Review on 🛠️ Efficient OTC 7937 Tool for GM Transmission Oil Cooler Line Disconnect by Todd Worley

I've done a lot of work on our CTS over the past few years but removing the transmission cooling lines from the radiator was impossible without the MFG tool. I spent a lot of money and failed. This tool was as advertised. It matched the GM line as advertised, but the line stuck. 120 miles of non-removal made it impossible to remove the lines. Bad GM design doesn't make the product I bought bad! If you have a high mileage GM, remove the lines with the help of a professional!
