I would be surprised if there are actual differences between the 06 A750F and a 2018 A750F. Visually, from the car-part photos, they look exactly the same.

Not the best comparison, but they look visually the same. Would be awesome if Cruisers and Co could chime in if the 100 series unit MUST be used for whatever reason as the 4runner A750F is significantly cheaper (likely cheap enough to buy, rebuild, modify to work if needed).
All the vehicles that used the A750F (off wiki):
A750F
5 Speed Automatic Transmission(4x4)
Applications (calendar years)
The 4R seems to be the cheapest, along with the Tacomas.
