This is Kent's master kit for solving a number of transmission-related shifting problems. Please note it will not solve them all - particularly if your transmission is worn out. This kit includes a new vacuum modulator that will work on even those 722.3 and 722.4 transmissions that have a red or green cap modulator, a complete pressure testing kit that will allow you to test modulation pressure while driving, and detailed video instructions. Watch the attached YouTube video for a quick overview so you can see it IS something you can do yourself!
Product Details
PLEASE NOTE: This modulator will NOT work on the older 722.1 transmissions with red top modulator.

9/2025 Update: Green and Red Modulators are NLA, and we have been informed that they will not be remanufactured. But, do not panic! You may have heard that you must replace your 1981 to 1995 transmission modulator with the correct color top.
