We all know the 05 and up Mustangs are a great ride.
If you’re a driver and drive it hard, chances are you already broke the 5R55S automatic input shaft, or your about to.
After rebuilding more of these than we can count, we finally found the problem, the factory is making the shafts to the wrong tolerance.
Our custom designed special alloy shafts are built to our exact specs.
We have the only shaft that will hold up against high stall, or triple disc lock up converters.
Whether your pony is stock or modified this shaft is a must for reliability.
At Level 10 we make good transmissions, great transmissions.
