The control system is intermittently malfunctioning and the following are possible causes and corrections for this condition:
" External valve body assembly (shift solenoid "2", shift solenoid "3", shift solenoid "5") - verify that all solenoids respond electrically. If there is no response, perform electrical diagnosis. If there are no electrical concerns, remove the solenoid assembly, and inspect the solenoids, "O" ring seals and bores for signs of damage and/or missing seals. If solenoids responded electrically and there are no bore or seal concerns, replace assembly due to a possible internal mechanical concern, and retest. If a concern is still present after replacing the solenoid assembly, replace the control valve body assembly.
" Internal valve body assembly (M1 shift valve, M2 shift valve, U1 shift valve, U2 shift valve, shift pressure relay valve) - remove valve body assembly and inspect all listed valves and/or bores for wear, scoring, foreign objects and/or contamination. Replace control valve body assembly if necessary.
" 2nd coast clutch, 2nd clutch hub and 2nd clutch sprag assembly - remove torque converter assembly, fluid pump assembly, 2nd coast clutch, 2nd clutch hub and 2nd clutch sprag assembly. Inspect all related parts and repair as necessary.
I believe trouble codes should be stored in the TCM and you need appropriate scanners to retrieve them
Try Autozone to see if their scanners can come up with anything. They provide free scanning services.
