    Default Check Engine Light, Transmission?

    Hope this is the right forum!

    Check engine light came on last night ('96 Z71) while driving. Kept up at 55 just fine until I had to slow to under 20...tried to accelerate and truck sorta sputtered and was only able to go 20-25 mpr (very rough). Went up and over a hill and going down, coasted until 55mpr...truck ran fine again until I had to slow down. Made another attempt at accelerating and truck wouldn't pick up...starting hearing a banging under the hood on the passenger side. Pulled over & got a tow.

    Tranny fluid was lower that expected, replaced fuel filter but still hesitating on the shift. Fluid doesn't smell like the "burnt almonds" as you might smell but engine is a bit louder.

    Any suggestions?

    Default Get the codes

    If you don't have a code reader, borrow one from a local parts store (Autozone) More info will make for a better diagnosis.

    I really miss the old days when all you needed to get a code was a paper clip a pen and paper.

    Now days with all computerized equipment in the running gear you got to be an engineer to fix something.

    And we all know how much I dislike engineers.
