Transmission problem
1993 Isuzu Trooper 6 cyl Four Wheel Drive Automatic 143000 miles

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

It means the computer is seeing a problem witht hetransmission.You can hav it scanned with ascan tool or you can install a jumper wire from terminal 1 to terminal 3 in the data link connector (see pics)

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.
