'82 300TD Automatic Trans. 225k
Bought this car knowing trans. slipped in 3rd and 4th. Found a used trans with 140k on it. The guy installing it has about 200 / 123, 124 and 126's sitting around. He began tweeking the vacumn system and tweeked the slip completely out. He thinks I dont need the tranny transplant now. I drove the car home today and the car accelerates very slow. Once I get to about 40 it will run like a spotted ape. Its just getting the old girl to 40 thats bothering me. Before the vac. tweeking she would jump on 40mph quick. Now it takes along time 4-5 seconds to hit 40. If he tuned the vac. system to get the slip in 3rd to 4th out why is there no take off power. If I have not provide enough information, let me know and I will try harder. Thanks, Treeman

It looks like the wrong torque converter stall speed (to high) was installed in that car. If you think its vacuum, drive it with the modulator vacuum hose disconnected, as A test.

Do a stall speed test, only for a few seconds; to check the torque converter.
Diesel torque converters stall at about 700 to 900RPMs
