Perhaps, you’ve bought a used transmission from a junkyard that didn’t bother to drain the oil using the drain plug. They just punched a hole in the bottom of the pan, and now you’re looking for a replacement pan. Or, your pan is badly dented or scraped or has a gash in it from hitting something, while driving. Perhaps you damaged your pan while trying to get it off the transmission of an early-model Audi A8 Quattro. We empathize …
For those situations, we offer used transmission oil pans. They are almost impossible to find in pristine order so ours are banged up somewhat too, but we have straightened them out reasonably well and/or the hole punched therein has been brazed shut by a professional welder.
Our pans come with the drain plug, fill plug, fill plug gasket and four magnets but not the gasket. We recommend the original ZF gasket that you can get from the ZF distributor (nice people) in Connecticut. You know you have the ZF one if it’s green in color.
We also don’t include the filter. For that, we are referring you to the ZF distributor in Connecticut too. You know you have the ZF filter if it’s embossed with “FILTRAN” and “MADE IN GERMANY.”
We also don’t include the 26 Torx T-27 bolts that go around the pan rim. The ones on your car should still be fine, but if you have lost or stripped a few, let us know. Last time we checked the Audi dealer wanted more than $3 per bolt. We can do better.
When the engine isn’t running, then on these transmissions, the oil level is above the top of the pan, so a good-condition pan and gasket are vital to prevent leaks.
As to its structural internals, the ZF 5HP-24A had two main versions, an early version (used on the early D2 A8 Quattro 4.2 V8) and a late version (used on the C5 A6 Quattro 4.2 V8 and the later D2 A8 Quattro 4.2 V8). You know you have an early version if the valve body has five green solenoids; that is the most obvious visual cue.
The early transmission type has letter codes of “DPZ” or “DSM” or “DTE” — all for the Audi A8, production date through 12/98. The early transmissions came with an early version of the oil pan, part number 1058203019. As I understand the ZF distributor, the earlier oil pans are slightly deeper to accommodate the earlier-style transmission filter, which had a 1″-long funnel. You can order the pan from our D2A8parts.com website here, and pay with PayPal or a credit card (via PayPal).
The later transmission type uses the later version of the oil pan, part number 1058203026, which is not quite as deep as the earlier-style oil pan since it’s optimized for the later-style transmission filter, which had a 3/4″-long funnel. You can order the pan from our D2A8parts.com website here, or our C5A6 website here. Either way you can pay with PayPal or a credit card (via PayPal).
The earlier-style filter has been discontinued so now all the new ZF transmission filters for this transmission have a 3/4″-long funnel and so now going forward you could probably use either the early or the late-style oil pan interchangeably on either the early or the late-style of transmission. We have placed the early-style and late-style pans side by side and analyzed them, and the difference is indeed very subtle.
Even so, we do still differentiate as to how we stock and sell these, in case you want to keep everything on your car absolutely part-number correct.
