The 62 Corvette aluminum powerglide did not have any cooling lines for cooling the transmission. The aluminum powerglide was also used in passenger cars and trucks with cooling lines. Am I correct in thinking that GM made two different powerglides one with and one without cooling or was there only one powerglide. When used in the Corvette the cooling lines would have been plugged or capped. Some say that the Corvette powerglige was unique and was not in any way used in other vehicles, infact it had no provision for cooling which means that GM made two seperate powerglides. That does not make sense to me . Please help thanks.

Re: 1962 Powerglide
My knowledge of 63's is better than 62's however I believe that there are several different versions of the powerglide for both years. The Corvette powerglide is designed for the additional horsepower of the Corvette engine. The transmissions without external cooling had holes in the bellhousing for added internal cooling. There are several different tailhousings for the powerglide also. The Corvette shifter fastens to the tailhousing and is for the corvette only. I believe the tailhousing used on the Impala with a floor shifter is longer than the Corvette tailhousing. You would have to go by part numbers per the AIM to be sure that you have the correct transmission for the Corvette. -
Re: 1962 Powerglide
None of the Corvette powerglide's had cooling holes cut in the transmision's bellhousing. The Nova did.Comment

Re: 1962 Powerglide
John,
Taking your comment one step further, did the Corvette main case have holes for the transmission fluid cooling lines, but were they plugged when installed in a Corvette. ???Comment

Re: 1962 Powerglide
Dave; I beleive that and orginal 1962 powerglide had no plugs. That the holes were acually cast shut. I think the 63 started having cooling lines before mid production. I'm open for any correction. johnComment

Re: 1962 Powerglide
The 1962 Corvette Powerglide main case was the same as the Chevrolet Powerglide main case. Both had two small cooling ports. The ports in the Corvette case were plugged - plugs made have an underlined "L" or an "F-C" logo. Except for the early cases, you can see four "+" maks cast into the inside of the bellhousing area. I understand that these were to mark the location for the 2-3/4" holes that were drilled for air cooled transmissions. The front pump in a Corvette transmission contains three valves. In regular Chevrolet transmissions, there is a fouth cooler by-pass valve. Also, the Corvette transmission had the left rear mounting lug cut off for clearance.
