Repairing a BMW ZF 6hp26 Transmission

Worn clutch disc on top left, worn bushing on the right.

Worn bushing causes wear in E piston

Piston seal deterioration.

When the 6hp26 is removed we always have to look for greenish leaks from crank seal and upper coolant passage. This one was leaking from the upper passage.

Mechatronics seal in the 6hp26 and 6hp19 will crack with age and miles and cause the trans to leak pressure. The common characteristic of this is when you shift into drive or reverse it immediately shifts itself back into park

These two pics show wear from mileage and improper service regimens.

This E Clutch was in a lower mileage 6hp26 that had been run low on fluid from a leak that was left unattended. If you service with us regularly, we catch these leaks early so you won't need expensive services like these, as early as shown in this case.

This is the same 6hp26 transmission with low mileage wear from unattended leaks.

The pan on the left is for non-stop/start transmissions. The stop/start transmissions, on the right have a reservoir that holds fluid and pressure and keeps fluid moving through the transmission when the vehicle stops.

Another view of a cracked mechatronics seal on the right. The pic above is the mechatronics/valve body and the seal is sandwiched between it and the transmission body, inside the pan.

The facility is very clean, their service is quick, and they call you when they say they will. Overall, had a great experience with their repair to my BMW.However, I got some quotes for future services that are significantly higher than some dealers quoted me for the same repairs so do your research. If you understand that they aren't the cheapest around, you will be satisfied with their customer service

If I could give them more stars I would, they went way above and beyond what I expected. I have a 2013 Audi S6 that had a transmission failure, They sourced a reman unit and found a good used 1. They contacted my warranty company , They warranty company took a week to get their inspector out to look at it, another week to get the work approved. By then the good used transmission was gone. So Trent and his team located another on, but determined it was not worth installing . Well it turns out I have a odd ball transmission , which became nearly impossible to locate another 1. For over a month they kept trying to find another 1 with no luck. The whole time Trent and his team kept me in the loop as to what is going on. I finally made the call to just get the reman unit from Audi. I picked up the car and was very impressed , as always Trent and his staff were very respectful explained any questions that I had. I get to the car it was very well cleaned no finger prints or marks that should not be there.I am very picky when it comes to other people working on my cars and Trent and his team are by far the best that I have ever dealt with. If you have a Audi or any other brand of car they work on I would highly recommend Lone Star Bavarian long before I would recommend taking it to the dealer.

I have been using Lone Star for several years now and I can't say enough good things about them. They have always gone above and beyond when it came to service, the staff is polite, the technicians know their stuff and the dogs are a bonus.

Great customer service. Extremely knowledgable. Willing to take time to explain all the details of the pre-purchase inspection we hired them to perform, which was great because we were purchasing the vehicle from far away. They instilled confidence in the results of the inspection.
