ZF 5HP19FLA Parts Catalog – What You Actually Get

If you are rebuilding a ZF 5HP19FLA and trying to match parts from a worn-out clutch pack or a leaking oil sump, you know the headache of aftermarket cross-reference sheets. They lie. I have seen more valve body assemblies ruined because some third-party list said “interchange” for a solenoid that was 0.2 mm too long. That is why you need the actual ZF 5HP19FLA Parts Catalog from the factory – 62 pages of OEM exploded views, part numbers, and torque specs that keep your rebuild from turning into a paperweight.

This is a parts catalog, not a repair manual. It does not tell you how to rebuild the transmission step-by-step, but it does tell you exactly which snap ring goes on which shaft and what torque to tighten the converter housing bolts. The ZF engineers who designed the 5HP19FLA wrote this. No guessing. No “equivalent” parts that don’t fit. If you are a home garage guy who likes to buy parts online and cross your fingers, stop. Buy this catalog first.

Transmission Oil Filling Procedures – Don’t Skip the Fluid Specs

Page 4 of the catalog covers the 5HP19FLA General Transmission Oil Filling Procedure. It lists the exact oil type and capacity for your specific application. Overfill it by half a quart and you get foaming, shift flare, and a fried torque converter. Underfill it? Same result. The catalog also includes the differential oil filling procedure (page 6) and transfer case procedure (page 7). You get the ZF-recommended lubricant reference chart on page 3 – cross-referenced against the OE part numbers. I have watched guys pour in Dexron VI because a parts store said “it fits.” That is a $4,000 mistake. Use the catalog.

Torque, Gear Ratio & Weight – Page 3 Is Your Baseline

Torque values in a transmission are not optional. The valve body bolts, the bell housing bolts, the pump cover bolts – each one has a specific torque in lb-ft from ZF. Page 3 of this catalog lists the torque specs for the 5HP19FLA, along with gear ratios and weight. Do you know the difference between the input shaft nut torque on a 5HP19 vs a 5HP19FLA? It is not the same. This catalog has the number. I keep a copy of page 3 tacked to my toolbox because I rebuild these units for Audi A4s and A6s. If you are a DIY mechanic doing your first rebuild, write that torque down twice. Cross-check it.

Inside the 62-Page Catalog – Key Groups from Gearbox to Valve Body

The catalog is organized by functional groups. You get the Gearbox Housing Group (page 9), Oil Sump Group (page 12), Converter Group (page 15), Planetary Drive Groups (page 16), Front Axle Differential (page 18), Rear Axle Output (page 21), Front Axle Output (page 23), Internal Differential Lock (page 24), Clutch Pack Groups (page 25), Valve Body Duct Plate Group (page 31), and Valve Housing Groups (page 35). Every group includes an exploded-view diagram with ZF part numbers. No GM or generic numbers. If you need a specific separator plate for the 5HP19FLA, you find it under Valve Body Duct Plate Group. Period.

For shops that specialize in German transmissions, this catalog is your parts bible. You do not order a “transmission rebuild kit” from a warehouse – you order the exact clutch pack C-group from page 25 and the exact seal kit from the Oil Supply Group (page 13). The catalog tells you which kit contains which parts; the 5HP19FLA Kit Content section starts on page 53. That is where you cross-reference your ZF part number against the kit number.

Selective Shims and Snap Rings – Why Page 46 Is Critical

Shim selection in the 5HP19FLA determines end play on the planetary sets. Too much play and the clutches slip; too little and the bearings bind. Page 46 lists all Selective Shims & Snap Rings with ZF thickness codes and dimensions in millimeters. You measure your clearance with a dial indicator, then look up the correct shim part number from this page. I have used this to fix a 2005 Audi A4 that had a harsh 3-2 downshift – the intermediate shaft snap ring was wrong thickness. The catalog saved a full teardown. Don’t guess shims. Page 46 is the only place ZF publishes the OEM stack-up chart.

Who Needs This Parts Catalog?

If you are a home garage enthusiast rebuilding a 5HP19FLA from a salvage Audi, you need this. If you are a professional tech who gets paid flat rate, you need this because the five minutes you spend looking up the correct part number saves three hours of returns. If you own a shop that services German automatics, buy this and also grab the ZF 16S151 ECOSPLIT III & 16S151 R 2007 Parts Catalog for the heavy-duty side of the business. And while you’re at it, the ZF 16S221 ECOSPLIT III 1316 2007 Parts Catalog OEM Specs and ZF 16 S 2521 TO 2010 Parts Catalog – OEM Factory Specs cover ZF manual transmissions – same factory documentation quality.

Source Validity – ZF Factory Documentation vs. Aftermarket

Aftermarket parts catalogs transcribe ZF part numbers from bad photocopies and half the time swap digits. This is a direct scan of the official ZF Industries, Inc. publication from 2003 (copyright page 2). The torque specs on page 3 come from the ZF engineering department, not from a forum post. The oil reference guide on page 3 is the same chart used by ZF service centers. I do not trust any other source for 5HP19FLA parts. If you want to understand the broader context of Automotive Industry Overview, that’s separate. For batteries in your transmission test bench, see Automotive Battery. But for the transmission itself, use the factory catalog.

Frequently Asked Questions

Does this catalog include torque converter specifications?

Yes. The Converter Group on page 15 has the ZF part numbers for the torque converter and the pump drive hub. Torque values for the converter-to-flexplate bolts are listed in the technical data on page 3, not in the group diagrams. You need both sections.

Can I use this catalog for a 5HP19 (non-FLA) transmission?

Only if you want to break parts. The 5HP19FLA has different gear ratios (page 3), different clutch packs (page 25, note the FLA-specific clutch count), and different snap rings (page 46). The non-FLA 5HP19 uses different shim stacks. Do not interchange parts between versions.

Stop tracking down parts using forum screenshots that are 72 dpi and missing half the number. Get the real document. Access the Factory Manual from AutoRepairManuals and keep it on your phone or print the pages you need. Your rebuild will go faster and the transmission will stay together.
