bjd618 Posted June 18, 2015 Report Share Posted June 18, 2015 Ive got error code p0741 with no symptoms other than that it is a little hard to shift out of 1st after the car has been sitting for a while. There is also a trans fluid leak that seems to be coming from near the drivers side wheel that leaves puddles when the wheel is turned hard in either direction or if one wheel is higher than the other. Its an 01 Seville STS with 115,000 miles. Does this sound like the typical bad solenoid or TCC? Do you think the tranny leak is unrelated or is it connected to the code? Ive also got B1983, B1390, and p0440. Thanks for any input. Quote Link to comment Share on other sites More sharing options...
Cadillac Jim Posted June 18, 2015 Report Share Posted June 18, 2015 P0741 TCC System Stuck OffB1983 Device Power Circuit LowB1390 Device Voltage Reference Input Circuit MalfunctionP0440 Evaporative Emission (EVAP) System The first thing that the factory shop manual (I'm using the 2002 model year here) says is to check the transmission fluid level. The next thing to check is the transmission cooler lines to the radiator. The transmission cooler is in the left tank. The FSM says to make sure that the lines aren't kinked or pinched. The P0440 means that the EVAP system isn't holding pressure. This can be a loose or leaking gas cap. Check all the lines on the EVAP system. The other two codes are probably from a low battery sometime in the last couple of months.

barczy01 Posted June 18, 2015 Report Share Posted June 18, 2015 You have the typical 3rd clutch housing bushing worn. It's not a axle seal and don't replace it. The bushing on the clutch housing wears away causing excessive axle travel and fluid leakage from the drivers axle . The 741 are turbine seals on the upper valve body plate for TCC lock up. I charge 1500$ with a converter while I am doing head gaskets on the car. Quote Link to comment Share on other sites More sharing options...
bjd618 Posted June 18, 2015 Author Report Share Posted June 18, 2015 So the leak and the p0741 are not related and fixing one doesn't fix the other? I'm not looking to put a whole bunch of money into this and may just get rid of the car if getting every thing fixed is going to cost thousands and thousands of dollars.

KHE Posted June 19, 2015 Report Share Posted June 19, 2015 The leak and the 741 code are not related. The trans. has to come out of the car to fix the P0741 code. While it's out, the 3rd clutch housing bushing can be replaced. It shouldn't cost thousands...
