Does anyone know if there is a transmission relay or fuse for 03 deville? If there is what is the location? I seea fuse in the boxin the engine bay it is 10 amp it says trans? Is that the only one? are there relays? One would think that there should be something more than a 10 amp fuse, wouldn't you. Any input on this?
What kind of issues are you having? There's only one fuse, marked TRANS, #13 in your underhood fuse box. The TRANS fuse handles TCC PWM solenoid and shift solenoids. All others are managed by PCM.
if you have any codes - post them here -
ALONG WITH THEIR DEFINITIONS -
----------------------
if you have P0741 by itself - without P1860 - the problem is worn seals -
and the ONLY way to fix the problem is to drop the trans -
if you have BOTH - P0741 AND P1860 -
the TCC solenoid is defective and can be replaced WITHOUT dropping the trans -
