I recently, about 700 miles ago replaced my transmission with a tci super street fighter transmission and a tci street fighter 3000 stall converter. the other day while just cruising on regular streets i got a blinking o/d light and check engine light. i read the codes and got a p0740 and p0743 code. my car still feels like its driving and shifting normal. anyone ever had an experience with this? thanks in advance.

P0740 is a code for an open torque converter clutch circuit. Check your connection at the trans, and check to see if you pushed out a terminal in the connector at the trans. Also could be a loose connection inside the trans pan. There is a wiring harness inside the pan too.
