Code PO750 4R70W Trans
 

Hi all my 2001 F-150 has this code. I changed the shift solenoid but still get the same code and the OD light is blinking. if anyone has had this problem any info would be greatly appreciated.

I found a fuse blown but the OD light is still blinking and the trans seems to be shifting harder than normal and down shifting more quickly.

thanks in advance for any help

Did you change the correct solenoid?

Yes I believe so. I have recently taken it to the ford dealer and they cant figure it out either. they had to contact ford motor co today they are thinking broken wire...

ok truck fix....the harness on the firewall was on the egr pipe and melted some wires the intermitate problems were cause by grounding wires on the egr pipe.
runs great now
