BMW Company Recent History

BMW has an outsized reputation for being on the cutting edge of technology in the automotive field. This was garnered from their “New Class” of cars that were released in the 1970s and continued through the 1980s. Since 2002, BMW has focussed less on keeping value in the car from sturdy construction and reliability. As more expensive technology has taken over the design process, in addition to becoming more integrated into the systems of the vehicle; BMW has lowered their emphasis on long-term reliability and so all current BMW drivers have a harder, more expensive experience owning these vehicles. We can help you trust your Bimmer’s reliability by keeping tabs on all of your BMWs systems every time you come in for service.

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.

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.

I've used Lone Star Bavarian various times. Awesome costumer service and a real honest group of guys...even when the news is not good. They always take care of me and do a great job. Better then the dealer ship.

I would highly recommend Lone Star! My Mercedes had a complicated problem that was not typical. Trent and his team researched and went above and beyond to fix the issue. He kept me informed along the way and took time to explain the issue in great detail. Everyone at the shop was very friendly and honestly, my car drives better than it ever has! Trustworthy for sure!

I took my BMW 550i to Mr. Cole after taking it to a few other places. Not only did the man fix the problem he even gave me a ride home!! I would definitely be using him again. I just bought a 335i and guess where I will be dropping it off at?? You guessed right!

Best in Fort Worth. I've been taking various BMWs to Trent and his guys since 2003 or so. Very knowledgeable and honest and fairly priced. Let's be honest, these aren't cheap cars to buy, or own, and that means repairs aren't the same price as a Honda, but you're not driving a Honda! Highly recommended!

Been using Lone Star exclusively since my warranty at the dealer expired on my 2005 BMW 525 back in 2011. Always helpful, accurate and consistent in how they treat customers. Will continue using Trent and his team until this BMW moves on to the next plain.

Trent & his crew have been steadfast in investigating a constant issue with my 2010 Mini Cooper. Until recently there were not “codes” whenever the car died in transit. No matter when or where, they would take the car and have a loaner for me so they could check the engine. They were able to pinpoint the issue and repair it... I cannot say enough good things about this shop, their focus on repairing an issue and their constant customer service.
