The TR-3160 transmission, found in high-performance Mustangs like the GT350, Mach 1, and Darkhorse, is designed for spirited driving – but aggressive use can lead to wear and performance issues over time.
At Calimer Transmissions, we specialize in rebuilding and upgrading these transmissions to restore reliability, improve shift quality, and prepare your vehicle for whatever the road or track throws its way.
At Calimer Transmissions, we’ve made the rebuild process as simple and stress-free as possible. Whether you choose to use our Calimer Shipping Crate or ship your transmission yourself, we ensure a smooth experience from pickup to return.
Start by selecting the correct TR-3160 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.
Once we receive your transmission, our expert team gets to work.
Stage 1 Rebuild: Estimated turnaround time: 2-4 weeks (subject to parts availability).
Stage 2 & Stage 3 Rebuilds: Estimated turnaround time: 3-4 weeks (subject to parts availability).
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.
