While driving went into limp mode meaning I had P, R, N, and second. I changed fluid and filter (atf+4), normal silt in pan no shiny metal. I also put Lucas transmission fix in. Van drove fine for 189 miles then limp mode again, I went ahead and changed fluid and filter, pan filter and fluid were clean. No Lucas this time. Drove fine gain for maybe eighty miles before limp mode. I am mms or in a position to have it scanned for transmission codes. I know when it is going to be in limp mode as soon as the engine starts here is how. As soon as it starts there will be a slow ratchet sound ( for two seconds) two times. I know it is in limp mode. When it is not there is no ratcheting sound, and when I put it in gear it smooth with that normal solenoid buzz click sound. I have found no bad wires connections, or grounds. Relay is good, I have correct voltage at TCM connector pins 8, 11, 60, 59, 19, 20, 15, 16, 17, 56 but not at 9, 57, 47. Wires for those 3 go to 8 pin connector on the solenoid assembly and test good with ohms. Any Ideas?
