Shudder at highway speed
A vibration at light throttle between about 25 and 55 mph, like rumble strips. Usually the torque converter, not anything deeper.
$1,200 – $2,800★★★★★ 5.0 from 177 reviews · Serving Southlake
European ZF service for Southlake, about 22 minutes up SH-114.
Southlake driveways have a lot of BMWs, Range Rovers, Jaguars and Audis, and many of them run ZF 6HP, 8HP or 9HP transmissions. We have the tooling, the ZF LifeGuard fluid and the temperature-controlled fill process these units need, which a lot of shops in the area do not.
1925 Golden Heights Rd, Suite 108. North Fort Worth, just off I-35W near the Alliance corridor.
Getting it to us
West on SH-114, then I-35W south. That is the whole trip, and you only make it if you want to. If the transmission is slipping, flaring or will not engage, leave it where it is and call. We send the truck.

For Southlake drivers
A harsh engagement, a clunk into reverse or a transmission fault on the dash of a BMW or Range Rover is often the mechatronic unit or its sleeve seal. Caught early, that repair runs $1,500 to $3,000. Driven on, it becomes a $3,500 to $7,000 rebuild.
ZF transmission service →We rebuild for all makes: Chevy, GMC, Ford, Ram, Dodge, Chrysler, Cadillac, Buick, Nissan, Honda, BMW, Range Rover, Jaguar, Audi and more. Automatics, manuals, transfer cases and clutches.
