Torque converter lockup?
OK, new problem! :confused: For a while my torque converter seemed to be locking at odd times and rpm's. Now, it won't lock at all! My rpm's at say 70 mph are 300-400 rpm higher than when the converter locks! What would cause this? Is it hard on the tranny, and how do I fix it? What rpm should the converter lock up?
The converter is a new PDQ 2400 - 2500 stall!

Connect a test light across ALDL pins A & F (top row each end). It will light until the ECM sends the lockup signal.
If OK, disconnect the wire into the solenoid at the tranny and jumper ALDL pins A & F. Turn On the ignition and verify the lockup voltage appears at the solenoid connector.
If OK, it's inside the tranny.
