While driving or parked with engine running the check trans light and the air bag light will come on and flash for about 5 min. The trans will downshift ( manual calls it buckle up) after about 5 min. All appears to return to normal.
what's wrong? What do I check?
Do you

I have a 94 isuzu trooper ls that the check transmission light is flashing. The transmission was rebuilt 1 and 1/2 years ago. I have to manually shift it till it gets to around 30 mph then shifts and operates fine. How do I fix this

transmission light is blinking all the time. Transmission was rebuilt a year and a half ago.

There is a set transmission fault code in the system, get a scan done to read this code and report the code# here for further assistance, start here.

Bought 3 years ago. In prestine shape with all maintance records. Runs perfect, in snow, everywhere.
One problem. Every once in awhile when I come to a stop the check transmission light comes on and acceleration is sluggish. Though, get this, if I turn off the ignition, wait 10 seconds, and restart the check transmission light goes off and auto shifting is perfect for weeks and or thousands of miles. Then all of a sudden, only at a stop, it happens again. And so on and so on.
Waz up?
Thank You

Then turn key on, the trans light will flash the codes. It will start by flashing 12 3 times to let you know it is in diagnostic mode.All other codes will follow.The comp will flash each code 3 times, then move onto the next one.
