Features & Details

  • Makes Shifter Installation Easier
  • Reduces Noise and Vibration
  • Eliminates Need for Silicone
  • Fits T5/T45 and TR3650 Transmissions
  • Fits 1982-2004 V8, 1993-2001 Cobra and 1994-2004 V6
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.

    Shifter Base Handle Gasket - T5/T45

    I try not to give negative reviews, but this product did not impress me. My wife got me an SR Shifter and this gasket for Christmas. I really like the shifter but I did not use the gasket. It did not fit on my 1999 GT vert. If I line up the left side, the right side would hang over and not line up. Only about a 1\16" would sit on the mounting area of the trans, the rest would hang over. Used Permatex. All is good. Going to return it.

    Speed Safety

    Opting to purchase the Shifter Base and Handle Gasket seriously saved time and effort on installing my shifter! By not having to apply a sealant made the install almost effortless, and the piece of mind alone that I have from not worrying about having accidentally dropped some into the transmission is worth every penny!!!

    Disappointed in this gasket

    After my initial installation of this gasket, I would have rated it with five stars however after driving the car I am rating it with one star. The gasket fit the bolt pattern well but after tightening the bolts, it pushed the gasket out with approx. 1/8" visible along each side. It should be noted that this was not the result of over tightening the bolts. The gasket ended up leaking from the front edge so I replaced it with high temp RTV which is working perfectly. With as many problems as are reported here, it makes me wonder why the manufacturer does not use a standard gasket material.

    A must when replacing the stock shifter

    When replacing the stock shifter, or any shifter for that matter. It is well worth it to replace the worn gasket with this piece to help keep the noise coming from the shifter area down a bit. It does help reduce the noise and keep it a bit quieter in the cabin.

    This Gasket is a MUST have with any shifter that you purchase, i drove my car without a gasket for months, when i changed my tranny fluid i bought this gasket with it, and YES there is much LESS VIBRATION going to the shifter, it feels smoother! Thanks A.M.! FASTEST SHIPPING IN THE WORLD

    Do not recommend

    I do not recommend this gasket set, it did not fit properly as everytime I tightend down on the shifter base the gasket seem to squeeze out on each side. I pulled it off and used RTV silicone as I did not want to take any chances on it leaking. Wasted $11.00

    Does not fit!!!

    This gasket is no good. It does not line up with holes on tranny and when tightened it squeezes out the side. Will be replacing with gasket in a tube . DO NOT WASTE $17!! On a good note shipping was fast as normal through AM.

    Not the best gasket

    When i put the shifter base gasket on and tightened it down the gasket just smashed out the edges, i didnt even crank down yet. The material its made out of is poor. after having a leak trying to use this, i ripped it off and used a silicone gasket instead. Much better results

    Must Have

    When I originally put my new shifter in I used a RTV sealant as the casket. I'm sure it worked nice but I just didn't feel like it was doing the job as effectively as a gasket would. I am so happy of my decision to make this purchase. Not only was it much easier to install this but it also had a necessary part that I didn't even think of...it had a gasket that goes where the shifter handle connects to the shifter base. Very happy with this purchase!

    no good

    I bought these in combination with a short throw shifter and put it all together in about two hours. It wasn't hard to install, but the darn thing has been leaking trans fluid ever since. I established the gasket did not properly mate the shifter with the base of the trans. I used RTV silicone as well to keep it from leaking, but that didn't work. It still leaks. I'm gonna tear it apart and redo it with a gasket I'll get form Advanced. AM did their job, but the part didn't do it. I'll always buy from AM, just not this gasket again. Thank you AM for great order handling and shipping. I don't blame you one bit!
