A Week in the Stephens Engineering Workshop – Automatic Transmission Specialists
As you would expect from the automatic gearbox specialists at Stephens Engineering, it been all about automatic transmission faults last week. Here’s a brief snapshot of our week in the Stephen Engineering workshop repairing automatic transmissions with just a few of the vehicles we’ve repaired:
We’ve cured the erratic shift pattern for a BMW 740 series after diagnosing contamination in the transmission fluid.
Using our diagnostic scan, we found a fault with the Mercedes “C” class transmission control unit, after replacing the part and reprogramming, running well.
The 2005 Vauxhall Astra with a semi automatic gearbox came in with an “F” mode fault code and was non-starting. After diagnostics, an intermittent fault was found in the clutch actuator unit of the Vauxhall Astra. The Vauxhall Astra’s actuators were removed and cleaned and the vehicle is now running.
A 2006 Jaguar S Type had an intermittent fault which the scan showed possible solenoid problems in the valve body. Thorough testing revealed a solenoid problem plus a leak off in pressure in the valve body assembly. After fitting new components and sump filter unit, a ten mile road test confirmed all was well.
