while driving the other day, I hit a small bump in the road..disengage

Customer Question

while driving the other day, I hit a small bump in the road. this caused the transmission to disengage. The car was still running, but when pressing on the "gas" no forward movement.
The transmission will not engage in any gear (forward or reverse)
I checked and the U-joints are still in place, no visible leaks for fluid and fluid looks clean & full.
what could cause this to happen in an automatic transmission with less than 40k miles.

When you press on the gas pedal, does the engine rev up but the truck doesn't move? Like being in neutral?

Or does the engine just not do anything?

I apologize for the delay.

Based on your symptoms, it would be impossible for me to identify what the problem is. Either something has failed in the transmission, or all of the fluid has leaked out, or the transmission solenoid has failed.

Since you've already checked the fluid you'll need to rely on electrical and hydraulic pressure testing to find the point of failure. This is not something you're going to be able to do on your own.

You're going to need to tow it to a Ford dealer or a repair shop that specializes in transmissions. Sorry for the bad news.
