Review on 🔍 Enhanced Performance: ATD-5550 Automatic Transmission & Engine Oil Pressure Gauge Kit by Dana Schmidt

I needed this to help me with my first 4L60 (700R4) restoration, it was the best price I could find for this tool. Comes with several adapters to connect to the gearbox test port. I actually left it plugged in for a couple of weeks while I fixed some valve body issues. Having not used the more expensive ones, I'm not sure how this one compares, but I can say it did the job and I'm not sure I could have successfully recovered without it.
