ATP Automatic Transmission Modulator Valves

4.93 out of 5 stars 45 Customer Reviews

Improve slow, sloppy shifts with the addition of ATP automatic transmission modulator valves. These valves will keep your transmission shifting on cue, according to load. ATP adjustable replacements allow you to optimize shift points to meet vacuum load and improve gas mileage and performance. A bad modulator valve can be bad news for your transmission. Get control of your transmission for proper shifting of increased or decreased engine vacuum loads. Replace improper working valves with ATP automatic transmission modulator valves.
