I want to try and handle this as soon as possible as I was planning on keeping my new car for some time . What would be the best thing to start doing to check this or fix this ? I read that it can be as simple as tcc solenoid replacement , which I have never done , so how simple this is , is relative . But from what I understand it would mean I wouldn't have to replace the entire transmission which I found can also be another 3000$. Again after the repairs it seems to run beautifully . I drove it from Dallas to Austin and only used about half a tank of gas . Do a search on P0741 - there is a ton of information in the archives. If only the P0741 code is set, there is an issue internally to the trans where the seals in the torque converter lock up apply circuit are leaking and not allowing the torque converter to lock up. If the P1860 code is also set, that code is causing the P0741 code and needs to be diagnosed first - most times, it is the TCC solenoid behind the trans. side pan that it bad. Some have replaced this without removing the trans. from the car. If the P0741 issue is in its infancy, you should be able to clear the codes and it should take several days for it to come back. That should allow you to obtain your inspection. As time goes on, the P0741 issue will cause the torque converter to run hot and eventually, the clutches internal to the torque converter will start to come apart. That happened to my '97 STS and I installed a used transmission since the debris from the torque converter was all through the transmission. I have a thread posted on that project from three years ago. Quote Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
