I am rebuilding another 205 (this time a TH400 version) and am doing a write up (to follow-up my last one). This one I plan submitting to the tech section. One BIG problem is I disassembled it today and notice one shift fork was toast and the other should be replaced. I called my local GM dealer who found the part number 3975715, but found it was discontinued. I then went to gmpartsdirect and they say it's no longer available. Can anyone help?
