Question about 2002 Cadillac Seville SLS

1 Answer

C/E light on for 1 code P0741, changed TCC solenoid, trans fluid, filter why would the transmission stop going into gear after previously shifting beautifully with no slipping or any issues at all.

C/E light on, got the p0741 code nothing else, put a new TCC solenoid in car, changed trans fluid, filter only did this to get C/E light out for inspection. Did not have any issues with car just needed to pass inspection. Absolutely no issues with cars performance at all only did this fix for inspection. When I took out old solenoid it fell apart in my hands, put car back together, filled with trans fluid, DROVE CAR AROUND MY YARD, put it in park now will not go into any gear, just revs when put in D or R etc. took everything apart again, drained fluid to check my work, all ok put all back together again still will not go into gear. No idea why, car went into gear and shifted fine prior to changing this solenoid etc. after putting together for second time tried to put car in gear, still nothing but trans fluid was not moving when running either. am taking car apart again would like any input. I thought TCC solenoid was really for overdrive and did not really interfere with the gears this one has me stumped being that it did drive a bit after the fix and ran fine prior to the fix

Just because you installed a new part, do not assume it can't be bad. This happens alot with aftermarket parts. When you change just a minor part and a problem develops, good idea to double check both your work and the new parts.

Testimonial: "Thank you for responding. Took your recommendation, thought perhaps it could be a bad solenoid so we took it out and went to the Cadillac dealer to get one that wasn't after market. Put it in and finally realized what the issue is but do not know how to fix it. The TCC solenoid keeps popping out, It does pop in like it should but i guess the build up of pressure or something is causing it to pop out and it will not go into any gear. Remember the old one that i took out, that was causing the bad code fell apart in my hands. Any Ideas would be appreciated."

    Some GM solenoids have been known to come apart in use, such that for the regular shift solenoids there is a repair kit made which comes with a retainer bracket which bolts in to prevent this common failure. Not sure about the TCC solenoid, but perhaps some smart fabricator could make a similar item for your issue. Good luck.

Code P0741 on 01 Explorer had motor rebuilt trans fine put back seems to shift in all gears drive over 45 o/d light blinks. Why?


P0741 ** TCC, internal components TCC slippage detected The PCM picked up an excessive amount of slippage during normal vehicle operation. TCC slippage/erratic or no torque converter clutch operation. Flashing Transmission Control Indicator Lamp (TCIL).

Ok, i am not a european tech so here is the question.. i have a 1998 bmw 528-i that has a trans problem.. p0741 alreadt changed out the solinoid and changed fluid. but i think it got worse it would s


Given what you have said & the metal shavings

I would pull it & rebuild it

Not worth diagnosing the PO741 TCC issue as long as there
is metal, it is thru out the entire unit.

Nothing special about that trans because it is in a euro car

They use Gm Trans & the US Mfg uses Euro, across some vehicle lines & models

I have 3 codes for a 2003 suzuki aerio - P0741, 0742 and 2763. I changed the transmission fluid. check engine light still on


Why would you ask again?

You know enough to go to a trans shop

Now you don't like the advice you got,
so you want us to guess for you

TCC Solenoid?

What was the problem--- Torque Converter Chatter?
There is a product for that
If you change the fluid it might help

Check engine light is on. got these codes P0741, P0742, P2763


Ruled out how?

You still have codes for something

Changing trans fluid only gives you
new fluid,not a fix for anything,just
disapates heat better with new fluid

The codes are for torque converter clutch,so why not
diagnose the TCC Solenoid

Gm Code P0741


If the PCM detects high converter slip when the TCC is commanded on, then a DTC P0741 will set. The following conditions must exist for two times during the same ignition cycle. This code will set for all the same reasons that a P1870 will set: • The TCC duty cycle is greater than 50% • The TCC slip speed is greater than 180 RPM for 7 seconds • TCC slip in 3rd gear on 4L80-E transmissions Known causes for P0741: • Worn TCC valve bores in the valve body • Damaged or worn pump bearing seal • Defective TCC PWM or TCC apply solenoids • Restricted separator plate solenoid feed orifice • Defective converter • Computer reprogram • Channel plate sleeve & turbine shaft sealing ring damage

Vehicle will not shift into overdrive after it gets hot it finally set code 741 tcc code whats that mean


"The PCM controls the torque converter clutch (TCC) solenoid valve pulse width modulation (PWM). The solenoid controls the hydraulic fluid for TCC apply and release. When the TCC is applied, the engine is coupled directly to the transmission through the TCC. The TCC slip speed should be near 0.

If the PCM detects high torque converter slip when the TCC is commanded ON, then DTC P0741 sets. DTC P0741 is a type B DTC.

Conditions for Running the DTC
• No TP DTCs P0121, P0122 or P0123.

• No VSS DTCs P0502 or P0503.

• No AT ISS DTCs P0716 or P0717.

• No TCC stuck ON DTC P0742.

• No IMS DTCs P1820, P1822, P1823 or P1825.

No TCC PWM solenoid valve DTC P1860.

• The engine run time is greater than 5 seconds.

• The time since the gear select lever change is greater than 6 seconds.

• The IMS indicates D2, D3 or D4.

• The transmission gear ratio indicates 2nd, 3rd or 4th gear.

• The transmission fluid temperature is 20-133°C (68-271°F).

• The TP angle is 10-50 percent.

• The engine torque is 43-215 N·m (32-159 lb ft).

• The TCC solenoid valve is commanded ON.

Conditions for Setting the DTC
TCC slip speed exceeds its limit for a given torque for 5 seconds.

Refer to Torque Converter Clutch Slip Speed .

Action Taken When the DTC Sets
• The PCM illuminates the malfunction indicator lamp (MIL) during the second consecutive trip in which the Conditions for Setting the DTC are met.

• The PCM inhibits 4th gear if the transmission is in hot mode.

• The PCM records the operating conditions when the Conditions for Setting the DTC are met. The PCM stores this information as Freeze Frame and Failure Records.

• The PCM stores DTC P0741 in PCM history during the second consecutive trip in which the Conditions for Setting the DTC are met.

Conditions for Clearing the MIL/DTC
• The PCM turns OFF the MIL during the third consecutive trip in which the diagnostic test runs and passes.

• A scan tool can clear the MIL/DTC.

• The PCM clears the DTC from PCM history if the vehicle completes 40 warm-up cycles without an emission-related diagnostic fault occurring.

• The PCM cancels the DTC default actions when the ignition switch is OFF long enough in order to power down the PCM.
