98 SC1 Tranny shift issue - Page 2

Ok here is the code from the SES when I ran the ODB II check.

0741 - Came back as a "Torque Converter Clutch Circuit Performance or Stuck Off"

I hate to ask, but what the h@#$ mean?

Ok, went to the local Autopart store, purchased the new $10 ECTS, installed it and made my morning commute; minor, minor kick on 2nd but smooth the rest of the gears. How the H3ll does that happen?! I'll keep an eye on the rest of the drive but I don't get how the ECTS is tied into the tranny.

The ECTS is VITAL to many sub systems of the car including air/fuel ratios, idle control, timing, fan operation, emissions, and even tranny operations such as shift points and Torque Converter lock up points.

I would not remove the PCM B fuse in the under hood junction box...this will reset the PCM and revert it to its stock shifting tables. From here it will relearn your driving habbits and may improve your tranny performance.

Make sure the connector to the ECTS is clean and corrosion free also.

So here we are almost 1 year later. Car just threw a P0773 "Shift Solenoid E Electrical" at me. Is it time for a new Valve Body? Or what's the point now?

How many miles have you put on the car?

More then likely this is the line pressure solenoid. Its easy to replace, not sure on price though. If you want to replace the whole valve body, then there is a guy Special Forces who every one buys from. His rep is outstanding.

Also make sure your electrical system is working well. 14V at idle is what you should see at the battery. These cars are very sensitive to voltage diffferences.
