Default how to ?

hey all well found out my torque converter is locking up all of a sudden didnt use to do this but now it does, came from me hitting the brakes to much one day behind slow drivers doing 13MPH in a 35 MPH zone but anyway....

is there a cheap and easy way i can unlock my torque converter so it wont lockup anymore?? when it locks up i loose alot of power and the whole car starts to shutter and i give it gas to go it wont go till it unlocks and thats pass half throttle..
if i have to drop the pan i will cause im gonna weld a drain port on it so i wont have to keep droping the pan when i wanna change fluid

ive been driving it for almost 1 year and it just started doing this crap, changed fluid and filter but didnt help well might have but you know

btw :i have a 94 z28 camaro not stock but dont know whats in it i bought it this way with all the mods on it

has any ses lights come on? have u scanned for any trouble codes stored in the computer? the converter is locked by a solonoid inside the trans and i think its controled by the ecu.

The torque converter is suppose to lock up when you're cruising in 4th gear. Tap the brake and it unlocks.

Easiest way to make sure your converter doesn't lock up is to put your shifter in D instead of O/D. If it still keeps locking up, you have a problem with the controls. Are you sure you're not feeling it just go into overdrive without the converter locking up? If the converter locks at low speeds, it'll stall the engine when you come to a stop.

yeah it will lock up in 3rd gear to and at low speeds alot and it does stall the engine so i have to press the gas in while im coming to a stopand downshift it manually to 2nd or 1st gaer or it will try to stall out. this has never locked up before the day i pressed the brakes to many times in less then 10 min...if i hold the gas to cruise then barley hold the brake in it will unlock and drives like it use to and it has HP again lol

Are you throwing any codes? The TCC circuit failure is DTC 83 but it won't cause the TCC to lock up - it's that the car can't command the TCC on.
