Pete Zaria Posted May 6, 2008 Share Posted May 6, 2008 Car: '99 Lexus ES300, 1MZFE VVT-i, 72xxx miles. Problem: VSC and VSC Off "idiot lights" come on, sometimes with Check Engine light, sometimes without. Disconnecting battery for 10 minutes clears codes for a few days, then they return. P0770 seems to relate to the Torque Converter Lockup Solenoid or Shift Solenoid E. My vehicle is shifting fine - I do not notice any hard shifts or lock-up problems. Overdrive works fine. I flushed my transmission fluid (with the recommended stuff) less than 1,000 miles ago. No metal shavings in the drain plug, and it wasn't very dirty. Local tranny shop wants $100 to tell me what's wrong, $300-something if I need a new solenoid. I'm a pretty competent do-it-yourselfer and would like to check this out myself if possible. Any input? Thanks a ton. Peace, Pete Zaria. Quote Link to comment Share on other sites More sharing options...
Pete Zaria Posted May 6, 2008 Author Share Posted May 6, 2008 Come on guys, 35 views and a full day later and no replies? I reset the ECU again and the codes have stayed off for about ~35 miles now. I suspect they'll come back. I'm taking it to the tranny shop and paying $100 for the diagnostics tomorrow unless anyone can give me some input... Please? Peace, Pete Zaria.

gordonw Posted May 6, 2008 Share Posted May 6, 2008 Three possible outcomes would be the shift solenoid in the valve body, the valve body itself, or the torque converter. Quote Link to comment Share on other sites More sharing options...
