Black & Red Stripe Vacuum Modulator For TH350 & TH400 Transmissions - New Replacement

About This Product

If you're dealing with shifting issues on your TH350 or TH400 automatic transmission, this vacuum modulator might be the fix! It's a brand new part from Rostra Precision Controls (under the CT Solutions brand). It's got that classic black body with a red stripe. The part number is 51-0020, and it interchanges with numbers like 44160B and 35820H. It's made in the USA and is considered a vintage part, which is awesome for older car restorations. It comes with a manufacturer's warranty for peace of mind. Installation is pretty straightforward if you're familiar with transmission work – just swap out the old one. This little component controls shift points based on engine vacuum, so if your transmission is shifting late, early, or harshly, this could be the culprit. Brand new in packaging, ready to get your classic ride shifting smoothly again.
