    Review & Install Video

    The SR Performance Shifter Base and Handle Gasket is available for any '82 to '04 V8, '93 to '01 Cobra, or '94 to '04 V6 Mustang with a T5 or T45 or a TR 3650 transmission. If you're looking to swap shifters, it's always a good idea to pick up a new gasket to replace the old worn-out ones to make sure you're covering all your bases for this perfect setup. This is a better option than other silicone or gasket makers because it is way more reliable. Installation is extremely simple and it works for almost any shifter out there with the three transmissions I just mentioned, so expect 1 out of 3 wrenches on our difficulty meter. Swapping shifters is great, especially when you're installing a short throw. But when it comes to taking apart your stock shifter, you'll 9 times out of 10 run into a crappier, ripped up shifter gasket that could be decades old, in which case you'll absolutely need a replacement and some of the alternative silicones or even gasket maker kits can leave unwanted noise and vibration because they are not the ideal solution. They're super temporary. Now this gives you a reliable silicone material, cut for your transmission to eliminate the risk of not applying enough Gasket Maker or RTV properly, and it more importantly eliminates that noise and vibration. It's 1/16ths of an inch thick and the kit here includes both the base gasket and for the handle and it's just under 20 bucks. In my opinion, this is well worth it. You could hit your local auto parts store and quickly pick up a quicker solution, like an RTV or whatever they have available, and you could be spending the same amount for something that won't last as long or be as good of a fix. The installation is beyond simple. I'm for sure giving it 1 out of 3 wrenches on our difficulty meter because it should be to get done in about 20 minutes or so in the driveway at home. When you're swapping your shifters or if you're just replacing a stock gasket and throwing the factory one back on, all you'll need to do is unscrew the shift knob and pop off the plastic trim to gain access to the shifter components. Once the boot comes off, use a ratchet and socket set to remove the old two bolts holding the shifter handle on. Then remove the four bolts holding the base to the transmission. From here, you can scrape off any remaining gasket pieces from the base. Be careful not to have debris fall into the trans, you want to make sure you're catching all that. From here, you can just lay the base gasket from the SR Performance into place, and pop the new or older shifter back on, and bolt it back down. The other gasket goes between the handle and the base where the original two bolts that you removed first popped off. Pop the bolts back on, then the boot, then the trim, then the shift knob, and you're good to go. Just to wrap things up here, if you're the owner of, like I said, an '82 to '04 V8, '93 to '01 Cobra, or a '94 to '04 V6 with either a T5, T45, or TR3650 transmission, you might want to check out the SR Performance Shifter Base and Handle Gasket Kit, which is available right here at

    No More Mess. If you're installing a new shifter in your T5/T45 or TR3650 transmission but don't like the idea of using RTV silicone or gasket maker, invest in a new shifter base & handle gasket set and choose the no-mess, no-fuss installation instead. 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 all T5/T45 and TR3650 transmissions, including 1982-2004 V8, 1993-2001 Cobra and 1994-2004 V6 Mustangs.

    2 Top Rated Questions

    Can I use this gasket with the stock shifter? If so, will it leak since the stock shifter base is much thinner than, for example, a steeda base? Thank you for your time.

    • The SR Performance Shifter Base & Handle Gasket will work with the stock shifter. As long as the shifter base is true, it should not leak.

      A good alternative to the sealer. Make sure to clean the shifter bay and scrape all the old sealer before laying down the new gasket. Great fit

      Shifter seal

      I could only find this from American Muscle. It did the job instead of using silicon. I used silicon last time and it makes it a little hard to get the shifter off. When I have to take it off next time it should come off a lot easier. I like that it's reusable.

      Good Quality

      The gasket is made of good quality! It’s probably not necessary as a type of gasket maker would likely do the job, but I went ahead and got this gasket since local auto part stores do not sell this gasket. It is a little pricey, but I believe it’s worth it!

      Waste of money and time

      I purchased this hoping it would save me time and effort when installing my new shifter. It did neither and was a waste of money. It was difficult to keep in place, did not seal well, and kept shifting when I would tighten. After 1/2 hour, I scrapped it and just used a tube of RTV ($3). That took all of 2 min., and was MUCH easier.

      Big gasket doesn't fit, small gasket is useless

      One side of the bigger gasket is significantly longer than the other, so it doesn't actually seal when you put it on. The smaller gasket I decided to try using, but it just made the bolts slowly back out since I couldn't tighten them all the way down.
