Hi guys, new to the forum, so go easy.
My van, a 2007 Mercedes Vito 122 cdi crew van with a 3.0 V6 diesel engine and a 722.6 auto box, which I believe, has recently developed a fault whereby as it slows down and you don’t apply the brakes, there is a noticeable/ loud squeaking or squealing noise, which appears to be coming from the gearbox. This only happens when you slow to a stop or are at low speeds. It also doesn’t happen, or is not noticeable at higher speeds, when you slow. If you slow down using the footbrake it also doesn't occur and when you apply the accelerator it stops. Further to that when you put it into reverse there is like a grinding noise, but only slight, more like a brushing noise. I believe it is the gearbox but it could be the driveshaft as the audible sound does appear to be more external than internal, plus there is no real feedback through the steering wheel, pedals or vehicle itself, just the noise.
The gearbox has always had a shudder when at low speed and you put your foot down, but I assumed that this could be due to the power of the engine.
I spoke with the mechanic we use (he does small jobs and gets it through the MOT) who suggested taking it to a gearbox specialist. I live close to Exeter, and was advised to use a nearby specialist, however after looking at reviews, they didn't instil me with confidence.
I'm asking if anyone on the forum recognises the symptoms I've described and also if there are any recommendations for Autobox specialists who can do the work.
Although I live in the South West, the van is drivable at the moment and I am prepared to travel to find a trustworthy specialist, although not hundreds of miles.
Thanks in advance guys
