Trying to scan a '97 GM W-4 automatic to see why it's kicking the tranny into limpmode. Anyone familiar with where I'd find the link? I've looked under the dash and in the glove box but nothing l;ooks like an OBDII connector.

Hoo boy you going to have some fun now!

The DLC is the 3 pin green connector under the brake/clutch fluid tank. Left side of the dash I believe.

That tranny can be diagnosed with blink codes too. Each DTC is blinked 3 times and the sequence then starts over.

You got an e-mail address? PM me with it and I will see if this trans diagnostics section I copied can be sent to you.
