1990 M30 transmission problems

[sadM30owner]

planetary come apart in trans. and damaged case. rebuilder got a new case,and rebuilt trans.It lasted 300mi. He said a clip broke and clutch pack come apart. He rebuilt again at no cost to me. It lasted 200 mi. and it's broke again. No overdrive,no reverse,can't even push car backwards. Drive is the only gear. 1 & 2 as if e-brake is on. Trans. is noisy. What would be causing this problem? It seems to shift fine upon leaving the shop.
