Had some noise from my tranny shortly after buying my Cobra new; they replaced the entire clutch assembly and the TOB guide tube retainer under warranty. (TSB 04-13-4). So now 40k later I need to replace my TOB, I'll be using the FRPP HD version. Anybody know which tube Ford used when doing the TSB replacement- McLeod, Lethal, or ? Just wondering if I need to have one on hand when I pull the tranny. (in case they used the stock Ford part and it's weak sauce.)
