I drove my F150 5.4 in second gear for 70 MPH and a whining noise came from beneat the truck like from the rear of engine ,Ipull over and stop the engine It will not turn over.

 

Are you serious? 2nd gear at 70MPH? You probably over-revved it....Engine go BOOM!!!

 

ohhhhhh boy....sounds like you burned the engine up!! Second gear at 70mph??????? Poor truck! u killed it :-(

 

The EMM will probably record what you did, so I'd be figuring on buying a new engine out your own pocket. Should be a good learning experience..

 

I thought that even if you shifted into 2nd, or even 1st for that matter, that the engine would shift anyway to prevent such a thing. Plus isn't there a rev limiter built into these things?

I wouldn't doubt if I've hit 70 in second while passing. If I jam on the gas I'm sure I can hear it dropping a few gears and with a 4-spd auto wouldn't that make it second gear?

 

Mmmm... I would play stupid and see what the dealer has to say about the truck not starting.

I know when down shifting the transmission won't shift into the lower gear until you are at a safe speed to do so. However, I believe you may do some damage if you start out in 2nd and accelerate to redline.

Good luck!

 

I was told the transmission frozen up and lock the fly wheel i was told by an ASE.

 

like ATCS says play stupid...likely they will just fix it and not ask too many questions but if you tell them too you will eat the cost

 

Can you tell us WHY you did that?????????????????????????????????????????

 

The engine cannot be over-revved. The computer has a rev-limiter.

The truck and transmission should be able to sustain any governed RPM no matter the gear.

What he said.

 

If the engine wasn't broken in rev limiter or not it could have cooked it.
