The Tbird/XR7 M5R2 5-speed manual transmission is known for wearing out synchronizers due to the cars weight and the engines high torque. FoMoCo used to offer carbon fiber lined replacements, which were the original style, but these have become obsolete.
While doing a rebuild, or while doing timely maintenance we always recommending changing out your factory fluid with full Synthetic ATF and a bottle of Friction Modifier for substantially improved shift feel. You will be amazed at how much better your old trans will feel after this swap!
Our "Beefy" polyurethane rear different mount is a HUGE improvement over the weak stock unit with its thin metal and flexible rubber. Wheel hop and general movement of the rear sub-frame starts with a weakly supported differential.
