Every vehicle needs diagnosis before anyone can promise a repair path. These are the situations we help organize before you decide what to do next.
Tell us when it happens, whether reverse still works, and if warning lights are on. A scan and fluid check come before guessing at a rebuild.
Fluid condition, leak location, and driving distance matter. If the vehicle is slipping badly or overheating, towing may be the safer next step.
A failed solenoid, valve body, converter, or internal clutch problem can lead to very different repair paths. The goal is a clear diagnosis and written estimate.
A clean 7 Series is a $25,000 - 50,000 vehicle even when older. A $2,800 - 4,200 rebuild with 2-year / 24,000-mile warranty is often the right call.
ZF 6HP26 mechatronic replacement - $1,800 - 2,600 installed and programmed.
More torque, larger unit, but same ZF family. Labor is slightly higher due to vehicle size and engine complexity.
Some 7 Series models have a park pawl that doesn't fully engage, allowing the vehicle to roll out of Park. BMW has addressed this - we can verify if your VIN is affected.
Yes - the 760Li with the V12 uses the ZF 8HP75. Same transmission, slightly more complex installation.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
