Hi,
I have 2015 F150, 2.7L v62.while driving my truck would go from 1st to 3rd and stays at 3,000 and will not shift to 4th, also the truck bogs down. I have gotten the truck transmission flushed and they found no metal shaving in the fluid. Has anyone seen or heard of this? And what may I do to solve the issue?

 

Did anybody check to verify the solenoids are all in working order?

 

I have not checked those yet.

 

Make sure you check for corrosion including the plugs outside the trans.

 

the check engine came on and I had the code ran. PO715 Turbine/Input Shaft Speed Sensor Circuit. Can anyone give any pointers to change this out? Or is this sensor inside the transmission?

 

If you look a little closer , it does not specify the speed sensor, but the circuit. This includes checking all the wiring to the trans for any corrosion or damaged wiring or connections. Always pays to check the simple things first.

From the sticker on the vehicle what is the trans code -letter or number?
