I have a 2000 Dodge Grand Caravan with 85,000 miles that is displaying P0O700 and P0740 codes. I know that P0700 is an information code that means there’s a fault code stored in the transmission control module; this code is P0740, which refers to the torque converter clutch, specifically, no RPM decrease at lockup. My understanding is that when there are problems with the torque converter lockup clutch, there will be a shuddering felt from the clutch trying to engage. However, there is absolutely no shuddering with this transmission, but there’s also absolutely no indication of lockup, either; this van runs perfectly and shifts like glass, just no lockup. Since everything else feels great, I’m thinking the problem is with the transmission control solenoid; does this make sense? What are good brands of replacement transmission control solenoids?
Thank you.
