a coworker has offered me a 230 inline out of a 40k chevy2, with alum powerglide for possible use in my '29 A project. now for the question he says it is an air cooled trans. cant remember if this is true ? any info ?
It is very likely a Torque Drive tranny. I have one of such and there are no cooling lines on the case. This tranny has to be shifted manually. Look at it again and see if it has kickdown provisions. If not then I would say Torque Drive.
thanks for the info will have to take a look. were these any good ? had plenty of 60 to 62 chevy cars all were regular 2 speed pgs .
My daughter's 63 Nova wagon 6 had an air cooled powerglide. Worked fine but we went with a fresher freebie from a 67 Camaro when we plopped a V-8 in the wagon. I kept the air cooled jobber. Yes it has holes in the bellhousing but its not shifted manually. It WAS in the HA/GR hope chest but, ..............
...air-cooled Glides were same as others except for the 4 holes in bellhousing for air flow. The fittings are there, usually plug'd, for the cooling lines if you want to run a cooler. Six cyl Glides have a lower fist gear I think, but not really a noticeable thing in a street car, especially a lite car like a Model A. I'd say use it. It should have "powerglide" cast into the case along one side.
The trans I used when I first put my "A" together was one of these air cooled PGs. I think it was from a 63 6 cyl ChevyII. It must have had a lower first gear because it was really easy to spin the tires all the way thru first gear. I unpluged the trans cooler fittings and ran an add on cooler for the trans. The trans was ruined by a flood so I changed over to a TH400 I bought from a friend for $75. The TH400 was from a '68 396 Impala and was built with additional clutch plates like the trans they made for taxis. It has been bullet proof but I still miss the PG! I used to hold the brakes and rev the engine to pick one front wheel off the ground! Oh, to be young (and stupid) again!
Yes the converter is A/C. The out put length is shorter than the others. The out put shaft has a "course" spline.You'll need the slip yoke that goes with it if he has it. You should run an external cooler with it if you can. The low gear in this box is 1.82:1. The 1.82's are very durable except in race applications. Front and rear seals are the same as 350 turbos.
Chevy II powerglides: Air-cooled; they had 4 holes in the bell housing, but also had a cooling vane welded to the torque converter,and the inspection/converter cover worked with the converter vanes to circulate air around the converter. The cooler line holes were plugged; I think to make it functional with an external cooler there was a plugged circuit in the front pump that would also need to be removed. 1.82:1 first gear with the 153 cid 4 banger and 6 cylinder. I think all lo-performance 283 cid got the 1.82 first also. Full lenth 28" in Chevy II/Nova. The Torque Drive in 69-70 Nova/Camaro with 4 and 6 cylinder were essentially a Powerglide with a manual valve body,no kickdown and no modulator. There are minor differences in all of the aluminum Powerglides. The aftermarket has all kinds of performance parts and they even make a complete transmission that's not G.M. at all. I have an air cooled Chevy II Powerglide (no converter or inspection cover/turbine) if anyone would like it-FREE-but it has to be picked up. BUTCH.
You can hook a cooler up to the air cooled PG but only a small amount of fluid will go to the cooler. The oil cooler by-pass spring,oil cooler by-pass valve and the oil cooler by-pass seat are not installed in the air cooled PG's oldjimmy
