Hi,
Both the 4R44E and the 5R55E were used in the ranger. The 5R55E was used with the 4.0L engine. According to the label you sent me, the letter D indicates the truck originally came with the 5R55E. I did a little more digging, and it appears that the transmission case was used for both model transmissions.
Based on that, I feel that is the likely model transmission in the vehicle and what it came with. I hope that helps.
Listen, if you come across a specific model and year that you question, let me know and I see if it should fit.
Let me know if this helps or if you have other questions.
Take care,
Joe
