Installed the modulator in my TH400 transmission. The item arrived on time, packaged well, and manufactured well. The modulator and tube did not seem cheaply made. Easy to install, adjust, and still allows solid shifts, installed for over 5 months now. 383 SBC.

Product arrived on schedule and free from defects from shipping. Product fit right in to my 1968 GMC turbo 400 transmission. It replaced the old larger bulky modulator.

Made in the USA great product does exactly what it's supposed to do I would recommend this to anyone that needs an adjustable accumulator for a turbo 400

Upon opening up the modulator, the first think I noticed was the sloppy red/orange paint all over the Modulator. It was on the hose as well. For a company to be proud of it's, "Made in America" badge, you think they would care about it's display. My first impression immediately made me question the quality.Upon install onto my 1977 Corvette, it fit and installed nicely however. The initial settings are a smooth as butter shift point and I do not need to adjust it at all. It seemed to work well and time will tell it's quality. Overall happy...
