Electrical problem
2003 Toyota Sienna 6 cyl Front Wheel Drive Automatic 87000 miles

Check engine light keeps comin on. I changed tran. Fluid, spark plugs, front o2 sensor and it is still on. Took it to advance auto and their diagnostic tool states " electrical-shift solenoid". I disconnected the battery and it reset but in traffic it will come on. I've also read about the torque converter being troublesome. Any help would be appreciated.
Thanks.

Hello .. thanks for the donation .. much appreciated

Torque convertor can only really be checked off the vehicle !
TORQUE CONVERTER
NOTE:Torque converter is a sealed unit and must be serviced as complete assembly. Perform following tests to check converter condition. Torque converter and oil cooler lines must be thoroughly cleaned and flushed if transaxle fluid is contaminated.

One-Way Clutch Test
Insert One-Way Clutch Test Turner (09351-32014) into inner race of one-way clutch. Install Stator Stopper (09351-32020) into notch of converter hub and outer race of one-way clutch. See Fig. 4 .
With torque converter standing on edge, clutch should lock when turned counterclockwise and should rotate freely and smoothly when turned clockwise. If one-way clutch fails test in either direction, clean converter. Retest clutch. If clutch fails test, replace converter.

you will need to replace the bad shift solonoid .. a transmission shop will be able to diagnose exactly which solonoid is at fault .. the solonoids are located inside the transmission on the valve body and can be replaced wihout removing transmission from the vehicle !
