Did I screw up?

Did I screw up?
Folks, I think I screwed up ! I changed the oil and filter on my f-150 transmission, but I did not know that I could also replace the fluid from the torque converter, so I mixed new oil with old. To make things worse when I replaced the fluid on the transmission I used the Valvolin transmision oil meant for trucks and suv. I do not notice any difference in the way that the transmission operates but I am worried about any long run damage! Any suggestions would be apreciated!

Thank you for the response WVTRUCKER! the truck in question is also a 2001 f-150 with a 5.4 engine, but I have no idea what kind of automatic transmission I have. The oil I used for the transmission is Valvoline Max Life, its meant to be used on trans that have over 75,000 miles. My engine and trans only have 50,000 miles, but I tow a 22" boat so I figured this oil would fit the bill. Also the oil is for both mercon and dextron III. Would it be a good idea to drain the converter and refill with the same oil?

Your truck has the 4R70W transmission which uses Mercon V trans fluid.

Look on the door jam sticker that has all the trucks info. Under the box marked TRANS there will be a code.
The 4R70w is code U and requires Mercon V
The 4R100 is code E and requres Mercon
DO NOT mix them up, as the 4R70w needs a friction modifier that Mercon V has, and the 4R100 CAN NOT have friction modifiers which is what regular Mercon lacks.
