My wife's 94 Model 940 has a AW71L with the Lockup Torque Converter.
I suppose that this type of transmission would be ideally suited for someone who lived on flat ground, but for me, who lives in hilly and mountainous terrain, they can be a pain in the a** sometimes.
The transmission almost never operates in 4th gear. When I'm going up a long hill or mountain road, the usual procedure is either manually lock it out of Overdrive or endure the transmission constantly shifting between 3rd and 5th gear (Lockup), and that's a big difference in engine RPMs.
The only way I can maintain 4th gear is if I start out and slowly accelerate thru the gears. Once it shifts into 4th gear, I can keep it there for a few seconds by holding the accelerator pedal at a certain place and maintaining
the constant...mild acceleraton. If I give it any more gas at all, it will shift back into 3rd gear, accelerate, shift into 4th for a split second and then the torque converter will lockup (5th gear).
It's great when I travel in the flatlands, and the fuel economy is really good as long as it stays in lockout.
I believe the transmission is performing as designed. It would have been better if there was someway to manually control the lockup feature.....sorta like another OD button, but that's too much to hope for I suppose.
ps....I really like the car.
