They are not maintainable and wear out almost uniformly, so replacing them all at once is the most reliable repair option. The solenoids in the ZF 6HP are practically a consumable if the mileage exceeds 150 thousand km. We took the parts of the valve body to the sink and in the meantime, we proceed to check the solenoids. On the left - the accumulator with maximum wear, in the center - removed from the repaired valve body, on the right - a new one In the photo below - the hydraulic accumulators of the valve body, no doubt, should be replaced with each repair. In this case, it is in normal state, but metal dust is clearly visible in the oil This is a separator plate, it works as a gasket sealing for a hydraulic plate - it is replaced if the rubber tracks are destroyed and cease to fulfill their functions. We remove the electronic board with the selector position sensor, remove the solenoids and disassemle the valve body itself. Reaming of one hole - 20$, plunger - 10-20$.Īssembly (necessary seals are changed free of charge) and final inspectionĭisassembling. Hydraulic plate channels reaming and installation of oversized valves. Solenoid testing on the stand +solenoid kit replacement This is how repair cost calculation looks likeĭiagnostics (disassembly, washing, vacuum testing, visual inspection and check plungers for jamming) It is modular, that is, we do not have a fixed repair cost, the cost is calculated based on the number of work performed and consumables used to repair. After, the 2nd generation of valve bodies appeared in which some design flaws were corrected, but they did not become really reliable.Īggressive driving style and an insufficiently frequent oil change lead to the appearance of symptoms such as blows and slippage when switching, in advanced cases - lead to damage to the mechanical part of the transmission and the car completely refuses to drive.īased on many years of experience in automatic transmission repair, Maktrans engineers learned how to restore the ZF 6HP mechatronics and give them a second life, now we will tell you how this happens and how much it costs. The first-generation valve bodies possessed an extremely modest working resource and "died" already at 100-150 tkm. Like all first-generation 6-speed gearboxes, the ZF 6HP has several vulnerabilities, one of them is a valve body, it is also a mechatronic. For the first time it began to be installed in 2000 on luxury models Audi and BMW with engines up to 6 liters. ZF 6HP - a series of 6-speed automatic transmissions manufactured by ZF. Opening hours for New Year holidays 2023.
