About The 6DCT450 MPS6 Gearbox
This software module allows you to read, write and clone ECUs of 6DCT450 gearboxes that are used on Ford, Volvo and JLR cars. PowerShift TCM (6DCT450) PowerShift 6DCT450 Boot (MICRO) PowerShift 6DCT450 Boot (EEPROM) Supported: Reading, Writing, Cloning. 6dct450 oil is a high-performance synthetic fluid developed for the lubrication of dual clutch transmissions: DSG, DCT, DKG, PDK, DCS, EDC, DC4, GR6, PowerShift, STronic. Suitable for wet type DTCs. It has anti-wear, anti-vibration, anti-corrosion, and antifoam properties, allowing to reduce fuel consumption. 6dct450 oil: main characteristics.
The 6DCT450 MPS6 gearbox is a dual clutch semi automatic design, meaning that it features 2 different clutch packs that are controlled by the TCM 'transmission computer module' in order to achieve a smooth functional drive at all times regardless of road conditions.

However these gearboxes are prone to problems that normally start occurring at around 100K onwards, below is an outline of some common faults and problems these gearboxes encounter.Clutch Issues
Typical worn clutch symptoms include juddering & possibly slipping on pull away from a standstill. The causes of this is normally down to the clutch plastics & springs breaking into small pieces within the clutch housing. These plastic clutch guides & springs will need to be replaced normally along with the steel spacer rings and clutch friction rings. Clutch Plastic Breakage
As a result of the clutch guide plastics breaking up into small pieces, these can also make their way into the main gearbox. As this is a very precise gearbox and features many hydraulic channels you can experience problems relating to any part or component of the gearbox (not only a clutch fault) resulting from the build up of tiny parts of broken plastic clutch guides inhibiting key functions of the gearbox. Blocked Filters
The 6DCT450 MPS6 feature 2 filters in their design. The first filter is situated on the outside of the gearbox near the valve body. The 2nd filter is located inside the main gearbox. Both filters can become blocked and cause issues with this gearbox, both these filters will need to be replaced for an effective rebuild of these transmissions. Fork Piston Wear Appify web scraper free.
The 6DCT450 MPS6 uses a number of small black pistons made from a tough plastic material, however being that these pistons are in use 100's of times during every drive cycle, these can start to wear resulting in faults occurring that can include shift problems that will inevitably throw the gearbox into fault mode or limited transmission function. Solenoid Faults
(Be careful with these faults otherwise you will disappear down a rabbit hole and won't re-emerge very quickly) Solenoids on these gearboxes can fail from the magnetic core wearing out or contamination from miles upon miles of use, HOWEVER you can also get solenoid faults showing when all solenoids are absolutely fine and in working order, the faults are showing due to other component wear within the gearbox. Summary Get anydesk for mac os.
I really should emphasize that there is unfortunately no short cut when fixing these gearboxes and faults read with an OBD scanner may not show you the cause of the problem, only the result if that makes sense etc. For instance I have personally seen these gearboxes with only solenoid fault codes however the solenoids have all been working correctly, the actual cause of the fault was worn components elsewhere within the gearbox. If faults have started to occur then it is to late just to change the external filter and replace the hydraulic gear oil, the gearbox will need completely stripping down. From all our experience with this gearbox and it's faults we decided to create an OEM quality repair kit for these gearboxes that contains most if not all of the components you will need when rebuilding the main powershift gearbox unit. This rebuild kit can be found HERE
TCU's can also fail on these gearboxes however 90% of the time they tend to be in good working order with faults being caused from worn components etc.
