Allis-Chalmers 808 GT II transaxle ID--Whatizzit?

[totallymopar]

I have an Allis-Chalmers 808GTII,circa around 1976-82.has 8 HP B&S engine and 3-speed+reverse H-pattern transaxle. I've never seen a transaxle like this.(photo included).Its oval shaped,and rather flat,like a fat pancake,sits pointed vertically at an angle,and offset from center. A 9" pulley mounted on the shaft which comes out the side.I can't see a tag or label to ID it--coated with greasy dirt. I want to know who makes it,and what gear ratio it has,so I can add the appropriate pulley to it. Would like to do around 20+ mph with it.

Same as the Simplicity 1680454 model wise.

IPL does not indicate who made the transaxle so very carefully clean the dirt and grease off to reveal the tag. A lot of the parts from Briggs are not available.

That trans was made by simplicity I dont know the gear ratio

That transaxle is most likely a Peerless—they made a lot of those for garden tractors back then. Could be a model like the Peerless 600 series, which fits the shape and setup you described. Gear ratio is probably around 8:1 to 10:1, depending on exact model. To hit 20+ mph, you'd need to upsize the engine pulley quite a bit—but keep in mind, those old transaxles weren’t really built for speed, so go easy or it might not last. Might be worth cleaning it off to find the model number stamped on the housing.
