has 3/4" long "bumps" (help me also with a better word) about 1/8" high, spaced 1" apart all around the circumference, mid-point and the center shaft; on the back side of the converter. Do these take the place of the "rumples"?

I re-did the tinypic thing again, it looks like it worked.

What is unclear about the information that's been posted?

Uncle Ralphy

I'm not sure what you're referring to, but if your talking about my post, the first time I tried to post a picture it didn't work. That was the reason for the edit.

My question is, is the converter shown in my picture the right one for a non-external cooled 1962 Powerglide.

I sent you a PM

I do not want to hy-jack this posting but since us with 62 PG's are few and far between we have to stick together.

Can someone take a picture of the rod that goes forward from the transmission to the accelator linkage? Additionally, could you give measurments on its diameter and the between the center of each bend to the center of the next bend?

I have a 62 that was born with a PG. Sometime during its prior life the pg was changed from the aluminum to a 58 cast iron which I intend to remove and sell. I just bought a 62 Aluminum PG with the shifter and rear linkage to the trans. It is missing the front linkage.

Thanks for any help.

Those "bumps" locate the three tangs on each turbine blade to locate them in the converter shell during the furnace-brazing operation when the converter was manufactured.

The '62 aluminum Powerglide was air-cooled, but didn't have the big holes in the front portion of the case; only the Chevy II version had the holes in the case.

Hi Bob: I'm taking my PG out next week. If you don't have a picture of the throttle to trans linkage by then I'll send some.
Do you know if your torque converter looks like the one in my picture with the little bumps or does it have actual fins or does it have the "rumples" as mentioned by 67L36 Driver?

Uncle Ralphy: I look forward to seeing pictures and learning the dimentions of the forward linkage on the 62 PG's.

I purcharsed my 62 trans from a guy in Il through Corvettes at Carlisle. Primarly it had the correct tail shaft, shift lever, dipstick and tube and linkage to trans. Additionally there was a TC and flex plate. The TC appears to be the same as the one you posted earlier. There are 3 seperate rows of what I call dimples. One inside the doughnut hole, one on the fat edge of the doughnut and one on the outer edge of the doughnut. My TC is of the welded type vs. bolt together.

I see your TC has the flex plate mounted. Can you tell me if there are just bolts or botls and nuts to accach the flex plate to the TC.

Additionally, please carefully count the number of teeth on your flex plate and on the bendix gear of your starter. I can not get a clear answer if the 62's had different starters and flex plates vs. 61 and earlier.

Are you going to rebuild your PG yourself or have someone do it for you?

I am learning from talking to different people that these were some pretty bullet proof tranny's and still being saught after by the race crowd.

Yes, they did. 61's all had bellhousing-mounted starters, and only manual transmission 62's did; the '62 with the aluminum Powerglide was the first usage of the block-mounted starter.

I own a 66 with automatic transmission and have a huge puddle of transmisssion fluid on floor. Happened last winter but had new gaskets installed. Transmission was completly rebuit three years ago Do you know why this happens?

Uncle Ralphy

I've had two rebuilds on powerglides and never had that problem. Loose pan bolts? Leaking around the filler tube o-ring?
