I've already done so at several sites and do not accept that a 5 year old cadillac with less than 100,000 miles needs a $4000 rebuild. I understand the code is a circuit problem with the torque convertor lockup stuck in the off position. What needs to be done to correct this problem. There are currently no other codes but I did have a p0741 and replaced the egr valve and pump recently. About 30 miles later the check light came on and this is the code I extracted.

This is common when the torque converter control solenoid goes out here is the location so you can replace it after in which you should clear the codes. Check out the diagrams (Below). Please let us know what happens.

Thanks for the information I got a new solenoid and installed it which was not the easiest but after my buddy helped me I got the job done it fixed it which paying for a new transmission this site is wonderful.

2002 Deville / 4.6L V8 TPI DOHC 32V

I got this car at a really cheap price due to this car having 14 ODB Codes. I replaced approx 500 worth of sensors and now only show these 2 errors.

P0410 Secondary Air Injection System Malfunction

P0741 Torque Converter Clutch Circuit Performance or Stuck Off

I would like to know what is most common cause for these and the approx price to have these issues repaired.

2 Other issues are Fuel Level gauge is not acurate and Check coolent level sensor in expansion tank is faulty.

I can't give you a complete answer but I have the exact same situation you do and have gotten this far. Po410 is the Egr valve located on the top mid engine next to the firewall. Dealer wants between $310 and $370 for it plus labor. Get it online at GM parts-Genuine GM parts for around $210 including shipping. It's easy to replace. Takes about 10 minutes if you have mechanic skills. It fails due to water because the original pump inlet is poorly designed. A new air pump can be found at the partsladi on ebay that includes an upgrade that is less susceptible to water. Cost was $185.00. This one requires a lift or very tall jack stands to get to. It is located in front of the left front tire well behind the front bumper and you need to remove the plastic skirting to change it. Its not really all that hard once you get there but again you need skills or you could screw it up. I'll be watching to see if you get a better answer than I am getting on the po741 code. Dealers, tranny shops all say rebuild it for about $4000. I've owned too many GM vehicles to believe a tranny failure at less than 150,000 miles especially on a cadillac.

I have just had the P0741 code repairs made at a cost of less than $1700. Problem is caused by a slight slippage in the torque converter. If the trans is in otherwise good condition the converter replacement will solve the 741 code problem.
