Hi Sir, I am a newbie here. I own a Isuzu Crosswind XUVi 2004 model (Automatic 2.5L Diesel). I got this 2nd hand.

I noticed that the "Check Trans" light is on before I start the engine and goes away after a few seconds and does not appear while driving. I am not sure if this is normal. I brought it to 3 mechanics and did a test drive. All 3 of them noticed that the car was under powered pointing leaning to transmission problem. After this observations I decided to bring it to a shop to have the transmission removed for checking. Below is what they did:

1) Checked and confirmed that the car was not flooded.
2) Drained the ATF and replaced with a new one (around 9L)
3) Replaced the kick-down cable as it was broken.
4) He recommended to change some parts (sorry I do not know what exactly they are).

After spending and doing all the above, the car was running like a charm but I still noticed the "Check Trans" light is still there. Just need some help or advise on what to do next or is this normal. Any advise would be really appreciated.

Thanks in advance!
