If you use an old 722.1 will destroy itself quite quickly. It is a Wx025 transmission, the turbos require an Wx035 to handle the extra torque.
You could try a 722 from an early W116 300SD. B2 piston isn't the usual cause of flaring. That will be a clutch pack or brake band. Then people adjust the hell out of the modulator to delay the inevitable. 300k is pretty good mileage on a turbo transmission. Why don't you just fix your 722.3. It isn't that hard. Or exchange transmissions aren't that costly compared to the labour if will not do it yourself. > On Mar 21, 2015, at 10:22, "arche...@embarqmail.com" > <arche...@embarqmail.com> wrote: > > > Since my 722.315 transmission in an '83 300D is flaring, I've been told it > needs a B-2 piston.
