We have a 1990 240 wagon with an AW70 transmission. Last month we got off the highway, stopped at a the light. When the light turned green the car refused to go. Initially I thought we had a major leak but this turned out not to be the case. Under the car, on the left side of the motor, just near the motor/tranny joint there are three green wires dangling. I have spent a bunch of time under the car and can't find out where they go. Are they perhaps part of a sensor. The only manual I currently have (Chilton) doesn't have a very good wiring section. I am wondering if either of the governor or pressure modulator sensors are not connected and therefore not contolling the tranny. Any other suggestions?
