I own a 01 escape with around 110,000 miles on it. I purchased it about 2.5 years ago from a dealership with 98,000 miles on it. The transmission was replaced right before the purchase and came with a 1 yr/12,000 warranty. Recently I have noticed a slipping feeling when it shifts into 2nd gear. I checked the fluid and it was full and looked very well. It was due for an oil change and after reading on here about mercron 5 issues I decided to do the 4qt drain and refill on the trans at the time of the oil change, I did the tranny drain and refill 3 times using just plain mercron (12 qts swapped) The dipstick says mercron only and I cannot see any grind marks where maybe the dealership did the tsb on the fluid issue. After the fluid change, there is no change in the second gear slip feeling. I used my superchip flashpac from my diesel to read any DTC's that may have been stored, I come up with a P0732 code which is second gear ratio error. I called my service manager buddy at ford to have him check my p code, he couldn't cross it with anything he had so I belive the flashpac could be wrong on the p code but right on the diagnosis. Does anyone know what the fix is for a ratio error? I am hopeing that it may be something as simple as an output shaft speed sensor, but I would like some opinions first. Thanks in advance for your ideas.

 

If the transmission was new 2.5 years then it was filled up with Mercon V not Mercon/dexron.
The Esso tranny oil I used has anti-slip stuff in it.. Before jumping or spending try a new oil flush.

 

So the mercron 5 is causing a slip but not burning the fluid? I have no problem with changing the fluid again, but maybe I should get it flushed instead of doing the drop and fill method that I did already. Does the issue and the code seem like the work of mercron 5?

 

How is 4th?

2nd and 4th use the same band, the bands are known to break or crack enough to slip.

 

4th gear seems fine I guess, would that be overdrive? My wife says that since the drain and fill thing I did, the problem is very intermintant. One more flush and maybe the problem will be solved...I hope.
