Hi new member here i have a problem with my 2003 Cadillac SLS in the morning i saw a oil leak underneath the left front wheel also later on i went to the store a 40 mile drive then when i was two blocks away from getting home i noticed the Service engine soon light come on
now i was told not to drive my car until i took it to the shop but i need a second opinion
PS
when i saw the oil i checked it saw that it was getting low so i poured in a quart of pennzoil fully syntetic
Code i get is PCM PO741

PO741 = TCC stuck OFF.
meaning, a transmission solenoid has most likely failed or is seeing some difficulty.
solenoid costs about $50, labor about 2 days.
BUT .. before you do the shop thing.
1. CHECK transmission fluid level, engine hot, idle, on level ground. If low, fill to level.
2. clear the code and drive it to see if it stays away .. specially if fluid was low.
3. If is intermittent, try a flush, pumping the fluid out, refill and pour a bottle of
Lucas Transmission fix ..
your gamble is that it costs much less than 2 days of labor above, if it works, you are all set,
if not, your back at ground zero.
PO741 = TCC stuck OFF ... sERVICE eNGINE SOON LIGHT on 2003 SLS
