the shut-off valve on my '87TD went bad day before yesterday so it had to be replaced, which means removing the ALDA unit. thanks to several posts here it was an easy job both to remove the ALDA and then re/re the shut-off valve.

since i had the ALDA out on the bench, i turned the adjusting screw 1 1/4 turns CCW. i have never touched this adjustment before and the tamper seal was still there so it was at the as-built setting. the car has always driven great, at least i thought so.

once everything was back together, the difference in performance and shifting was a big surprise. i was prepared for a little more low rpm acceleration, which was there. i did not realize the ALDA adjustment was going to change how the transmission shifted, which it did and much to the better. shifts are smoother especially between 1 and 2.
