I installed an edelbrock performer rpm. Since then, I've lost torque converter lock up. Any ideas. Thanks....Zapr

 

Did you just swap the intake manifold or did you also swap the carb?

Did you reset the TV cable?

 

Swapped intake, kept the q-jet. The throttle bracket doesn't fit the same. Wondering if when I adjusted the tv cable if it pulls out further because the carb sits higher. Would that cause me to lose converter lock up or is it a switch. Thanks....Zapr

 

You need to make sure that the TV cable is set properly. Once you know this is set correctly you can chase other possible causes.

TCC lockup is controlled by the ECM and not the TV cable.

 

Non computer Canadian car. I adjusted the tv but have not driven the car yet. I'll let you know. Thanks for your help.....Zapr.

 

Drove the car. Holds the gear to long. No converter lock up.....Zapr.

 

export models use a vacuum source to determine load for lockup. look for a vacuum line that isn't hooked up or loose somewhere.
