2007 F150 XLT 4.2l v6. Engine starts and revs fine. No movement when in forward or reverse at all. Transmission fluid dipstick is dry. Putting trans fluid in to start. ANy other ideas? Does not feel like the gears engage when I shift into forward or reverse.

 

Tranny will not shift without proper amount of fluid... May want to locate the leak also.

 

no fluid? that's the problem. it's likely there is a leak. have you looked or found one yet?

 

So what we know so far is the fluid level was very low. Then we put some in and it started to work. Then we saw a drip/leak. Saw it leaking from the coolant line. In shop now. Waiting for assessment for sure.
