Hi guys, new here. Got a quick question here, I have a '98 cobra, and whenever I have it in gear and stomp on it, it accelerates pretty nice up until about 4k rpm, after which it acts like the rear end is slipping on some ice, just mostly stops pulling and sits there at around 4-5K...my question is does this sound like the clutch is slipping? I replaced it with a 11" conversion last spring, and have been pretty easy on it, I have a manual clutch cable that needs to be adjusted a bit, but that is it. Could this be a rear main seal leak? or do you think it's the clutch thats worn, any way to tell? Also, the T45 is pretty old with about 125k on it, could the trans be slipping? I've never heard of a manual to slip, but is this possible? Any help here is apreciated!
