Cavalier gearbox 2.2 Motor

Friends I do not understand the vehicle was fine, they were made minor repairs and now the vehicle does not make any of its changes only apply the reverse and go without changes .. what could it be .. ??

Check if the hose of the change depressant is disconnected that if it is disconnected does not change and what type of minor repairs were made? Or if you were released by the guayas of the change and you enter a single speed.-

only chain change and change of module .. I get the service light and do not make changes the box ..

The safest thing I leave you or a connector or an empty hose disconnected with the engine on controls if you hear any air aspiration and check that possible mind you can have a disconnected connector if it does not present anything that I told you previously tries to disconnect the battery for 5 minutes to see if you manage to turn off the service of Service and thus the switchboard can reset the errors that the errors that you have accumulated, another question is accumulated? Try and let me know I greet you Alfredo.-

Good thanks friend Alfredo .. I already did those tests, I disconnect the battery and when I turn on the engine the service light returns again and if the kilometer account works perfect the truth I do not understand I hope you can help me ..
