I have a 700-r4 and today I felt a jerk a few times on my way to work (84 mi. round trip) on the interstate running 75 mph. I thought NO WAY, AC rapid fires W/ 20 K mi. should not be missing. Tonight on the way home, I noticed the shift light going off and on periodicly and my tourque converter was going from lock-up to non-lock-up and back again. WTF? wazup? Is my lock-up solinoid going bad? or the ECM? If the solinoid is going bad, how much trouble is involved in changing it. I've never heard of this problem before of intermitant lock-up/ non lock-up.
Halp me please!!!! PS: No codes or SES light.
