ZF Friedrichshafen 12 AS 3002 S 2008 Parts Catalog

Some aftermarket parts catalogs give you a list of numbers and leave you guessing which seal goes where. That doesn’t cut it when you’re rebuilding a 12-speed ZF gearbox for a Cummins-powered truck. This ZF Friedrichshafen 12 AS 3002 S 2008 Parts Catalog is the factory-printed reference that came from Friedrichshafen itself. 53 pages of exploded views, material numbers, oil grades, and amendment tracking. You need the exact oil capacity? Page 2 says 13 dm³ – that’s 13.7 quarts. The oil grade? TE-ML02. Not a suggestion. It’s the spec. Miss that and you’re buying a new transmission.

Oil Capacity and Grade: Factory Specs on Page 2

The OCR excerpt from this catalog lists oil capacity for the gearbox at 13 dm³. That’s 13.7 US quarts. The oil grade permitted is per TE-ML02. If you’ve ever had a transmission fail because some aftermarket manual said ‘use any 10W-30’, you understand why this matters. This catalog also tells you the number of gears (12), the color (jet black, RAL 9005), and the painting standard (ZF Standard 915 W). When you’re ordering seals or gaskets, you cross-reference the material number from the assembly group pages. Page 3 shows the assembly group overview with material numbers like 1329.004.014 and 6009.097.087. That’s how you get the right part, not a guess.

Assembly Group Overview: Finding the Right Part

Page 3 of this Parts Catalog gives you the assembly group overview for the 12 AS 3002 S. It lists positions, material numbers, names, and VKF incidence factors. For example, position 105.a1.01-1 shows VENTILBLOCK with material number 1329.004.014. That’s the valve block. Below it, position 105.b3.01-1 lists a 20-pin connector (6009.097.087). The inspection program (6009.397.501) is also listed – part of the 12G OD PAK9. If you’re troubleshooting a shift issue that points to the valve block, you pull that material number and order the exact ZF part. No aftermarket substitute. The catalog also tracks amendment numbers – note amendment 001 on page 2 for the use case. That tells you what engineering changes have been applied to your specific transmission variant.

Transmission Variants and Attachments

This catalog covers the 12 AS 3002 S specifically for CUMMINS INC. The transmission variant is listed with no units attached, and there’s a note on the emergency steering pump (without groove). If your unit has a PTO or other attachment, you need to check the ‘ATTACHM.VAR’ line. The catalog lists document references for the gearbox assembly (1328.600.015) and technical cover sheets. You also get the coding for outer and inner conservation (KA1, KI1) and the conservation specification (ZFN 916). This level of detail tells you exactly how the unit was shipped and stored. If you’re rebuilding a transmission that sat for years, you want to know what conservation treatment it had.

Inspection Program and Amendment Numbers

On page 3, the inspection program is listed as part number 6009.397.501. That’s the program that was used to validate this transmission at the factory. If you’re performing a rebuild, you should be aware that the amendment service number (000000144856, 000000144857) links to the test and assembly instructions archived by ZF. That documentation is not included in this parts catalog, but the part numbers point you to it. This catalog is strictly a parts reference – not a repair manual. Pair it with the actual ZF Friedrichshafen S 1115 TD 2009 Parts Catalog – OEM Factory Specs if you need a different transmission family, or the ZF Friedrichshafen AS 1310 2011 Parts Catalog – OEM Transmission Components for later AS series units.

Why ZF OEM Documentation Beats Aftermarket Copies

Aftermarket parts catalogs take a scanned PDF, strip the color, and sometimes renumber the pages. They’ll miss amendment numbers or crop the part number columns. This catalog is a direct rip from the ZF Friedrichshafen AG digital archive. Notice the copyright on every page: “All rights reserved by ZF Friedrichshafen AG, even in the event of applications for copyright.” That’s the real deal. The ‘Information only, not subject to the amendment service’ notation tells you this is a snapshot from December 22, 2008 – but for a parts catalog, that snapshot is what you use to verify which parts were fitted at production. If you’re sourcing a replacement valve block for a 2008 build, the material number on page 3 is the one.

3 Reasons to Use This Parts Catalog for Your Rebuild

First, you get the correct oil capacity and grade without guesswork. Second, every part is linked to a material number that ZF still recognizes. Third, the assembly group pages show the physical arrangement of components so you can identify what you’re looking at on the bench. Don’t rely on the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide for a ZF transmission – that’s a different machine entirely. For the 12 AS 3002 S, this is the only source. The Automotive Industry Overview might mention ZF in general, but it won’t give you the 24-pin connector part number. That’s on page 3.

Frequently Asked Questions

Does this parts catalog include wiring diagrams?

No. This is a parts catalog, not a service manual. It lists component part numbers, assembly groups, oil specs, and conservation details. Wiring diagrams are not included. For electrical diagnostics you need the ZF service manual for the 12 AS 3002 S.

Can I use this catalog to cross-reference parts from other ZF models?

Not directly. The material numbers are specific to this transmission variant. However, ZF often uses common seals and bearings across models. If you find a part number in this catalog, you can check other ZF parts catalogs for matching numbers. The Automotive Industry Overview may provide general background, but the part numbers only match within the same series.

Is the oil capacity in quarts or liters?

Liters. The catalog states 13 dm³, which is 13 liters or about 13.7 US quarts. Imperial quarts are 1.136 liters each, so 11.4 imperial quarts.

How do amendment numbers affect part ordering?

Amendment numbers indicate engineering changes applied to the base transmission. If your unit has amendment 001, you need parts that supersede the original design. The catalog lists amendment start dates (often 00.00.0000 meaning no start date). Always verify your transmission’s amendment level before ordering. Ignoring amendments can lead to mismatched seals or valve block revisions.

When you’re rebuilding a 12-speed ZF transmission, having the factory parts catalog on the bench saves you from ordering the wrong part and waiting a week for the correct one. Every material number, every oil spec, every assembly group – it’s all there. Access the Factory Manual now and keep it with your transmission documentation.
