mini cooper gearbox repair

Mini Cooper Gearbox Repair

A Mini Cooper gearbox repair was recently carried out by Ware automatic gearbox repair specialists at Stephens Engineering.

The 2003 Mini Cooper was brought into the workshop with a complaint that the Mini Cooper had a very noisy transmission and also, there was a delay in engaging the forward gears. The 2003 Mini Cooper has a C.V.T. which is a constantly variable transmission.

In our experience, the Mini Cooper CVT transmission works extremely hard and the bearings and drum are often found to wear considerably as a result of the drive belt tension. With the Mini Cooper CVT transmission unit, as it wears over time, the Mini gearbox requires careful inspection of all moving parts with the CVT transmission unit.  When we remove and dismantle the Mini Cooper automatic transmission, we often find that it is necessary to replace most of the  moving parts due to the work of this little unit.

Common problems with the Mini Cooper CVT transmission are wear and failure of the drums, the drive chain and all bearings within the Mini Cooper gearbox, as was the case with this 2003 Mini Cooper gearbox repair.

The Mini Cooper gearbox was refitted, after re-assembly and replacement of the worn drums, drive chain and bearings.

To ensure smooth running of the repaired Mini Cooper gearbox, it is crucial to set the vehicle adaptations to its control unit and finally a long road test allows the vehicle to finish its relearning procedure and confirmed that the Mini Cooper gearbox repair had been completed successfully and the vehicle was running smoothly again.

Volkswagen Polo gearbox repair

Hyundai Accent Gearbox Repair

A Hyundai Accent gearbox repair was carried out recently in the Stephens Engineering workshop.

The 2008 Hyundai Accent was brought in with the complaint that a warning light came after the Hyundai Accent had been driven for a few miles. The Hyundai Accent fault codes were checked in the workshop and the Hyundai Accent fault code stated that the problem was in the torque converter circuit.

This Hyundai Accent had recently been in to a main dealership for a fluid leak from the transmission and the converter and the pump seal it runs on were replaced .  The warning code only came on shortly after the repair carried out at the dealership.  The opinion of the dealership was that this 2008 Hyundai Accent needed a new transmission unit.

The Hyundai Accent was brought into our workshop for a second opinion and on the Hyundai owner’s instructions, we removed the Hyundai gearbox and then fully dismantled the Hyundai automatic gearbox for a full and detailed inspection of the transmission unit.  With a mileage of less than 40,000 miles, we were surprised this was necessary.

On inspection of the automatic transmission, we discovered there was not a great deal wrong with the main workings of the Hyundai Accent gearbox, however, inside the oil pump, the bush supporting the torque converter was missing and we could only assume that this was fused onto the old converter which had been replaced by the dealership.

The Hyundai Accent gearbox repair was carried out in the workshop and the oil pump assembly was replaced. In addition, we also replaced the Hyundai friction plates as they had suffered from lack of lubrication.  The Hyundai Accent transmission was then re-fitted in the Stephens Engineering workshop and the Hyundai Accent was subject to a long road test which confirmed that the fault had been rectified by the automatic transmission specialists at Stephens Engineering and the vehicle was running well without the need for a new gearbox.

Land Rover Discovery Gearbox Repair

Land Rover Discovery Gearbox Fault Repaired: a 2009 Land Rover Discovery gearbox repair was carried out in the Stephens Engineering workshop recently. The Land Rover Discovery was brought into the workshop with a complaint of a vibration throughout all the Land Rover Discovery gear changes when on a light throttle.  The Discovery had no fault codes recorded.

The 2009 Land Rover Discovery automatic gearbox is the Z.F 6hp26 automatic transmission. At fairly high mileage, the torque converter can slip and judder which produces a vibration during gear changes.

The Land Rover Discovery gearbox repair required the removal of the gearbox. The gearbox was removed and dismantled in the Stephens Engineering workshop and excessive wear was shown to have occurred to the main bushings and the drums were also scored. The Land Rover Discovery automatic transmission was overhauled which included the Discovery’s clutches and solenoids.

To clean the torque converter, it was cut open and the torque converter was placed in the ultrasonic cleaner.  Thorough examination of the automatic transmission unit showed that the lock up clutch plates were worn, as  were the sealing rings. The clutch plates and sealing rings were replaced, the torque converter was re-welded and then balanced and checked for leaks.

The lock up operation of the torque converter of the Z.F 6hp26 automatic transmission is critical and its pre-load is set on a special rig within the specialist machine workshop at Stephens Engineering. A modified sump assembly was also fitted prior to the Land Rover Discovery’s automatic transmission being refitted as the original sump assembly could not be removed for a filter change once it had been fitted back into the Discovery’s  chassis.

Running computer adaptions were carried out and the Land Rover Discovery gearbox repair was checked and the vehicle was taken on a long run. A final check for leaks was undertaken, the Land Rover Discovery gearbox repair had been successfully completed and ready for the customer.

Volkswagen Polo gearbox repair

Renault Gearbox Repair

The automatic transmissions specialists at Stephens Engineering, regularly carry out Renault gearbox repair within our workshop.

A common problem requiring a Renault gearbox repair that we often see with the Renault DPO gearbox, is a reported ‘slip and thump’. The ‘slip and thump’ is the result of the Renault gearbox ‘slipping’ out of gear and making a ‘thumping’ noise as the Renault gearbox re-engages.

In our extensive experience of repairing Renault DPO gearboxes, the cause of this common fault to the Renault gearbox is the result of the torque converter one-way clutch spinning in its housing. The torque converter one-way clutch helps to maintain smooth gear changing and early action can prevent a complete failure of the Renault’s automatic transmission unit.

A common indication that the torque converter one-way clutch is beginning to fail is a clicking sound from the transmission unit and if left without remedial action, this will progress further, with the gearbox slipping out of gear and then resulting in a complete failure of the gearbox with a total loss of gears.

At Stephens Engineering, we have a dedicated specialist machine shop and we carry out a Renault gearbox repair to the torque converter one-way clutch by pinning the torque converter one-way clutch with three silver steel rods which are robust and sturdy to withstand the pressures of the unit and will probably out last the car. In addition, we would recommend the automatic transmission is overhauled at this stage.

When your Renault gearbox needs specialist attention, bring your Renault to Stephens Engineering, we provide knowledgeable and thorough service to keep your Renault transmission running smoothly.

Mercedes Vito Gearbox Repair

In the Stephens Engineering workshop we have recently seen a number of Mercedes vans brought for gearbox repairs; we recently carried out a Mercedes Vito gearbox repair. As with the Mercedes Sprinter, the most common gearbox fault for the  Mercedes Vito vans is torque converter failure. There are warning signs from the Mercedes Vito van before severe damage occurs to the gearbox and if the problem is caught early and repairs carried out, usually the gearbox itself is unaffected.

The Mercedes Vito is popular hard working vehicle and failure of the torque converter is due to the hard work the automatic transmission undertakes. The Mercedes Vito gearbox problems start with the internal bearing begin breaking up as a result of work these transmissions get through. At Stephens Engineering, we have our own converter shop within our workshop and as a result, we are able to carry out modifications to the Mercedes Vito gearbox, to strengthen and repair the faults and also improve the lock-up operation.

The first warning symptoms of a potential Mercedes Vito gearbox repair being needed are a judder on a light throttle and judder or stalling when coming to a stop in the Mercedes Vito.
