I was just given a 5-speed Tremic from a late model Mustang, I think 2001ish... I was told 1-4 works OK but, the gear box won't go into 5th gear, so I will have to open it up to see what the problem is. I'm hoping it's just a yoke arm broken. (I Hope) I don't have the transmission yet, so when I get it from my friend he will let me know the year Mustang it came from.

I would like to put this in my son/I's 65 Ranchero. Since he drives the highway every day with the Ranchero it would help him with gas mileage. Has anyone done this and if so what special fabrication if any is needed. The Ranchero is already a 4-speed. TIA
