So the check engine light came on. :gaah:



2003 3.8l 131,500 miles


I do not think it's nothing major drove it a few miles , I do not hear any difference in the sound of the engine.

But it came on for a reason. Anyway you can get the car scanned and let us know the codes?

 

[00impala123]

Why are you telling us this, then stating its no big deal and not providing information as to a code that came up?

p0741 code (1 of 1)


P0741 CHEVROLET - Torque Converter Clutch Circuit Performance or Stuck Off
seem to shift okay.. I'll call the Transmission shop since it's under warranty. I hope that warranty was transferable.. :bang:

Your TC clutch is stuck off? Have you noticed a gas mileage drop? You should. Depending on how often you highway drive and that clutch locks up.

getting about 17-city (speed limits around here are 45 to 65mph)

I don;t drive on the freeway since the city speed limits are all ready freeway speeds
example 55MPH to 65MPH on larger street

But sometimes you can hit all red's, that could eat up a lot of gas.
If I did take it out on the open freeway, I would expect to get around 25 to 27MPG.


not scared of the freeway or anything I taken a car to 90-95mph (keeping up with traffic, beats getting rear ended)on the local freeway in Los Angeles
I watched as a cop passed me up as well!

My point is the TC clutch locks up at cruising speed to improve gas mileage. Basically both halves spin at the same rate, when the clutch engages, preventing lost kinetic energy through the transmission fluid in the TC.

I'll get it checked out I just got to find the warranty receipt for the transmission since it's under 12mo/12k miles on the rebuilt one it has

it's like 80 miles away

Light went off should I still get it checked out? very long drive

 

[Ejbiers]

Yeah if you got a warranty the code should be stored in the computer as long as you didnt erase it. I would definitely get it checked out. Its cheaper to check now than blow up a torque converter out of warranty

yeah the code got erased accidentally so I'll have to wait for it to come back on

There are solenoids that can be replaced in the transmission. I don't think it's uncommon for them to fail on the 4T65E. The TCC is one of them. Hopefully your warranty covers it.

yeah the transmission feels heavy when pressing the gas I could only barely get it to 2 or 3krpm (if I am lucky)

gas pedal floored


rev's up fine in park.

I can feel a drag

Get it fixed before you cause more problems.

just got to wait for the light to come on again.

seems to be working now got it into the 4-5k range with ease
I all ready know it's not good to take it into the 6k rpm range as that could damage the engine.

got it to 80mph without much trouble on a local back road.

 

[Ejbiers]

I wouldn't wait for the light by then it could be to late and they will be telling you that you should have brought it in sooner so they aren't gonna cover it.

 

[auntjemima]

They don't need a light to diagnose problems. A light is something to tell the end user to have it checked for issues. Any decent mechanic can diagnose an issue without a little light holding their hand along the way.

I agree with auntjemima and furthermore you can always take the tech for a ride or have him tke it so they can see the problem first hand.
