Well since I cant find the drain plug for the transmission, I am going ot have Chevy do a full transmission flush tomorrow. They said it would run from $149-$179....depending on what the ydo. I dont know what that means. They have flyers all over the place, telling exactly what they do in a transmission flush. So...might as well invest in a preventitive fluid change, than a possible trans. down the road. It runs perfectly, and the fluid is only light brown and doesnt smell burnt, so all new fresh fluid should keep it in good shape for a few more years. I'll keep ya inforamed as to what they do and how much it costs in the end. They said 3 hours to do it, and the last time I had a preventitive thing done, they cut $50 off the price, the yhad like no work for all the mechanics, so it was the owners time to get a 'deal' for once!
