Review on Efficient HERCOO Transmission Shift Solenoid Kit with Filter Gasket for Ford Focus/Transit Connect, Mazda 3 5 6 - 4F27E/FN4A-EL Transmission Upgrade by Tyler Parker

So it turns out this rubber gasket is absolutely horrible and creates large gaps and doesn't seal, every bolt was torqued to the required torque and according to the tightening pattern required and because of the gasket my entire was lost Transmission oil and when the oil pan fell back down several bolts came loose at the wrong angle caused by the gasket which was obviously very bad. I don't know how good shift solenoids are. After flushing the transmission fluid twice and draining the sump, replacing the filter and shift solenoids, and using a pinch seal, the car's transmission burned out anyway. Perhaps these parts helped kill the car, or the car was simply already welded and trying to fix it with this kit was futile. In any case, the parts were easy to use, just pull down and twist and unscrew everything except the gasket. not easy to put on, not easy to align, not easy to tighten, hard to tell if you are tightening the screws straight, and in the end just detached and fit nicely in the bin.
