The automatic transmission experts in the Stephens Engineering workshop recently carried out a Mercedes B Class automatic transmission repair. At Stephens Engineering, we have over 40 years experience in working on and repairing automatic gearboxes and we can justifiably call ourselves automatic transmission repair specialists. We were approached by the owner of the Mercedes B Class after his local garage had diagnosed a fault with the Mercedes B class CVT automatic transmission. We were contacted by the customer when local garages were unable to carry out the Mercedes B Class automatic transmission repair. The B Class Mercedes was brought into the Stephens Engineering workshop and here is what our customer had to say after the Mercedes B Class automatic transmission repair was carried out by Stephens Engineering:
“My B class Mercedes had just completed fifty four thousand miles when it developed a fault with the CVT automatic transmission which was diagnosed by my local garage here in Devon as having a broken drive belt.
After numerous phone calls it seemed impossible to get this repair done in the West Country. Searching further afield I found Stephens Engineering in Ware who were very knowledgeable and couldn’t have been more helpful. They carried a perfect repair on the gearbox and kept me informed throughout the whole process. I cannot recommend Stephens engineering highly enough. A remarkable stroke of luck to have found them.”

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.

A common Renault DPO gearbox fault seen in the Stephens Engineering workshop is a problem with the pressure control sensors within the DPO automatic transmission unit. Most Renault automatic gearbox faults brought into the workshop are a result of a pressure control problem within the Renault transmission unit caused by either the solenoids or the valve body.
Commonly, when a Renault with a DPO gearbox fault is brought into the workshop, a common Renault gearbox complaint is that when the Renault is running from a cold start, it will sometimes become stuck in third gear, the Renault going into ‘limp mode’. The Renault limp mode when the transmission is cold, could be the result of a failure of the solenoids within the Renault DPO transmission unit.
At Stephens Engineers, with our years of automatic transmission repairs, we are able to carry out a full and detailed diagnostic to the Renault gearbox to locate the Renault DPO gearbox fault. Once we have carried out a diagnostic check and located the problem within the Renault automatic transmission, to rectify the gearbox fault, the Renault’s transmission sump is removed and we also remove the valve body and replace the worn or damaged components.
A repair to a Renault automatic transmission unit which has being going into limp mode and sticking in third gear, can usually can be completed in our specialist workshop one day. To ensure your Renault is running smoothly, before we release your vehicle, we carry out a final road test. We carry out the final road test on a cold transmission and check the control unit again for fault codes.
Is your Renault going into ‘limp mode’ and getting stuck in third gear? Bring your Renault to the automatic transmission specialists at Stephens Engineering, we have years of experience repairing Renault gearboxes. Contact the automatic transmission specialists in Ware and book your Renault in for our specialist attention.
Recently in the Stephens Engineering workshop a Mercedes Sprinter gearbox repair was carried out by the automatic transmission specialists at Stephens Engineering. One of the most common Mercedes Sprinter gearbox faults is failure of the Mercedes Sprinter torque converter within the vehicle’s automatic transmission unit. A Mercedes Sprinter gearbox repair is generally required as a result of the hard work and use undertaken by the Mercedes Sprinter van.
Due to the hard work the Mercedes Sprinter transmission is put through, the internal bearing of the Mercedes Sprinter automatic transmission start to break up. An early diagnostic of worn and breaking up internal bearing means a timely Mercedes Sprinter gearbox repair can be carried out. When repairs are undertaken to the Sprinter van’s gearbox during the early stages of the the internal bearing failure, the Mercedes Sprinter gearbox itself, is usually not affected.
The first signs to be aware of that a Mercedes Sprinter gearbox repair is needed are a judder on light throttle and judder or stalling on coming to a stop. You can prevent significant damage to your Mercedes Sprinter gearbox by being aware of the early warning symptoms that the Sprinter gearbox torque converter may be about to fail through damaged bearings and bring your Sprinter van to the Stephens Engineering workshop. At Stephens Engineering, we have our own specialist converter shop and we carry out modifications to strengthen these faults as well as improving the lock-up operation of the gearbox.

Jaguar XF Gearbox Repair by Stephens Engineering
A 2012 Jaguar XF gearbox repair was carried out by the automatic transmission specialists in the Stephens Engineering workshop. The customer reported that when the Jaguar XF was driving at high speed and the engine was hot, the vehicle would default and go into limp mode.
This particular 2012 Jaguar XF was a diesel engine with the ZF six speed automatic transmission (later models have the eight speed unit). The Jaguar XF was brought into the Stephens Engineering workshop and a full diagnostic scan was undertaken. The diagnostic scan revealed ratio codes of slippage in E-clutch assembly.
The Jaguar XF automatic transmission unit was then removed, together with the torque converter. On dismantling the Jaguar XF transmission unit, we found a crack in the E-clutch unit and in addition, the main bushings were not performing well and were letting fluid leak past their running shafts.
We carried out a full rebuild of the Jaguar’s automatic transmission unit and fitted a new drum assembly. The automatic transmission unit’s torque converter was rebuilt in-house by our team of specialists, using ZF parts. Finally, we changed the gearbox intercooler unit as these do tend to leak. The final road test confirmed that the Jaguar XF gearbox repair had been successful and the vehicle was now driving well and no longer defaulting to limp mode.
Is your vehicle defaulting to limp mode unexpectedly? If your vehicle isn’t performing as well as it should, book your vehicle in with automatic transmission specialists at Stephens Engineering and let us get you back motoring.
Audi A5 Gearbox Repair by Stephens Engineering
A 2009 Audi A5 gearbox repair was carried out in the Stephens Engineering workshop. The 2009 Audi A5 is fitted with a eight speed, front wheel drive automatic transmission. The Audi A5 was reported to be suffering from harsh gear changes and also, the gearbox warning light came on whilst driving on the motorway.
A full diagnostic scan was undertaken of the Audi A5 for trouble codes and once the trouble codes had been noted, the Audi A5 automatic transmission was removed and then dismantled in our workshop. The transmission unit checked thoroughly and the trouble codes investigated and actioned.
The Audi A5 automatic transmission is labour intensive unit, but very well made and with some TLC in the Stephens Engineering workshop, the Audi A5 transmission unit was ready to be refitted after only two days. The Audi A5 gearbox repair was completed once we had refitted the gearbox and cleared the trouble codes. The Audi A5 was given a long road test to confirm that the gear changes were no longer harsh and that motorway driving did not cause the gearbox warning light to come on. After the road test, the Audi A5 gearbox fault had been repaired.
Are you experiencing harsh gear changes when driving your vehicle, you need to book your vehicle in Stephens Engineering, the automatic transmission experts.
Stephens Engineering Bentley Gearbox Repair
The automatic transmission experts at Stephens Engineering carried out a Bentley gearbox repair recently. A 2009 Bentley was brought in the Stephens Engineering workshop with the complaint of a bad whine and also vibration when the Bentley accelerated. The 2009 Bentley is fitted with a four wheel drive transmission, with the six speed ZF transmission unit. The customer brought the 2009 Bentley in to ourselves and believed that the bad whine and vibration whilst the Bentley was under acceleration was due to a problem with the ZF transmission unit. With our years of experience and expertise in repairing automatic transmissions, we were not convinced that the fault did lie with the Bentley ZF transmission unit. Prior to potentially condemning the Bentley’s transmission unit, we carried out several checks and examinations of the Bentley’s transmission unit. After a thorough examination of the Bentley ZF transmission unit, we decided to change all of the Bentley’s gearbox and engine mountings, these were fitted and in addition, the gearbox fluid and the sump filter were also changed. The Bentley was then taken out for a road test to check whether the whine and vibration had been resolved; the road test confirmed that the ZF transmission was not the problem and that we had carried out the Bentley gearbox repair by changing the gearbox and engine mountings, without the need to condemn the ZF transmission unit.
At Stephens Engineering, we deal with all aspects of automatic transmission faults and we’re able to identify the cause quickly.
If your vehicle isn’t running as well as you feel it should, book your vehicle in with Stephens Engineering for our specialist knowledge and expertise.
Gearbox Repair – A Week in the Workshop
At Stephens Engineering, we’re known for our knowledge and expertise in fault finding and the carrying out of automatic gearbox repair. Our knowledge and experience gives us the edge; we have worked on most automatic transmission units and over the years, we have rectified a wide range of faults and problems.
We often see vehicles being brought into the Stephens Engineering workshop and our customers report a problem with the gearbox and more often than not, they’re right, however, there are occasions when a customer experiences problems with their car and believes it to be transmission related and our experience tells us that this possibly is not the case. With our automatic gearbox fault finding experience, we’re able to recognise faults that appear to be gearbox problems but are not the result of a gearbox fault. A good example of this scenario is the Bentley recently brought into the workshop with a transmission fault and a vehicle owner considering a new automatic transmission for their Bentley. Whilst there was certainly an issue with the performance of the Bentley, there was a particularly bad whine and vibration when the vehicle was under acceleration, our experience told us this was not a transmission issue. Examination of the transmission unit confirmed that the problem was, in fact, the gearbox and engine mounting.
Our customer could have been faced with an expensive repair bill to replace the complete transmission unit, however, with our knowledge and skill, we were able to find the true cause of the problem and get the vehicle back on the road quickly.
If you suspect your vehicle has a problem with it’s automatic transmission, book your car in to the Stephens Engineering workshop in Ware, the automatic transmission experts fault finding and repairing automatic transmissions for over 40 years.
BMW X5 Gearbox Repair by Stephens Engineering
A 2008 BMW X5 gearbox repair was recently carried out in the Stephens Engineering workshop. The 2008 BMW X5 has the ZF six speed automatic transmission. The earlier BMW X5 version used a GM five speed or the ZF five speed unit. The BMW X5 was subject to a road test which confirmed the problem was a slip in 5th and 6th gear of the BMW X5. The diagnostic scan noted the code “Slip from the E-clutch assembly”.
To commence the BMW X5 gearbox repair, the BMW X5 gearbox was removed and dismantled. The BMW’s E-clutch was then pressure tested whilst being subject to heat which confirmed the BMW E-clutch had a pressure loss. The E-clutch unit of the BMW X5 transmission was replaced with a ZF drum assembly and the transmission unit was then rebuilt using original ZF components. The valve body of the BMW X5 was up-rated and the automatic transmission was re-assembled. The automatic transmission unit was refitted with an exchange torque converter. The BMW X5 transmission control unit was adapted. To check that the fault had been successfully rectified, a long road test carried out and this confirmed that BMW X5 gearbox repair had been successful and that the gearbox of the 2008 BMW X5 was back to it’s original level of performance.
