95SevilleSLS Posted May 27, 2007 Report Share Posted May 27, 2007 I took a 200 mile road trip today and recieved the PCM 0741 (I think that's the one anyway) twice. I reset the computer right after the check engine light came on and they were quite a ways apart. Someone mentioned earlier to me about doing something with the electrical connecter, I can't remember exactly what I was supposed to do. I'm thinking it is more than likely something electrical because it works fine for the rest of the time (no slipping) and the fluid is perfect. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...

Ranger Posted May 27, 2007 Report Share Posted May 27, 2007 Well, the good news is you can live with it, because the bad news is that it is an expensive repair. Link to comment Share on other sites More sharing options...
JimD Posted May 27, 2007 Report Share Posted May 27, 2007 The wiring for that circuit goes through the round 20 pin connector located at the rear of the engine almost directly below the master cylinder. Open the connector and check for damaged pins, corrosion, pinched or stretched wires, fluids or anything else that appears to be unusual. If you are comfortable using a VOM, we can provide details.

95SevilleSLS Posted May 29, 2007 Author Report Share Posted May 29, 2007 The code is coming on more and more. Usually it would come on going down the highway, but just a little bit ago it came on in a parking lot. What would I or a tranny shop have to do to get it fixed if it weren't just a corroded connector? JimD, I don't see a connector beneath the master cylinder or towards the rear of the engine. The only connector I see is the one mounted near the strut and it's quite large. It looks like one side of it heads towards the computer mounted in front of the air filter. Would it be this one? -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...
JimD Posted May 29, 2007 Report Share Posted May 29, 2007 All this is the way my '98 Seville is et up and I have no idea if your model is different or not (there can't be much difference). The transmission to PCM connector (C100) is a round 20 pin connector attached to the same bracket that secures the shift cable bellcrank mechanism on the top of the transmission case. You will probably have to remove the engine air intake plumbing to see it; that large silencer chamber will be in the way. Pin U of the chassis side will have 12 Volts with the key in ON or START. Pin T of the chassis side goes to the PCM C1-22. On the transmission side pin U to pin T, the solenoid coil, should show some low resistance with no continuity to chassis ground on either pin. I'm not able to find a spec. for the coil resistance but every solenoid I have checked has fallen between 10 and 100 Ohms. Inspect the connector pins and associated wiring very carefully. Also, be 100% certain you do not have P codes other than P0741. Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...
95SevilleSLS Posted May 30, 2007 Author Report Share Posted May 30, 2007 I'll check the volts a little later on. I don't have any other codes other than that P0741 code. Would the whole torque converter have to be replaced to fix this problem or is there something else causing the slipping? Would a fluid change maybe help? -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...
95SevilleSLS Posted May 31, 2007 Author Report Share Posted May 31, 2007 Still no connector. I pulled the intake off and there is no connector there. I did notice though when I took my intake off that the stupid silencer thing was not connected, it was just sitting there not making a seal. Could it possibly be that the engine wa sucking air in through that hole not cooling off the PCM causing it to act funny? Or maybe it caused erratic conditions because it was sucking in after the MAF? I've heard of people thinking it's tranny problems when it ended up being a dirty MAF. Maybe that's what my problem was. I connected everything nice and tight so hopefully it doesn't come back. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...
JimD Posted May 31, 2007 Report Share Posted May 31, 2007 I'll stand in the middle of Times Square dodging cabs and tell the world there is a connector down there. And you might have found the problem. That would be a good outcome. Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...

I just took her for a test run and I couldn't seem to get it to do it. I drove exactly as I did the other day in the exact same area, but it didn't come on. Could just be a coincidence, but hopefully that was the problem. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...
95SevilleSLS Posted May 31, 2007 Author Report Share Posted May 31, 2007 Tell me if you can see a connector besides the one in the last picture Mr. "There is to a connector there" The only connector I can see is the one in that last picture which is mounted near the strut. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...
JimD Posted May 31, 2007 Report Share Posted May 31, 2007 Must be the difference between years. There has to be a connector; otherwise separating the engine and transmission would mean cutting a bundle of wires. The tip of a screwdriver is sitting on the connector in my '98 model.

95SevilleSLS Posted May 31, 2007 Author Report Share Posted May 31, 2007 Yeah, I don't have that. I wish I did so I could check it, but it's not there. Well, hopefully this intake situation fixed it. If not...I'm not sure yet. I supposed I'll probably take it to my tranny shop. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...
WarrenJ Posted June 1, 2007 Report Share Posted June 1, 2007 Maybe this will help . . . . EDIT: All FWD Northstars are pretty much the same where the basics are concerned. The connector should be right where JimD told you to look. Same on every model year. The attached is from your '02 FSM.
