PONTIAC1953

Received the extra slant pan today, that the flat pan will add depth to, to have room under the tran's screen filter for the inside heat sink, the picture shows both pans mock up with the outside heat sink.

pictures ???

looking for one pan to buy

I received a Hydra-Matic flat pan from good friend Steve Peluso, to modify my Hydra-Matic slant pan with, going the add the bottom 1 1/2" of the flat pan to the slant pan to make the pan deeper to have room for a 8" x 11" x 1 1/2" aluminum finned heat sink inside the pan, underneath the Hydra-Matic screened oil filter, and another identical sized heat sink to mount outside the pan, this conductive assembly will perform as a transmission oil cooler without the need to plumb coolant from the engine and back to the radiator.

I believe that Cadillac was the only one not going to 14 inch wheels in GM in 1957, 1949 to 1956 Oldsmobile Ninety Eights used 15x6 inch wheels, and late 1970s-1980s Chevy two wheel drive pickup trucks used 15x7 inch wheels, all with same 5 on 5 inch bolt pattern.

the reddish color housing is the 57 Pontiac 9.3, and the carrier is the 3.23 gear ratio I want for the rear end.

I discovered that the rear brake backing plates on my 1953 rear end, are identical to the ones I will need for the 1957 9.3 rear end, so when the time comes, i'll clean and repaint my 1953 backing plates and mount them onto the 1957 9.3 rear end.

good axles, side gears, and spider gears for 1954-56 Oldsmobile rear end, $200.00 plus shipping.

well after several phone calls discussing my trying to change my 1953 Pontiac rear axle housing from 10 spline axles to 54-56 Oldsmobile 16 spline axles with Owner David Winders of Fabcraft Metalworks, he said I should stop what I was doing because he thought strongly that I wouldn't be able to complete the axle swap. It has always been my wish, to find and buy a 1957 Pontiac 9.3 complete rear end having 29 spline axles and side gears, making it pretty much bullet proof, I posted on several Pontiac groups on facebook, that I was wanting to buy a 1957 9.3 complete rear end with 3.23 gear ratio, a Dave Johnson in the Dallas/Fort Worth area responded, he has the one I wanted, and will deliver it to me in November on his way to Ohio, so I will reassemble the 9.3 together, checking what needs to be checked, so I'll be selling the 54-56 Olds 16 spline side gears/spider gears and the axles.

My first manual transmission car was a 1962 Hillman Minx four door sedan, it had the four on the floor, my second manual transmission car was a 1956 Chevrolet 150 series two door sedan business coupe, 235 Chevy six and the three on the tree. I spent 22 years driving semi trucks cross country, was trained with a 9 speed trans, once graduated from truck driving school I was shifting a 10 speed eaton trans, my over the road trainer was surprised how quickly I became good at "floating the gears" which is shifting without using the clutch, I once got to use a truck with a 13 speed road ranger trans, which was like the 10 speed but the last 3 of the 10 could be "Split" by the splitter switch on the shift knob, when the new trucks started coming out with the automatic transmission, I told my Boss to let me keep my assigned truck with the 10 speed as long as possible, knowing eventually the whole fleet would be just trucks with the automatic, finally I had to turn in my assigned truck for a newer one, and was surprised myself how quickly I became used to shifting the automatic, plus the the auto shifter being dash mounted made moving from cab to sleeper berth and vise versa much easier for a big guy. I've been retired from trucking for almost 4 years now, still miss the driving and being paid to see the country.

your 1950 Pontiac is either a Streamliner (fastback) or a Chieftain (notchback), the silver streak emblem isn't the car's model name, but is the name of the Pontiac inline engine and of the long hood/trunk lid trim.

your carburetor metal heat shield is installed wrong, the part with the hole goes over and upwards over the exhaust manifold, your road dfraft tube angles rearwards and clamps onto a bracket that mounts to the rear lower corner of the engine block, are you going to use the 1953 Pontiac power steering pump and related parts ?

True, Cadillac's companion was the LaSalle, which lasted until 1940, Buick's companion was the Marquette, Oldsmobile's was the Viking, and Oakland's was the Pontiac, and Pontiac was the only companion car to replace the division in which it was part of, in mid 1932, it was decided to rename the Oakland Division as the Pontiac Division.

have been researching for rear axle, axle seals, axle retainer gaskets, and axle bearings being shared by Pontiac and Oldsmobile, Pontiac and Oldsmobile shared more rear end parts up to 1952, then for 1953 to 1956 Oldsmobile changed from 10 spline axles and side gears to 16 spline, it appears that the 1953 Olds 16 spline axles have a different part number than the 16 spline axles for 1954-56 axles, my 1955 Pontiac parts interchange manual says that 37-55 Pontiacs & 37-57 Oldsmobiles shared axle bearing #954848, and 39-54 Pontiacs & 39-54 Oldsmobiles shared the axle seal #412111, 1955 Pontiacs & Oldsmobiles shared axle seal #1455257, which I believe is also the Timkin seal #T50059 and National seal #50059, the 1956-57 Oldsmobile axle seal appears to be #568690, the gasket used for sealing the axle bearing retainer to the axle housing for 1937-1958 Pontiacs and Oldsmobiles is #231888. I bought a set of seal #T50059, will see how they fit the 1956 Oldsmobile axles, the #412111 seals are very costly and hard to find.

would like to know if the rear axle seal outside and inside diameter is the same for the 1953 to 1956 Oldsmobile rear axles.

we never call the torus or the fluid coupling a torque converter, the fluid coupling in the Hydra-Matic is very fuel efficent, with only a 2 percent slippage.

Hello, I'm trying to find out who is the Oldsmobile Technical Advisors for these years.

Hello, are the 16 splined 1953 to 1956 Oldsmobile rear axle shafts completely identical in every way ?, I see different part numbers for bearings and seals for these four years.

Bloo was in the ballpark, the outer intake ports that feed fuel to 1,2,7,8 is running too rich a fuel/air mixture.

this is a two door sedan.

Ebay used to be a nice swap meet at your fingertips, and if you wanted to sell something, there was only a small listing fee, now it's FEEBAY, with greedy ebay getting their sticky fingers into everything, listing fees, final value fees, shipping fees, charging taxes if you're buying intrastate rather than interstate, so I flatly refuse to sell on feebay anymore, as for searching, all the unwanted unrelated stuff floods the computer screen that you have no interest in, the -fits helps much less than it used to, have to add several additional -items such as -gates, -dayco, -LS when searching for 1953 or 1954 air conditioning parts, feebay doesn't care how much garbage you have to search through to find what you're really searching for, shame on you ebay.

these early air conditioning systems used a compressor that was always running even when the a/c control was turned off, there would be two sets of fan belts, the shorter set of belts bypass the compressor for winter or cold weather conditions, even in 1953, when the air conditioning option returned for the first time after WWII, the Frigidaire fatboy compressor had no clutch to engage/disengage the compressor, frigidaire used a bypass valve to circulate the freon without going to the rear evaporator/blower fan unit, in 1954 Oldsmobiles with the fatboy compressor, a electric solenoid and a clutch fork mechanism engage/disengage the compressor, 1954 Pontiac with the Harrison designed a/c system was first using a compressor with a modern electric-magnetic clutch built inside the compressor pulley, then in 1955, with the introduction of the frigidaire A5 compressor, Cadillac, Buick, Oldsmobile caught up with Pontiac's lead in having a modern electric-magnetic clutch compressor. here's a picture of the direct drive (no clutch) fatboy compressor in a 1953 Buick factory a/c.
