Ok so I have had this problem for sometime now, since I bought the car. I have googled the problem and replaced the sensors related to the problem I'm having and the problem is still there, The problem which is at about 60-100 km, while driving the rpm's will bounce forward and back/flutter/surge. What I do is let off the gas and problem goes away/ or accelerate and problem goes away. From my understanding it may be one of two problems but I could be wrong, one is which is the TC, later 4T45Es have a PWM (pulse-width modulated) torque converter lockup as opposed to an on/off solenoid. It's supposed to make TC lock undetectable. Just wondering do I replace the Torque converter or solenoid(TCC solenoid). Thanks
have the same problem?
