Transmission problem
1995 Mercury Sable 6 cyl Front Wheel Drive Automatic
I've a 1995 Murcury Sable Stationwagon, 3.8L 6 cyl. Auto. After the engine is at normal running temp, whenever I come to a stop, the transmission drops out of D. The shifter is still in position, but the engine is disengaged from the wheels. When I attempt to move from a stop, the engine goes zing as if in neutral. However, as the revs fall, the transmission will re-engage (with a clunk) and I can then proceed on my way. Of note, there is no transmission slippage if it is engaged. This is 100% repeatable when the engine is hot. When the engine is cold, there is no issue. From my reading on the net, I'm suspecting a Throttle Control Valve issue. But I cannot find detailed information on how to correctly adjust. Event the shop manual pages I've seen are vague. Would you concur with my assessment? How is the adjustment done? If it is not this, what else could it be?
