My isuzu Trooper wont shift properly to 3 and 4, but 1 and 2 are okay. When i'm driving it need to reach 60 kph before it will shift to third gear and after that fourth gear will not shifted until third gear only and the indicator light on and blinking ATF oil temperature is on. So now I didn't get the code because there is no DLC. Can you please give me data pin to scan the problem of my car?

Hi,

This vehicle isn't offered in the US, but I will try to help. If the indicator light is coming on and flashing, there should be codes. Take a look through this link. It explains how to retrieve OBD1 codes from vehicles made before 1995. Try this and let me know what you find.

Let me know what you find.
