In the Ware workshop of automatic transmission specialists, Stephens Engineering, a 2003 CLK Mercedes gearbox repair was recently undertaken.
The 2003 Mercedes CLK was brought into the Stephens Engineering workshop with a complaint that the Mercedes CLK had no drive when hot, with reports of a high pitched whine. The Mercedes CLK Class models are susceptible to suffering from water ingress and therefore, a glycol test was carried to ascertain whether water was present within the transmission unit of the Mercedes CLK. The glycol test confirmed the Mercedes CLK radiator had failed by letting glycol and water seep into the transmission unit. When a failure of this type occurs within the Mercedes CLK transmission, all of the components and the torque converter must be replaced.
To achieve the 2003 CLK Mercedes gearbox repair, a new radiator can be fitted to the vehicle. To prevent a re-occurrence of this type of Mercedes transmission failure, a retro separate cooler can be fitted. Prior to refitting the Mercedes CLK transmission, the circuit board was also changed and part of the valve body was updated.
The 2003 CLK Mercedes gearbox repair was tested with a ten mile run during which the 2003 Mercedes CLK now performed as new.
The Ware automatic gearbox specialists, Stephens Engineering, recently carried out 2006 Volvo XC90 gearbox repair.
The 2006 Volvo XC90 is a popular four wheel drive automatic and unlike the earlier XC90 vehicles, the 2006 Volvo XC90 has a six speed gearbox. Pre-2006 the Volvo XC90 had a 5 speed gearbox. The 2006 Volvo XC90 gearbox repair was needed as the 2006 XC90 had lost third gear and was slipping through the other forward gears. The Volvo XC90 was ready for a complete overhaul in the Stephens Engineering workshop as the Volvo had covered a hundred and ten thousand miles. The Volvo XC90 5 speed gearbox and the Volvo XC90 6 speed gearbox are both a very reliable automatic transmission unit.
To carry out the 2006 Volvo XC90 gearbox repair in the Stephens workshop, the Volvo transmission and transfer box was removed and the Volvo XC90 automatic gearbox was dismantled. All the components within the Volvo’s transmission unit were checked as a result of the vehicle’s mileage and all the clutches and sub-units were replaced. Both the 2006 Volvo XC90 and the earlier Volvo XC90 5 speed gearbox can suffer from leaks and solenoid failure and so a new valve body assembly was fitted to the 2006 XC90. When either Volvo XC90 model is brought into the workshop, we always fit a new valve body assembly to avoid further damage caused by leaks and failure of the solenoids. The Volvo XC90 gearboxes work very hard and therefore, the specialist automatic transmission technicians at Stephens Engineering want to ensure the gearbox problems are fully rectified prior to installation. Prior to the installation of the Volvo XC90 automatic gearbox, the Volvo gearbox oil cooler is hot flushed, for efficient and effective cleaning and finally, the Volvo XC90 torque converter was replaced.
Software updates for the 2006 XC90 were checked and to check the 2006 Volvo XC90 gearbox repair had been carried out successfully, the Volvo XC90 underwent a ten mile run with final checks which confirmed the XC90 gearbox repair had been successful and the Volvo automatic transmission was running well.
The Ware based automatic transmission specialists, Stephens Engineering, recently carried out a Chrysler Grand Voyager gearbox repair.
The Chrysler Grand Voyagers was brought into the workshop with complaints from the owner that the Chrysler was “rough” on the gearbox downshifts and a futher complaint that the Grand Voyager was “noisy” in all forward gears.
The Chrysler Grand Voyager was brought into the workshop and the vehicle was scanned for error codes using our state of the art diagnostic equipment. The Chrysler recorded no transmission fault codes during the scan. As a result, the Chrysler Grand Voyager transmission was removed and dismantled. On thorough examination in the Stephens Engineering workshop, it was obvious to the experienced automatic transmission specialists that the Chrysler gearbox had previously been overhauled before but crucially, several items had been missed during the earlier Chrysler gearbox overhaul. The examination of the dismantled Chrysler Grand Voyager gearbox revealed two important gearbox bearings were badly pitted and a gear set spline was 90% worn through.
The Chrysler Grand Voyager is a six speed automatic and tolerances are fairly critical. The Chrysler Grand Voyager transmission unit was thoroughly overhauled in the Stephens Engineering workshop and worn and pitted gearbox bearings were placed, as was the worn gear set spline. In addition to fitting the new gearbox parts, new clutches were also fitted and finally, new seals and solenoids were fitted to the Chrysler gearbox.
The Chrysler Grand Voyager transmission was re-installed and adaptions re-set and the Grand Voyager was subjected to a long road test proved all was well again and the Chrysler Grand Voyager gearbox repair had been been successful.

The automatic gearbox repair specialists at Stephens Engineering carried out a 2012 Nissan Micra gearbox repair in the workshop.
The 2012 Nissan Micra was brought into the Stephens Engineering workshop, the Nissan Micra had lost drive completely. The first thing to do before the 2012 Nissan Micra gearbox repair could be completed was for the transmission unit to be removed and dismantled. Inspection of the Nissan Micra transmission revealed that the inside of the Nissan Micra transmission was contaminated with a mixture of automatic fluid and antifreeze. The transmission contamination was traced to the gearbox oil cooler which in the Nissan Micra is located at the bottom of the radiator and when the transmission becomes hot, the solution turns to steam.
For a vehicle gearbox, this is the worst type of transmission contamination as it attacks the bonding of the friction plates in both the gearbox and also the torque converter. All the damaged and marked components were replaced, the friction plates and solenoids were marked and damaged and subsequently replaced. The Nissan Micra transmission was re-fitted, complete with a new radiator. To ensure all contaminants were removed from the transmission unit, all cooler pipes were flushed through with hot fluid.
The Nissan Micra four speed transmission is quite a strong transmission unit however the Micra gearbox function had been compromised by the water. The Nissan Micra underwent a long road test and all was well, confirming that the 2012 Nissan Micra gearbox repair had been successful. In addition, to ensure that the last traces of moisture had been removed, we confirmed to the customer that we would change the fluid after a thousand miles.

The automatic gearbox specialists, Stephens Engineering, recently carried out a 2013 Mercedes Sprinter gearbox repair.
The 2013 Mercedes Sprinter gearbox is a seven speed automatic gearbox. The Mercedes Sprinter vehicle are very popular and often the vehicle of choice for delivery companies. The Mercedes Sprinter van brought into the Stephens Engineering workshop had been used extensively by its supermarket owners and as a result, the vehicle’s mileage was quite high.
When the Mercedes Sprinter was brought into the Stephens Engineering workshop, the 2013 Mercedes Sprinter gearbox had little drive and also burnt transmission fluid. The Mercedes Sprinter gearbox was removed and dismantled in the Stephens Engineering specialist workshop. The Sprinter van’s main running gear and clutch drums are mainly aluminium construction and as a result, the aluminium gearbox components wear on any friction mated area.
In the Stephens Engineering workshop, the Mercedes Sprinter gearbox required a complete replacement of the gearbox drums and gear sets. With the Mercedes Sprinter, the electronic control plate and sensors are mounted on the transmission valve body and these components were also carefully inspected. To complete the 2013 Mercedes Sprinter gearbox repair, the Mercedes torque converter was also re-manufactured by the Stephens Engineering team, refitted and kept with its original transmission.
After re-fitting the Mercedes Sprinter torque converter and transmission, the gearbox adaption procedures were carried out together with clutch fill times, followed by a long road test to let all the new and repaired components settle in. The road test confirmed that the 2013 Mercedes Sprinter gearbox repair was successful.

Lexus G S 300 Gearbox
A 2005 Lexus G S 300 was brought into the Stephens Engineering Automatics workshop needing an automatic gearbox repair. The Lexus had a judder during gear change when hot. The Lexus G S 300 gearbox is a six speed, rear wheel drive transmission. The gearbox was fully inspected in the Stephens Engineering workshop and the gearbox pressure was found to be low and the transmission fluid has started to discolour. The vehicle had covered over a hundred and thirty thousand miles and was in need of some serious TLC.
The automatic transmission was removed from the Lexus, dismantled and then pressure washed. All the clutches were replaced with seals and gaskets and the solenoids were checked, tested and then changed. To complete the TLC from the experts at Stephens Engineering, all the drums were pressure tested and bushes renewed. The Lexus G S 300 gearbox was then refitted, together with a rebuilt torque converter.
The Lexus was taken out for a long road test to check that it was running well, on the road test, no faults were noted and all was back to normal and the Lexus was running well.

Volkswagen Passat DSG
A 2008 Volkswagen Passat with a DSG, “direct sequential gearbox” was brought into the Stephens Engineering Automatics workshop for automatic transmission repair. The customer had noticed when driving the vehicle that there was a whine and an intermittent loss of top and reverse gears when driving the Passat. The automatic transmission was removed in the workshop, then dismantled and inspected to uncover the automatic gearbox fault. On inspection, we found that the dual clutch was badly worn. The vehicle had covered over a hundred thousand miles and so, the amount of wear to the dual clutch was to be expected. Our thorough and rigorous inspection of the Passat DSG transmission unit found that the main shaft bearings had also worn. The Passat’s DSG transmission was completely cleaned in the workshop and the worn main shaft bearing were replaced. The Volkwagen Passat DSG transmission was refitted and a new dual clutch was fitted. After resetting the adaptations, the vehicle was taken for a long road test to check that the whine was no longer present and that there was no loss of top and reverse gears. The long road test confirmed that the vehicle was running well and that everything was back to normal.

Ford Galaxy Powershift
A 2001 Ford Galaxy powershift was bought into the Stephens Engineering workshop. The Ford Galaxy powershift has a six speed dual clutch front wheel drive transmission which combines the positives of both manual and automatic transmissions. The Ford Galaxy are extremely popular and we see a number of vehicles used for taxiing and these vehicles usually come into the Stephens Engineering workshop with high usage and mileage.
The fault report for this vehicle was that it had lost all drive and had the fault code for restricted performance. In the workshop, the Ford Galaxy’s gearbox was removed and dismantled. On examination, we noted that the clutch assembly was worn and that particles had contaminated the transmission unit. All components of the automatic transmission were thoroughly cleaned and inspected, the filters were changed and the cooler lines were hot flushed to ensure they were free of contamination. The transmission was refitted to the vehicle, complete with a new dual clutch assembly.
At Stephens Engineering, we carry out a long road test to text and check that the vehicle runs well and without any issues. The long road test was carried out and the vehicle rechecked for leaks and was noted to be running well.
High mileage, especially for vehicles like the Ford Galaxy, doesn’t have to be a problem. At Stephens Engineering we are experts in automatic transmission fault finding and automatic transmission repair.

Mini Cooper Intermittent Limp Mode
A 2005 Mini Cooper was brought into the Stephens Engineering workshop with an intermittent limp mode problem. The fault was intermittent and only apparent when the Mini Cooper was pulling away from rest or going around a roundabout. This problem, whilst intermittent, was the result of a permanent fault which appeared to be within the wiring of the automatic transmission. In the workshop, the sump was removed from the Mini Cooper automatic transmission and continuity checks were carried out between the transmission control unit and the solenoid on the valve body inside the Mini’s automatic gearbox. It was suspected that there was one wire going to ground somewhere within the vehicle’s loom. The Mini’s automatic transmission was stripped back and the faulty wire was located and replaced. We also installed a new filter and replaced the oil. Only then did we carry out a full road test which confirmed all the faults were cured.
At Stephens Engineering we have over 40 years of automatic transmission fault finding, with our vast knowledge of automatic gearbox faults, we can locate the problem, even when the issue is an intermittent fault.
If your vehicle has an intermittent fault, why not book in with Stephens Engineering and let us get to fault cause and rectify it for you.
Vauxhall Omega in Limp Mode
A Vauxhall Omega was brought in to the Stephens Engineering workshop stuck in limp mode. A full diagnostic scan was carried out in the workshop and the report was speed sensor fault. An oil sample was taken because of our wealth of a fault finding experience with previous known faults. Testing the oil sample we were able to confirm that there was some water content in the transmission fluid. The radiator is the usual culprit for water contaminating the transmission fluid, however, we carried out a further examination and found that the breather pipe had split and that this had allowed water to ingress the Vauxhall Omega gearbox. The water contamination of the automatic transmission required a complete and thorough overhaul of the automatic gearbox and torque converter. We also checked the speed sensors and solenoids and these too had been damaged by the water and both the speed sensor and solenoids were replaced. To ensure that a vehicle is running well and that the fault has been fully resolved, we always carry out a long road test.
If your Vauxhall Omega has a fault with it’s automatic transmission or is stuck in limp mode, contact Stephens Engineering to book in your vehicle to our specialist workshop.
