Features & Details

  • Makes Shifter Installation Easier
  • Reduces Noise and Vibration
  • Eliminates Need for Silicone
  • Fits T56 Transmissions
  • Fits 2003-2004 Cobra Mustangs
No More Mess. Upgrading the shifter in your T56 transmission and don't like the idea of messy RTV silicone or gasket maker? You'll reduce the chances of having a stuck bolt or and eliminate the possibility of getting silicone into your transmission by buying this gasket set. It's a smart investment to protect your transmission and it makes shifter install easy.

Eliminates Noise & Vibration. If you use silicone to install your shifter, you can get unnecessary noise and vibration. Using a complete gasket set will reduce the amount of vibrations coming through your transmission into your shifter. Plus, it can eliminate the possibility of metal-on-metal contact if you don't get a complete, thick, evenly distributed layer of silicone. And let's face it - who has time for that?

Easier Removal. Using a shifter base and handle gasket is a smart choice when you have to service your transmission, too. Trying to get your shifter off to get into your turret is a headache if it's on there with silicone. With a gasket it's easy to remove and even reuse when re-installing your shifter.

Application. This SR Performance Shifter Base & Handle Gaskets are designed for use on the T56 transmission, including 2003-2004 Cobra Mustangs.

          Best gasket out there!

          I know this is just a gasket, but I've installed so many shifters before and this time I decided to invest in this. Makes a difference for just 16 bucks. No tranny noise. Smooth install. And better seal than tradition gasket and gasket makers

          makes the noise stop

          Great gasket for reducing that shifter noise and heat generated by aftermarket shifters. Most people use gasket maker to seal the shifter but if you can spare the extra cash use these gaskets. You will be very pleased!

          Was super easy to put on, the only hard part was scraping the silicone off. Made my shifter quieter.

          Great Gasket!!

          The gasket went on with no problem. With other gaskets sometimes the holes dont line up, this didnt have any issues. Also works better than the RTV no mess and it takes a minute to put on.

          T-56 Shifter Gasket

          I purchase a MGW shifter which sent RTV gasket sealer but chose to us this Gasket kit instead. It was easy installation with no mess of silicon. The only thing I noticed was that the gasket squished out on one side the shifter base and not the other. So far I see no leaks and it does quite down the trans beeter than my Tri-aax shifter on my other mustang.

          T-56 Shifter Gasket

          Great gasket that really does help quiet down trasmission and shifter noise! Worth the money and can be easily removed unlike silicone.
