I have a 1998 sl1 vin code "8" The ses light is on and I need to get it off so it will pass ny state inspection. The light will come on and off. Off in cooler weather and comes on after the car has gotten hot after a while. I have got the codes that are tripping it, they are P0706 and P0741 The most trouble I have seen in the shifting is usually into last gear sometimes it won't shift and will run at 2500 to 2700 rpm's at 55 mph. I just changed the transmission fluid, It didn't seem to help much. Any ideas anyone could offer would be greatly apperciated. Thanks
Symptoms are correct for the code. I'd have to look at this more closely=20 but usually the problem that comes up sometimes is the harness plugin at=20 the transmission doesnt make a good clean connection. It is circular and=20 plugs in on top of the transmission below the airbox IIRC.=20
------------------------------------- P0706 Transmission Range Sensor Circuit Range/Performance
P0741 Torque Converter Clutch Circuit Performance or Stuck Off
------------------------------------- Conditions for Setting the DTC P0706
DTC P0706 is set when the PCM has detected an invalid bit pattern for=20 more than 3.5 seconds, twice per ignition cycle.
The difference between DTC P0706 and DTC P0705 is that a possible bit=20 pattern error due to misadjustment could set a DTC P0706.
------------------------------------- Conditions for Setting the DTC P0741
DTC P0741 is set when the PCM has detected the following conditions for=20 more than 7.5 seconds twice per ignition cycle:
The transaxle fluid temperature is above 20=B0C (68=B0F). * No engine or input shaft speed, or signal noise DTCs. * Engine speed is greater than 908 RPM. * Input shaft speed is greater than 224 RPM. * TCC has been commanded ON for more than 5 seconds and there has=20 been no gear change. * Speed difference across the torque converter is greater than 280=20 RPM.
Check the solenoids first. One that controls the shift into 4th gear may no longer be working properly. I posted a simple procedure in Saturn Fans and also in this newsgroup over a year ago. It takes 5 minutes and only requires a metric socket and a Digital Ohm Meter.

I have check the wiring harness, connections all look good. I checked the solenoids as Bob had suggested. All of them read 6.5 +/- .1ohm "cold". I don't know if these would mean that all of the solenoids are bad or is there something else I can check????? Thanks Chris
