Hi my name is Uncle Joe, I put a 200r4 in my 67 Chevy II Wagon out of a 86 Monte-SS with a 305sb the trans shifts good but no LockUp.I am using a B-M lock up controller .Pat and myself have used it in the past....there is no TCC valve in the VB

What did Pat say, he built my 200r4 also years back, great job by Pat, I have 544hp and 568 ftlbs in front of it in my 67 GS400 now, I too will be checking out how to lock up, I believe Pat told me way back when about hooking up a switch or the BM kit to the 4 prong socket on the side of the trans, BUT the big question is, if you do NOT have a TCC in the valve body, then what is going to lock it up ?? Unless I am missing something.. Johnny J J

Most likely a computer or wiring problem
