I have a 645B that the transmision is slipping in both low and high foreward, and a 645 that is slipping only in reverse.  Can anyone tell me if there are new parts available for these transmisions still?  And where might I source them.  They are both allison transmisions, but when I called Wajax here they told me that they call these twin disc transmissions and they no longer handle them.

You may try Kwik Parts out by kingdom City- Fulton Mo; they are a spin off of Oscar Cooke Allis Chalmers construction equipment dealership out of Fulton ,,

Amos - Check the tag on the transmission if it is still on there.  The 645 and 645B should have an Allisson TT  Soft Shift Transmission.  I don't believe that Twin Disc had anything to do with building the Allison Transmission.  

Perhaps these folks could help - see link here:https://catalystpowertrain.com/allison-off-highway-tt-trt-series/
