PLEASE NOTE: This should be used in conjunction with our modulator pressure test kit (see below). It can be unhealthy for your transmission to just "guess by feel" where the T-pin should be turned. If you have ever tried to adjust these modulators out on the road while doing tests, you know how frustrating and difficult it can be to reach up under the car, remove the cap, and try to trun the T-pin. This is designed so you can reach under by "feel" with your fingers and turn to adjust by small or large increments. Comes with full video instructions.
