Can you use a motor from a automatic transmission in a car with a manual transmission?

Yes. If you have a pickup with a standars trans & a 302 engine & the engine goes bad, you can replace it with several enginesm such as a 6 cylinder 300 CID or any that will fit under the hood. You will likely need to change motor mounts or even move them, or stick a 302 from a Torino ( or whatever car has a 302). If you are running a standard, look into the High Torque cam. They'll deliver more torque & higher MPG. You'll just need to put a flywheel on that is for a clutch &

make sure the crankshaft will take a throwout bearing.

Wow. Wrong, wrong, wrong! The crankshaft, and the throw out bearing have nothing to do with each other. I don't know why he is talking about the camshaft, which operates the valvetrain in the motor. And, he is talking Ford. Now Ford changes EVERYTHING about every couple of years, so bell housings and such, are a pain. If this is a Ford, get the trans with the motor. Chevy, and mopar, no problem. Untill you get into the Hemi stuff for Mopar. You will not have to modify the motor mount situation. Yhere is a little thing called a pilot bearing/bushing that goes in the end of the crankshaft to support the input shaft of the manual trans. If the motor came from a automatic, and you want to put it in a car with a manual, you will have to ad this. The other way around, it wont bother the torque converter, so I would not worry about it. However, you may run into smog laws, so check your state. **
