![]() ![]() You can find some more information on the transmission and fluid through the following documents: Precluding the ability to test out alternate fluids. ![]() While a few of the distributors wereĬurious as well about the compatibility of various other fluids, ZF would not honor warranty issues without the Esso fluid, ZF distributors in the US hoping to find an inexpensive source for the fluid - unfortunately, the fluid is normally stockedĪs drums, and most would sell by the quart at relatively high prices ($15-$19 USD). Seems to VERY STRONGLY recommend that only a particular fluid be used, that is, Esso LT 71141. Of the ATF through normal VW parts sources, I'd hoped that a suitable aftermarket replacement could be found - however, ZF Incidentally, this transmission and some of its variants are also used in late modelīMWs, which may help expand the research base if you have a particular question regarding this system. The VW/Audi Tiptronic transmission is manufactured by ZF, model 5HP19FL (A4 '96-'02, A6 The period, some further research into the transmission turned up some of the following. However, the transmission operated perfectly, with the smooth shifts I'd appreciated when the car was first purchased. Unfortunately, the car was in an accident at 63k, ~6 months after the ATF service, at a total loss. Pan - however, a fluid level check some weeks later showed the transmission to be properly filled.Ĭonsidering the state of the fluid that was drained, a complete flush, filter change, and installation of a transmissionįluid cooler is slated for the near future.stay tuned. The other possibility is that fluid from the torque converter drained back into the transmission The main cause of this points to aįactory mistake - the factory overfilled the transmission by a full quart, and the car's been operating like this for the In total, I drainedģ.7 quarts of ATF and completely filled the transmission after the specified 2.7 quarts. In reality, about a quart of highly darkened fluid poured out of the transmission. With the transmission at ambient temperature (around 60☏ at the time), theoretically resulting in zero fluid flowing from During my fluid drain, I started by checking the existing fluid level Specification for a properly operating transmission. While VW makes a fuss about checking the fluid level between 95-113° F, there's a reasonable bit of allowance in this We should be worried about overfilling the tranny,Īs per the Hitchhiker's Guide to the Galaxy - Don't Panic. Issue of the "sealed" transmission pops up and ruins everyone's day. Miles should ensure a long life, with a proper filter change and fluid flush every now and then. For the most part, just changing the fluid every 30k But for the rest of us who enjoy keeping a multikilo buckĮxpenditure around for a while, keeping the transmission happy should be a top priority - diluting fluid which has broken downĭue to heat, removing wear-in metal particles from the pan magnets, etc. Sell/total a car before 100k miles, this may well be true. If a manual transmission does not have enough fluid, or the fluid has been contaminated, it is possible for the transmission to become noisy, the internal parts to wear out faster and eventually for the transmission to fail.Volkswagen and Audi consider the transmission to be filled for life - considering how many folks If an automatic transmission does not have enough fluid, or the fluid has been contaminated, it is possible for the transmission to start to slip and eventually fail. In manual transmission cars, there is a case that contains the transmission fluid.Ĭontrary to an automatic transmission, the fluid in a manual system is not directly involved in changing gears, because it is a mechanical system, whereas an automatic transmission is hydraulic. The fluid provides the power/force required to shift into different gears. In an automatic transmission car, the transmission system has an oil pan that contains the transmission fluid and fluid filter. An automatic transmission shifts the car into different gears depending on the speed that you are driving. The transmission transfers power from the engine to the wheels of the car. Transmission fluid helps cool and lubricate your vehicle’s transmission’s internal parts. What is the transmission fluid all about? ![]() 2014 Volkswagen Passat L4-2.0L Turbo Diesel ![]()
