I've had transmission overhaul kit performed Oct 2007 on 2001 Cad Deville: incl upper/lower valve body w/solenoids, imput carrier, converter @ 77K miles. My check engine light came on a wk ago at 91K miles 3yrs later. Went to local parts store for free ck engine diagnostic and my veh coded at P0741. Return to transmission shop to be told that teardown is needed to find the problem and the code was reset. Went to Cadillac Dealer/Goodwrench repair facility for diagnostic workup and was told of only one code P0507 w/no check engine light on. The printout has PO 507 100 needs IAC Vale and Serv. Asked about hx of codes, I was told of no history of code P0741 detected. They indicated the replacement of IAC valve and Throttle Serv is needed and veh will not pass emission since computer has these codes. Please help, i'm confused.
have the same problem?
