Newbee 6.0 with Tranny probs

[rustystpsnhd]

Help me folks, I think the clutches and possibly the TC in my stock 5r110 are going. I talked to my ole faithful performance tranny installer, he tells me the 5r110 trannys are good only ever saw one blown, the TC's whatever I go with are great, the problem here in lies with the Clutch packs, according to him, the only reputable clutch packs are by Alto through Suncoast rebuild kit, however, Alto has held off on making the clutch packs cause of problems with them, they've hold off and are R&D them. Any suggestions please help me.
