Question about 2000 Buick Park Avenue
Check engine code with p0137 and p0137pd
Ok, The other day I had a "service Engine Soon" light. The car was shifting really hard, and slamming into each gear. I have found that if I pull over, take my code reader and plug it in, I get a PO742 code. Torque converter circuit stuck on. I proceed to erase that code from the computer, and restart the car and it will run and drive totally fine, as if nothing is wrong. I have been doing it this way for 3 years and the car is running fine to this day. It hasn't cost me a dime in repairs, and I commute 500 miles/week. It's worth a try, because I have heard that if you spend 800-900 bucks to get it "fixed", the problem WILL return some day.

it is part of the transmission torque converter clutch this is inside the bell housing, the trans must be removed to change the torque converter

TCC stuck open in a 4T60E can be either the TCC solenoid gone bad,or the actual TCC valve and bore in the valvebody is worn out.I rebuild transmissions for a living,and i have a reamer for the TCC bore that oversizes the bore,and then install an aftermarket oversized valve to restore hydraulic integrity.What happens is,the valve is PWM (pulse width modulated) which means it basically vibrates in the bore,and strokes many many times per second.Well,all this pulsing wears out the bore,so it must be oversized.But when the bore becomes worn out,sometimes the valve will literally get stuck and won't move.

change your fluid and filter in teansmission WARNING :start car and shut it off just before you do because if you dont you will burn the bands up.I recommend Lucas transmittion conditioner as well.My grand prix calls for sythetic 2003 7 quarts so check with salesman and see what kind it calls for and also count the bolts and pattern before you buy so you make sure you have the right one before you start your project.
