Ford TR3650 5-Speed Synchro Ring Kits
If your 2000s Mustang’s transmission doesn’t want to change gears, maybe it’s time to install a Ford Tremec TR3650 synchro kit. Allstate Gear has the TR3650 parts you need, whether you’re looking for a complete Tremec 3650 rebuild kit or a single TR3650 synchro replacement.
Ford used the TR-3650 in the Mustang GT, Cobra and Bullitt from late 2001 to 2010. If you have a 2001 model, check the build plate: TR3650-equipped cars have a “K” under the “TR” listing. Mustang TR-3650 synchros differ slightly between 2001–2004 and 2005–2010 versions. Our TR3650 rebuild upgrade kits use the latest compatible design revisions for maximum durability.
