2000 daewoo nubira 4 cyl. sedan..Then is lite ON the check engine.

Customer Question

I have 2000 Daewoo Nubira 4 cyl. sedan CDX Automatic Transmission.
The problem is some time when I driving and chaging from first speed to second speed, the transmission is jumping. Then is lite ON the check engine.
If I stop and I turn off the engine and then I turn ON the engine is OK, the transmission is not jumping. Also is OK if I reset the computer and check engine lite is OFF, but after few miles is the same problem with the Transmission.
