How do you know if your torque converter is bad

Torque converter is slipping or going bad?

Here are some things happening with my cb7, while I am driving down the road in final gear if I hit the gas the rpms drop and car lunges more forward thats the oposite of what should happen. Then when at like 55 or 60 the car will sometimes shake and other times not.

well thanks for checking this thread out.

mine does that same thing in D4. its almost like an overdrive i think. i was actually in D3 on the interstate and it did the same thing. mine doesnt shake but it does only do this every now and then. not sure but it doesnt bother me. i am curious as to what this is. PEACE

if the torque converter is slipping the RPM's will increase and you won't be going no where. I would check or replace the shift selenoids and/or tranny fluid.

on the vibration ... check your tires.. hard to tell on these things without being there...

With mine, it happened between 40-60mph.

Id be driving along, and id have my foot on the pedal, just enough to maintain current speed. So not on it, but not off it, just keeping it speed, and my RPMs would just a few hundred. I woulnt say it "lurches" but its almost like im mashing the pedal real quick then letting off. First time it happened, the person in my car was like "What are you doing that for?" and i wasnt doing anything at all.

Id say check/change tranny fluid. If that doesnt help, id look into the solenoids.

your torque converter kicks in right after you reach the desired speed. On the highway for instance, you accel. to 70, and then the RPMs drop like 300 and hold. Its kinda hard to explain.

Wow didn't know there were others with this funny anomaly Ill find out soon I guess. lol. I will keep this post updated if I find the prob.

well it was the throttle cable from the intake mani to the tranny that was to short needed to extend it go figure....
