White93z34 Posted March 13, 2005 Report Share Posted March 13, 2005 alrighty this ongoing problem has been agrivateing me to no end, anyhow. on the highway my car will sometimes surge really strange. heres the deal, my cruise control is inop at the moment, i even disconnected the cable from the TB to help narrow the problem down. when cruiseing from 50-70ish on the highway and holding my foot on the gas to maintain speed the rpms will be around 2000-2500~ and out of no where it seems it will kick up to 3000 and drop back and keep on doing that as long as i hold my foot in that place on the throtle. i kinda want to say its a TPS, but i'm not sure.

maybe2fast Posted March 13, 2005 Report Share Posted March 13, 2005 it sounds like the torque converter is unlocking and there is a switch for the TCC and the brake lights (there maybe two seperate ones) It is under the dash and is controlled by the brake pedal, it may just need to be adjusted. Because when you hit the brake on the highway the TCC will disengage and if that switch is freakin out it it maybe your problem. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 20, 2005 Author Report Share Posted March 20, 2005 i have no idea where this switch is located. anyone know where for sure it is. i tried hitting the brakes on the highway when its in the middle of doing that it seemed to make no difference. my boss feels it may e the TCC solonoid or something like that and mentioned that i may have to pull the side pan off to replace it. i'm really in the dark with this problem.

rudefyet Posted March 20, 2005 Report Share Posted March 20, 2005 i had a similar problem caused by my alternator but unless your voltage is going crazy, it's prolly not the case Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 20, 2005 Author Report Share Posted March 20, 2005 no my voltage stays about the same no matter what. also when its in the middle of one of its episodes if i drop it back to D from OD it will stop but it feels like it almost wants to do it still.

1990lumina Posted March 20, 2005 Report Share Posted March 20, 2005 I'd say check out that TCC switch under the dash...sounds like something that is relatively easy to rule out and a inexpensive fix... I know sometimes my TCC wouldn't lock up..but I later discovered it was a temperature related issue..so I just the motor warm up longer..maybe a sesnor is saying your temp is to cold and it unlcoks the TCC..but thats just a shot out in the dark..sounds like a very wierd issue though Good luck with finding it out man! - Jeff L.

maybe2fast Posted March 20, 2005 Report Share Posted March 20, 2005 the TCC switch is right by the brake light switch under the dash on the brake pedal stem. The TCC switch should have a vacuum line going to it and see if they are adjusted properly. Don Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 21, 2005 Author Report Share Posted March 21, 2005 i looked at it, the Brake light switch works fine, and off the brakelight switch is a vaccum line, all seems to be in order up there. would changeing my TPS be a good idea? i'm really getting lost/fed up with this problem.

maybe2fast Posted March 22, 2005 Report Share Posted March 22, 2005 the brake and TCC should be seperate switches Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 22, 2005 Author Report Share Posted March 22, 2005 where exactly is the TCC switch, i looked up there about as far as i could see, i'll have to get a flashlight and check. Quote Link to comment Share on other sites More sharing options...
maybe2fast Posted March 22, 2005 Report Share Posted March 22, 2005 right above the brake light switch Quote Link to comment Share on other sites More sharing options...
3.1LUMITIC Posted March 23, 2005 Report Share Posted March 23, 2005 the TCC switch is right by the brake light switch under the dash on the brake pedal stem.

You push dont the brake when its on an it breaks the vac. seal and shuts the cruise off :?: Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 23, 2005 Author Report Share Posted March 23, 2005 there is a vaccum line comeing off the brake light switch too, i assume thats for the cruise shut off. as far as the TCC switch, i haven't got a flashlight so i could look up there yet.
