Chaffee Transmission Questions

[Malcolm Towrie]

Hi, I got one of the GM Hydramatic transmissions off a M24 Chaffee apart and I have some questions:
- the tranny oil cooler has large ballooned spots in the cooler plates shown below. The cooler is on the suction side of the oil pumps so sees very low pressure, going on below atmospheric. Anyone any idea why has this happened?

- the front clutch pack is smoked including the aluminum apply piston. One of the return springs punched a hole through it. Who sells hard parts like this for these old trannies?

- who has Chaffees who could answer questions on these trannies?

Thanks,
Malcolm
