Odnowiona (testowana na drodze) skrzynia biegów TOYOTA / LEXUS U660F - przekładnia główna 70 x 17|47, korpus zaworów Gen2 (1 czujnik ciśnienia)

When we rebuild this U660F transmission, we don't just repair it; we engineer out the original factory flaws.
First, we permanently fix the notorious case wear issue. We completely TIG weld the damaged bearing bore with a high-strength, hardened aluminum alloy, then precision-mill it on a CNC machine back to factory specs. This upgrade locks the bearing perfectly in place so it will never spin or destroy the case again.

Because case failures usually chew up the internal gears, we completely replace the front aluminum planetary assembly to guarantee quiet, smooth power transfer. Inside, we install all-new friction and steel clutch plates, along with brand-new rubber hydraulic pistons. This restores 100% factory fluid pressure, meaning absolutely no slipping and crisp, instant gear engagement.
Finally, we completely overhaul the valve body, solenoids, and the torque converter. The result is a fully bulletproofed transmission that shifts flawlessly and is built to outlast the original

After the rebuild is complete, we professionally install the transmission back into the vehicle and perform a comprehensive road test. We drive the car under real-world conditions to ensure the computer adapts properly to the new internal parts. We monitor fluid temperatures, check for perfect sealing, and verify that every single gear shifts flawlessly under load. This strict final quality control guarantees that when you drive away, your car is 100% reliable and completely ready for the road."
