I'm the one that initially asked about the necessity of removing B1 piston to remove B1 band in order to replace B3 friction disks. I'm in the planing stage getting ready to pull trans in 2 or 3 weeks. Have access to lift and want to do a 2-3 day turnaround. Since it will be out thinking about other seals to do without getting overly involved. Also reason for asking about the B2 piston pin because I might as well replace B2 cover "O" ring while it's out.
Appreciate your help.
