Yes! This manual fully covers the M5OD-R1HD transmission that came factory-equipped behind the 4.0L SOHC engine in your Ranger.
The reason this matters for a full rebuild is straightforward: the M5OD-R1HD uses different synchronizer blocking rings for 1st gear compared to the standard M5OD-R1, along with different part numbers. The manual calls all of this out explicitly in the rebuild section, including a full synchronizer identification chart that breaks down materials and part numbers by gear and engine size for both variants.
Beyond the synchronizer specs, you're getting complete step-by-step disassembly and reassembly procedures, torque specifications, bearing preload specs, and everything else you need to do a proper rebuild from the ground up. Full wiring diagrams are in there too.
TLDR: For a full M5OD-R1HD rebuild on a 4.0L SOHC Ranger, this is exactly what you need!
