Hello guys, I am a new S4 owner, I recently purchased a 2000 S4 Tip. 135k miles, one owner in pretty good condition. My CE light came one and EPC . Well, I went to Autozone, and had them pull ecu code's.
I am getting 2 codes :

1.P0741- the pcm has determined that the voltage signal from the torque converter clutch indicates inadequate performance or a "stuck off " condtion

- That seems very wierd,since the car runs fine (just can use a tune up )tranny does not slip at ALL, and once in a while a get a 2-1 downshift thats a tiny bit noticable.

2. P1633 - KAM Voltage to low.
- I have no idea what this can mean, any ideas?

Like I said car runs perfectly, just a bit sluggish on the bottom end (needs tune up ) I am also guessing the tranny has not been flushed in for ever.
Just incase you are wondering, the car is bone stock. Seems to be in very good condition.

If they haven't then dial the next one until you find someone who has or a dealer that has.

disconnecting the battey to clear out the p0741 code.
Just a guess. Good luck!:-)

Oh-forgot. When the TCC goes many drivers would never even notice if it weren't for the light. Some would even argue that the car is actually smoother without a converter clutch.

you think , I may need a torque converter? The car does not slip at all, drives perfect even if driven hard.

if that's so, then why fix it? or is it just a matter of time before it puts shrapnel in your leg?

Torque converters allow you to have the trans in gear, yet be at a complete stop without stalling the engine. It's fluid coupling that always slips a little. A clutch was added to modern converters to lock it up completely given the proper circumstances, avoiding that gas guzzling fluid shear and reducing fluid temps.
