I HAVE A 2008 FORD RANGER WITH 101K MILES. 2.3L WITH 5R55E TRANNY.
I PURCHASED THE TRUCK ONE MONTH AGO AND THERE WAS NO ISSUE



THESE ARE THE SYMPTOMS!


Manual 1 works.
Manual 2 works.
Drive Engages... will creep forward if truck is over 3-3500 RPM only.
Reverse Engages... will creep in revese if truck is around 3,000 RPM.
Park- As usual.

IT'S THROWING THESE 2 CODES

P0731-FF
P0733-FF

IF I START DRIVING IN MANUAL 1ST AND MANUALLY SHIFT FROM 1ST TO 2ND TO D IT WORKS FINE UNTIL I COME TO A STOP AND I HAVE TO START ALL OVER. I JUST REPLACED THE FLUID AND FILTER AFTER THE PROBLEMS STARTED THINKING MAYBE IT NEEDED A SERVICE. ALSO CHANGED THE OUTPUT SPEED SENSOR. AND THE FLUID WAS A DARK BROWN/PINK COLOR BUT DID NOT SMELL BURNT AT ALL. TRUCK STILL DRIVES IN D BUT DOESN'T FEEL LIKE ITS COMPLETELY ENGAGED LIKE IT DOES WHEN I START DRIVING IN 1ST

ANY HELP WOULD BE GREATLY APPRECIATED!!!!!!
