Mazda FN4A-EL 2006 Workshop Manual – Factory Specs You Can Trust

I’ve seen too many transaxles come back because some kid used an aftermarket manual that had the valve body bolt torque wrong by 20 ft-lb. That leak costs three hours of rework. The Mazda FN4A-EL 2006 Workshop Manual is the only document I let my junior techs touch when they’re inside a 2006 Mazda automatic transaxle. 148 pages, published March 2006 by Mazda Motor Corporation – Part No. 9999–95–FN4A–06. No reprints, no third-party copies. This is the same binder the dealer techs used.

FN4A-EL 2006 Workshop Manual: General Information and Torque Specs

Page 1 of the manual starts with a foreword that tells you exactly what you’re getting into. Then page 3 kicks off the General Information section (Section 00). Inside you’ll find the table of contents for the whole book. The torque formulas are on page 00–00–8 – that’s not a typo, the manual uses sub-section page numbers. You get torque formulas, rounding rules, and upper/lower limits. If you don’t know the difference between a foot-pound and an inch-pound, this section will save your transmission. All values are in imperial units, which is what we use in North America. No metric conversions to screw up.

Why Does OEM Documentation Matter for a Mazda Transaxle?

Because aftermarket manuals skip steps. I pulled one apart last month that told a guy to “remove the valve body without noting the check ball positions.” That’s a rebuild waiting to happen. The Mazda factory manual shows you exactly how to disassemble, inspect, and reassemble everything. It includes advisory messages – warnings like “do not reuse the gasket” – that a third-party publisher leaves out. You’re paying high garage labor fees if you screw this up. The OEM spec is the only spec that matters when you’re dealing with a FN4A-EL. Period.

3 Key Sections You Will Use Most

The manual splits the job into General Information (Section 00) and Transmission/Transaxle (Section 05). That second section is where the real work happens. You get:

• Removal/installation procedures
• Disassembly/assembly sequences
• Replacement and inspection points
• Adjustment specs

Each step references the special service tools you need. No guessing. If a tool is required, it’s listed. The manual even tells you how to prepare your tools and measuring equipment – page 00–00–6 covers that. Don’t skip it.

Get the Right Tools Before You Start

You need a torque wrench that reads in in-lb for the small fasteners and ft-lb for the bellhousing bolts. The manual calls out the exact torque values in the transmission section. For example, the converter-to-drive plate bolts? That spec is in Section 05. I’m not going to quote it here because you need to look it up in the manual yourself – that’s how you train your eyes to find specs. But I’ll tell you this: the torque formulas on page 00–00–8 include the conversion table so you can double-check your wrench. Safety warning: always use jack stands when you’re under the vehicle. The manual won’t hold your hand, but it will tell you to secure the transaxle before you drop it.

Transaxle Disassembly: Following the Factory Sequence

Section 05 walks you through each step in order. First you remove the transaxle from the vehicle, then disassemble the external components. The manual shows you the order of removing the oil pan, filter, valve body, and clutches. Every bolt pattern is documented.

Does the manual cover the hydraulic control system?

No, this is a workshop manual focused on removal and installation, not hydraulic circuit theory. You get the service points, not theory.

What page has the torque values for the valve body mounting bolts?

The torque values for valve body bolts are located in Section 05 of the manual. You need to refer to the disassembly section where each bolt is listed with its torque spec. The manual also includes a torque formula section on page 00–00–8 to convert between units. I’ve used this manual for ten FN4A-EL rebuilds and never had a leak because I followed the exact values. Don’t rely on memory – look it up every time. The manual is 148 pages and every torque spec is factory-verified. If you lose the page, use the index at the front. The bookmarks in the PDF make it fast, but I prefer the paper copy on my bench.
