Ive had the same "double click" feeling in my 3550, but it starts to happen after everything gets hot, and only from when i'm at a dead stop. My mechanic tells me its the synchros and to try Redline fluid. I know that Tremec doesnt recommend it, but my guy has been using it in Cobras etc... with no problems. Going to try it as soon as time permits.
