Transmission first lost 3rd gear; after a couple months of daily driving it lost 5th and 1st as well. Reverse became extremely difficult to engage. I had the transmission replaced with a used transmission and a new clutch kit (tried to solve a separate issue of the clutch slamming when engaging, no matter how slowly it’s let out; failed to fix that issue). Mechanic notified me that the old transmissions clutch was still in good shape. Huh interesting... However this issue of lost gears was solved with the transmission replacement. It’s been 30k miles since.
