2005 Ford Explorer XLT
My check engine light came on yesterday. On the dash it also says CHECK TRANSMISSION and the O/D flashes on and off.

I have a 2005 Ford Explorer XLT, 140K miles, trans fluid has never been flushed, all other repairs/oil changes have been consistent and regular.

Codes:

P0775

P1116

P1703

P1780​

Engine/transmission problem background:

6 months ago, the vehicle had been overheating. I swapped out 2 of the sensors and that solved the problem.

2 months ago, CHECK TRANSMISSION indicator came on the dash, O/D light flashed on and off. Besides that, no problems at all with driving. Just these lights on the dash.

1 month ago, all lights go off. Nothing wrong with driving, no lights on dash indicate a problem.

3 weeks ago, truck starts making a whining noise when I drive. Only when the RPM's go up though, when truck maintains a consistent MPH or dips below that, noise goes away. Only when I put my foot on the gas do I hear this noise.

2 weeks ago, all lights come back on the dash. Tranny starts to slip when I hit 20 mph and 30 mph. Sometimes slips at 50 mph. CHECK TRANSMISSION indicator and O/D flash on and off, then go off completely.

Yesterday, all lights come back on. CHECK ENGINE, CHECK TRANSMISSION, O/D light stays on.

I use my Equus Innova 3100 tool on the truck and get the codes above.

Anyone pull these codes and have these problems?
 






sounds like an engine issue and a trans issue.
P1780 Transmission Control Switch circuit is out of Self-Test Range
P1703 Brake On/Off Switch out of Self-Test Range
P1116 Engine Coolant Temperature Sensor is out of Self-Test Range
