Two Problems Commonly Found With The 6HP19 Transmission
Posted by Regis on Monday, June 10th, 2013
The 6HP19 transmission is a 6 speed made by ZF Friedrichshafen AG. It is designed to be used in rear wheel drive cars. There is also a model 6HP19A that is designed for use in all-wheel drive cars. Care needs to be taken when swapping out the transmissions because there are two totally different gear ratios available for this transmission. One has a final gear ratio of 4.44 while the other is 3.73. All six gears are different between the two transmissions.
The 6HP19 was use in the Hyundai Genesis, and the BMX X3, E60 520i and the 450i. The 6HP19A was used exclusively by VW for the Audi S4 and the VW Phaeton. Let’s take a look at a couple of problems that are commonly found with this fairly complex and expensive transmission.
The ZF 6HP19 transmission
Symptom: Burnt up clutch packs. Problem: This is caused by failures in the valve body. At first you will most likely experience problems with second and third gear slipping. If you catch the problem early enough, you might get lucky by only having to replace the valve body and reprogram the computer. If the problem is left unaddressed, not only will you have to replace the valve body, you will also have to replace the entire transmission. There have been so many complaints about the VW version of this transmission that VW has taken the highly unusual step of extending the valve body warranty on these transmissions to 100,000 miles.
There have been many problems with the valve body reported
Symptom: Transmission is not going into certain gears. Problem: The 6HP19 is a fully electronic transmission. It has a total of seven electrical solenoids. That’s a lot of solenoids! These solenoids are susceptible to failure. To be honest, this is a common problem with almost all electrical transmissions.
The solenoids can be damaged from a voltage spike, high transmission temperatures, vibration or poor connections. The solenoids found in this transmission are nothing more than fancy electrical/mechanical magnets that are used to move valves in the valve body via a plunger and a spring. The solenoids consist of a coil of fine wire that when energized with 12 volts, creates a magnetic field. This magnetic field moves the plunger, which moves the valve in the valve body. A spring is used to return the plunger/valve combination back to its original location once the current is cut off to the solenoid.
There are seven solenoids in the 6HP19 transmission!
It is within the coil of wire that the solenoid suffers the most problems. The wire can break or internally short out. A quick test with a hand held ohm meter will let you know if the solenoid is working correctly.
Whether your transmission ends with a bang as loud as a t-shirt cannon or a whimper, like a lost kitten, it all means one thing: it’s going to be costly. If for some reason your 6HP19 fails, consider replacing it with a re-manufactured transmission over one that was simply rebuilt. A re-manufactured transmission will include alterations and upgrades to the transmission designed to fix common failure points, make the transmission more durable and last longer. A rebuilt transmission will not include these.
A re-manufactured transmission will also include a much better warranty: three years compared to an average 90 days for a rebuilt transmission. There is a reason for the big difference in warranties. The company that re-manufactures transmissions believes so strongly in their workmanship and quality of the parts used that they are almost positive you will never need to use their very generous warranty. The companies that rebuild transmissions, on the other hand, obviously don’t feel the same way.

glad you fixed the problem, im just gonna leave this for the next dude that has some issues like me....i have the same car, but now i wonder if i have the ZF6hp19 or the ZF6hp19A version....
