I have had issues with my service engine light. I had the codes checked and what came back was the Torque Converter Clutch and the other code was the Torque Converter Switch. I since then had my Tranny flushed and put in something called LUCAS per my mechanic. Now the light keeps comming back on with only the code for the Torque Converter switch. Please keep in mind the code for the Torque Converter Clutch does not come on any more just the switch. I took my car to AMMCO becasue my car guy is clueless and they told me 2K and I need a new Torque Converter. I told them it was just the switch and shouldnt that be a external sensor. AMCOO said no I need the whole Torque replace or I will break down. Can i get some help on this.

Flushing the transmission was definitely the wrong call. That will never help a specific problem throwing codes go away--or almost never.
Get a second opinion from a quality transmission specialist in your area. That's the best thing to do when the price quoted is this high, and especially for specialized work like transmission work.
If the internal components of the torque converter are damaged, then it will likely require a rebuild or replacement, and this gets expensive very quickly.
