Lock out convertor

How can you tell if your transmission has a lock-out transmission?

Do you mean lock-up? Usually this is found on overdrives. When the converter locks up it may feel like an extra shift and the rpm's will drop.

when the torque converter locks up you will have a direct connection between the engine and trans.....so go about 60 to 70 mph and in just about any trans that has a lock up you will have reached the speed for lock up and punch the gas pedal and listen/watch rpm for the engine to rev with out a noticeable increase inthe mph...if the engine revs you do not have a lock up unit

Thanks for the Info. Yep :o You are right I did mean lock-up. Can you tell me if this is a standard type of convertor for a Corvette? I have a 81 with a 5.7 in it. 3 Speed trans. Tim

It probly has the lockup converter in it, get under there and look on the drivers side of the tranny, there will be a 4 pin connector there if it has it.

Easy way = cruise at a steady 50 mph on a flat road. Don't remove your foot from the accelerator and lightly touch the brakes - enough to actuate your brake lights but not the brakes. If you have a lockup converter, it will unlock and your rpms will rise for a second and then drop back. If nothing happens, either you do not have a lockup, or the brake switch may be out of adjustment and you are not locking up like you should.
