Google does not do a good job.

 

lmao
google translate sounds exaclty the same as the first post

 

im not spanish but its close to portuguese...but what im getting from him is that the car seems to be surging or chugging when coming from 2nd to 1st gear, and i think this seems to be happening when engine is cold and it goes away when engine warms up or when he shuts the car off then starts it up again.
also when hes going from 2nd to 3rd gear he is hearing a 'scraping' sound.
its a 2006 auto and no engine light on and oil level is fine

 

i would still get a code reader and see if it pulls anything
how many miles on the car?

 

The car has 140,000 kilometers,

 

The mechanic change the oil transmisión 6 months ago and after the noiese appear, i think that is the oil, i would like to change again and be secure, to buy dextron VI and i change by myself

 

Check the MAF sensor {Mass Air Flow sensor}, a while back my younger brother and I replaced the water pump on my car and we forgot to hook it back up. There were no codes just the odd shifting thing going on.

It might be that the MAF just needs cleaned.

 

Good advice on the MAF sensor.. Ill keep that in mind!

As for Google it gets me by in translation but not perfect. I was hoping one of our Bi Lingual members would translate better! But there is a ton of good advice here :) GREAT site :)

 

When you forget to conect MAF sensor the T/C ligt is on. i dont believe that is the cause. Best Regard

 

i dont think the MAF is related to T/C...
The MAF could be causing the chugging/jerking feeling your are talking about...the T/C problem might be a ABS problem? sensor?
