Judder and hesitation when changing gear on automatic gearbox, suspect fault due to contamination build-up.
The fault was cured by draining and replacing the automatic transmission fluid, adding Forté Automatic Transmission Treatment and carrying out an extended road test.
Thanks to Autocare Wrekenton in Gateshead, Tyne and Wear.
Forté's Technical Helpline receives over 300 calls per month. This blog shares solutions for garage workshops on common driveability concerns that can be quickly and effectively treated. The vast majority of those identified are caused by fuel and oil borne contamination formed by natural degradation or via the combustion process. This is a fact of life for internal combustion engines where fossil fuels and oils are used.

Problem with a MAZDA 6 2.0d 2008 155k
Lack of power due to engine running in limp mode and diesel particulate filter (DPF) warning light on.
Fault code stored for DPF blockage, unable to carry out regeneration of DPF due to soot loading.
The fault was cured by removing the DPF to manually clean using 2 x Forté DPF Off-Car Cleaner as per instructions, carrying out an extended Forté New Generation Engine Flush and adding Forté Diesel Specialist Injector Cleaner and Forté DPF Cleaner and Regenerator into the fuel tank.
The DPF was then regenerated and reset using diagnostic equipment and taken on an extended road test with the vehicle power and performance restored.
