Audi Q5 Gearbox Repair

A 2010 Audi Q5 gearbox repair was carried out recently by the team at automatic transmission specialists, in the Stephens Engineering workshop.

The Audi Q5 was brought into the workshop with a complaint from the customer that the gearbox changes were rough and had a judder. A full diagnostic scan was carried and the code for the clutch temperature was present which indicate a problem with either the dual clutch unit or with the transmission control assembly. Further diagnostics tests were carried out in the workshop which pointed to an issue within the Audi Q5 transmission control assembly. The Q5 transmission control assembly was removed and modified parts fitted the assembly. In addition, fresh fluid was pumped into the unit and all codes and adaptions were reset.

The Audi Q5 was then taken on a long road test to check that there was no judder and that the  Q5 gear changes were smooth. The road test confirmed that the Audi Q5 gearbox repair had been successful, with no judder on changing gear and the gear changes were smooth.

Automatic Transmission Repair Specialists – A Week in the Workshop

Automatic Transmission Repair Specialists – A Week in the Workshop

It’s been another busy and interesting week fault finding and repairing automatic gearboxes in the Stephens Engineering workshop. This week’s brief snapshot of a week in the Stephens Engineering workshop highlights just a few of the vehicles we have worked on with automatic transmission faults:

A 2009 Range Rover Vogue with a “slip and jerk” on a very light throttle when in traffic with no fault codes on the scan, however, we discovered the cause of the problem for the Range Rover Vogue, after dismantling the transmission, pressure leaks were found in the clutch drum. We repaired the automatic transmission and the vehicle is now running well.

A 2012 Nissan Qashqai with a whine through all the gear speeds was brought in to the workshop. On dismantling the automatic gearbox, we found the bearings on the main and input shafts had lost their case hardening, the oil cooler pipe had been leaking and a lack of lubrication may have caused the bearing failure.  The bearings and shaft were replaced and the transmission refitted and all was well.

A 2012 Ford Focus “B” Max 2012  came in with bad noise vibration going into third gear.  A diagnostic scan of the vehicle produced no fault codes, confirming this was a mechanical fault, not an electronics failure.  The gearbox was repaired and cleaned throughout and refitted with a new dual clutch unit and the transmission is now performing well.

A Vauxhall Omega was brought in, stuck in limp mode.  An oil sample was taken and it confirmed there water content in the transmission fluid, thorough examination revealed the breather pipe had split and allowed water ingress into the gearbox.  The complete gearbox and torque converter were fully overhauled and after replacing the damaged parts, everything was running correctly.

A 2005 Mini Cooper was bought in with a limp mode problem, this was a permanent fault which appeared to be in the wiring. This was stripped back and the faulty wire replaced.  A new filter and oil were installed and all faults were cured.
