Transaxle ?

I have a transaxle from an old AMF lawn mower. Not sure of the year but the transaxle is a 3 speed oil filled one with a side input pully. My ?'s are 1- how strong are these (will they take rpms) 2- can they be welded 3- Not sure if it has this setup but if the brake setup was disconnected and say you were going 20mph in 2nd gear can you shift on the go to 3rd with out losing speed and have no issues getting it into 3rd (kinda like a standered car tranny)

I think arild has or had an AMF 3 speed that had a pulley swap. Hopefully he'll see this post & chime in.

*poof* Someone called my name?? haha, yah ive got an AMF tractor. Transmission is pretty heavy duty. The only down side to it is that the frame isnt very solid. It handles a pulley swap really well, but seems too complicated to weld the rear axle. You are able to shift from 2nd to 3rd on the go if you just half clutch it, but you cannot down shift cause itll grind. Works really well if you have a gas pedal too. Well good luck and lemme know if you have any other questions
