99RegalGS Posted November 23, 2003 Report Posted November 23, 2003 Well tonight I drove my friend around in my car to show him how my car has been acting for the past couple of months and he thinks the Torque Converter Clutch is going bad. I think he's right since it only does it when it's engaged. Do these go bad often? Do I need to replace it? Thanks Quote
Justin Posted November 23, 2003 Report Posted November 23, 2003 No sure what your car's doing.... but see if it quits when you apply the brake, as that disengages the torque converter clutch. Quote
Blaze420 Posted November 23, 2003 Report Posted November 23, 2003 I had to replace mine in my Lumina when I 1st bought it. Quote

Yes it quits when I hit the brakes. What happens is the car will shake when it is engaged. The more gas I give the car the more it shakes. I had to replace mine in my lumina when I 1st bought it. Was it hard? Quote
Rob95CS Posted November 24, 2003 Report Posted November 24, 2003 Yes it quits when I hit the brakes. What happens is the car will shake when it is engaged. The more gas I give the car the more it shakes. BINGO! My car does the same exact thing! The harder you press the gas while in 4th, the more violent it will shake until you hit half throttle and it downshifts. Does yours also shake while sitting idle?

Robby1870 Posted November 24, 2003 Report Posted November 24, 2003 93RegalGS, when's the last time you changed your tranny fluid/filter? Quote
99RegalGS Posted November 24, 2003 Author Report Posted November 24, 2003 Ummmmmm, Haven't changed it since I owned the car. At least 23,000 since it's been changed. :oops: I want to change it just need to get fluid, filter and time. This weekend might work for a fluid change. Quote
93Luminanewb Posted November 24, 2003 Report Posted November 24, 2003 I had the same problem with my Lumina when I got it, and I serviced the fuel injectors with this detergent/cleaner kit we have, and the problem went away. Just a thought Quote
my2gxtreme Posted November 24, 2003 Report Posted November 24, 2003 i had this problem when i bought my cavvy. when i would come to a stop it would shake and stall. It would start back up, but as soon as i put it in gear it would stall again. My stepdad(buick tech) just unplugged the tcc plug and i have been driving it like that ever since. Not exactly the best gas mileage but car still runs good none the less. Quote

Thanks The 440t4/4t60 TCCs dont go bad (and if they do its not a trivial fix and you CANNOT unplug it like a 125/3t40) change the fluid/filter TWICE and put on a cooler. many a TSB on shudder during 4th gear TCC lockup Quote
