I have a 1999 TL with 140,000 miles on it. The transmisssion was completley rebuilt at 111,000. Last night I was driving on the freeway and the TCS and CEL lights came on. Nothing else weird happened. When I got home and turned off the car and then turned it on again, only the CEL light came on. I took it to a parts store and they pulled codes P1739 and P0740. I know these are transmission codes, but my transmission is shifting fine, the fluid was changed 1,000 miles ago, and it is not leaking any fluid. Any ideas what might be going on?

 

there's a site for reading codes... let me find it for you..

 

here it is..
