Anyone familiar with the notorious 4.6iS torque converter issues? I started getting the TC error a few months ago and I could clear it and would come back a few weeks later but it will now pop back up either the same day it's cleared and driven or possibly the next day. The trans shifts flawlessly and I couldn't tell you there is any performance issues I could notice. I do have a rebuilt 4.6iS TC ready to go so it doesn't sit on the lift more than a day along with real crank seal, rear coolant cover gasket, torque converter seal and new exhaust bolts. Any other experience or recommendations I can use?
