Our mechanics carried out electrical and pressure checks before the Porsche transmission was removed.  After removing the transmission unit, the Porsche gearbox was dismantled and all the transmission parts were thoroughly cleaned and inspected. Upon inspection of the dismantled transmission unit, it was discovered that problem was due to a failure of the oil pump and also the hub of the torque converter. The wear to the Porsche transmission was no unexpected due to the power from the engine and that this vehicle had covered over 190,000 miles.

The Ford Focus vehicle was recovered into the Stephens Engineering workshop with a reported problem of having reduced forward drive.  The Ford Focus is a popular car choice for families and this family car was badly missed by it’s owners.

The Ford Focus gearbox repair in the Stephens Engineering workshop started with the Focus gearbox being removed and then the gearbox was dismantled.

2013 Mercedes Sprinter Gearbox Repair

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.

Avoid expensive repair costs, does your Mercedes Vito judder on a light throttle or when coming to a stop? Could your Mercedes Vito’s torque converter be failing? Bring your Mercedes Vito to the automatic transmission specialists at Stephens Engineering in Ware. Book your vehicle in to the Stephens Engineering workshop for the specialist automatic transmission treatment.

Mercedes Sprinter Gearbox Repair

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

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.

Gearbox Repair – A Week in the Workshop

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.

Nissan Note Gearbox Repair

Nissan Note Gearbox Repair by Stephens Engineering

A 2006 Nissan Note gearbox repair has recently been carried by Stephens Engineering.

A 2006 Nissan Note was brought into the workshop with a gear slip in fourth gear. The Nissan Note fourth gear slip was the result of worn sealing rings within the clutch drum. The Nissan Note had covered more than 100,000 miles and the Nissan Note automatic transmission components were at the end of their useful life. The Nissan Note gearbox required a complete overhaul; the bushes and clutches were beyond repair. At Stephens Engineering, we are able to manufacture replacement bushes. The gearbox was overhauled and new bushes were fitted to the transmission unit. The worn out components were replaced. In addition, the torque converter and solenoids were replaced to the automatic transmission unit of the Nissan Note and the Nissan’s tolerances were put back to their original clearances.  At Stephens Engineering, we carry out a long road test to ensure that the fault had been resolved and then a leak check proved that the Nissan Note was performing well.

At Stephens Engineering, we have many years of experience in repairing automatic transmissions and the manufacture of replacement components. Contact Stephens Engineering to book your vehicle now.

Automatic Transmission Repairs – A week in the workshop

Automatic transmission repairs in Ware

As you’d expect from the automatic transmission experts in the Stephens Engineering workshop, it’s been another busy week and for us, it’s all about automatic transmission repairs. We’re sharing a small snapshot of some of the vehicles and their problems that we’ve seen this week.

2012 Vauxhall Insignia was brought in needing automatic transmission repairs. This Vauxhall Insignia  has a front wheel drive six speed automatic transmission and in the Vauxhall Insignia, this unit does seem to have issues after approximately seventy thousand miles. Harsh gear changes were noted and this Vauxhall was brought in just in time for us to repair and return to smooth running.

2011 Vauxhall Astra which had covered  32,000 miles was brought in with gear change problems and no reverse gear.  After a thorough diagnostic scan, solenoid codes were noted and on inspection, we found that the transmission unit had overheated and damaged the internal components. We carried out automatic transmission repairs, removing and dismantling the Astra’s transmission and fitting a replacement torque converter. After re-fitting the Vauxhall Astra automatic transmission, the vehicle was running well.

2008 BMW X5 with a z.f. six speed automatic transmission was brought in with a slip in both 5th and 6th gear, the diagnostic scan picked codes highlighting a problem with the E-clutch assembly. When the BMW X5 gearbox was removed and dismantled and the E-clutch was pressure tested to check for pressure loss. We replaced the E-clutch unit and rebuilt the transmission using the original z.f. components and after some thorough automatic transmission repairs, the gearbox was back to original performance.
