The T45 in my '96 Mystic Cobra needs a second gear synchronizer and 1-2 shifting fork. Still driveable but only allows slow deliberate shifts to second. My question: Is there a way to swap to a T-56 or TKO and still have a working speedometer? Are there any manual speedo adapters available? If I have to pull the tranny and repair/replace it I feel like it would only make sense to replace it with a better unit but I want everything to work.
