replace the trans filter and fluid flush if that don't fix it the torque converter may be bad
first check the fluid level and for trans or trans line leaks

SOURCE: v40 hard to start and will not idle unless I give it a little gas

We had the same problem and found it was the fuel pressure regulator. Upon replacing it no longer gives any hesitation at startup.

SOURCE: idles good, dies when i put it in gear

I had a very similar problem except I would have to throttle my truck just to keep it running. It wouldn't even idle. If I were you check the spray pattern on your fuel injectors. It should look like a nice misty cone. Youy dont want lage drips of fuel, you want a mist. Also cut into your fuel line to test your fuel pressure. It should be around 9-13 psi. My truck had 3psi. I then replaced the fuel pump and the problem was solved. Hope this works for you.

sound like engine overloaded when you over fuel put too much fuel in prevent engine from drawing in enough air to successfully burn all of the additional fuel that is injected in the engine in an effort to pull the load need remove some of the fuel see what happens.

putting it into a gear and hearing a knock indicates that the engine mounts or transmission mounts are broken
naturally if you put it in neutral it will not move as that what neutral is
perhaps the neutral position needs adjusting as it may still be in drive
have the fault codes read to determine any sensor/servo/solenoid faults before spending big money on a transmission

When you get a check engine light it means a fault has occurred and a fault code for that is in memory, now you need the fault codes or codes read to see what is going on and then troubleshoot the system.
