The Tremec TR-3650 is a 5-speed manual transmission found in various Mustang GTs and other performance Ford vehicles from the early 2000s. While it delivers a solid driving experience in stock form, the TR-3650 can suffer from issues over time — such as notchy shifting, worn synchros, gear grinding, or input shaft problems, especially under aggressive driving or added power.
That’s where Calimer Transmissions comes in. Our TR-3650 rebuilds are designed to restore and enhance performance by addressing common weak points, improving gear engagement, and reinforcing the transmission to handle higher torque loads. Whether you’re restoring a daily driver or building a street-strip machine, we’ll make sure your TR-3650 is ready to perform.
Start by selecting the correct Tremec rebuild package based on your model year and desired stage. During checkout, you’ll have the option to customize your build with additional upgrades to fit your performance goals.
We’ve made the shipping process simple and straightforward to get your Tremec TR-3650 transmission to us for a rebuild.
Once we receive your transmission, our expert team gets to work.
Please Note: Turnaround time varies, but expect a minimum of 2 to 4 weeks.
Once your transmission is fully rebuilt, we carefully package it and ship it back to you, ready to install and get you back on the road or track.
We’ll reply as soon as we can.
