STR Posted December 20, 2002 Report Share Posted December 20, 2002 torque converter shutter. TransGo has a valvebody fix for this. Quote Link to comment Share on other sites More sharing options...
msvestka Posted December 20, 2002 Report Share Posted December 20, 2002 Next time you are on the road and your car starts to do this, just touch the brake with your left foot, this will disengage the torque converter, see if the shudder goes away.

89Cutlass Posted December 20, 2002 Author Report Share Posted December 20, 2002 Yea i just drove it and it is torque lock shutter. When i tap to the brake it disengages the torque converter but only for a second unless im holding my foot barley on the brake then it will stay unlocked. Its not extremly bad but very anoying. What can i do to fix this ive seen some tranny fluid aditives that claim to fix this. ?? Thanks Craig Quote Link to comment Share on other sites More sharing options...

MotorCityMike Posted December 21, 2002 Report Share Posted December 21, 2002 thanks alot can you tell me anything about trans go and how much and were can i contact them about this ??? thanks Craig tranny shops should be able to get it for you I used to work at a tranny shop and we used to use ShudderGuard. It worked 90% of the time. Other things you may want to possibly consider is the TPS sensor. If it is bad, the ECM will get false readings that will cause TCC lockup. The first thing you should do is scan the car with a good real-time scanner such as a Snap On or MAC. Quote Link to comment Share on other sites More sharing options...
89Cutlass Posted December 22, 2002 Author Report Share Posted December 22, 2002 I put some lucas tranny treatment stuff in and its made a big difference but still a little shutter. Its weird cause it just started doing it after i changed my wires. Quote Link to comment Share on other sites More sharing options...
chevyguy3100 Posted December 22, 2002 Report Share Posted December 22, 2002 Sorry I didn't catch this earlier, it is a wire or coil pack. I have had the same exact problem. At least one plug isn't firing cause of an arc. You need to figure out which one and either replace it or wrap it up in elec. tape. The reason the tranny shudders is b/c the engine and tranny are so fine tuned that it knows it's supposed to shift but it's short at least one cylinder, so it doesn't have the torque pressure to throw it to the correct gear. I feel your pain. I hated it cause I even knew when it was going to shudder. Hope this helps! ~josh Quote Link to comment Share on other sites More sharing options...

91GranSport Posted December 30, 2002 Report Share Posted December 30, 2002 All right, I had a stupid question for you guys. I have a 4T60. How do I know when my tranny's torque converter "locks-up"? Is that when it hits over drive? Quote Link to comment Share on other sites More sharing options...

1trucavalier Posted January 7, 2003 Report Share Posted January 7, 2003 TCC lock up switch could be bad. Go out to your car and look above the vac mod and pull the tcc connector out, take it for a drive, if it stops doing it then you switch may just be bad. The switch cost $8.50.
