Automatic Gearbox Help!

[toughguy]

First post here haha so doubt anyone can help me but my 54 plate voyager does not accelerate properly and sometimes will not go into reverse gear. I brought the car from auction and it has always had this problem. Auction said I had 24 hours to report fault so guess I brought a piece of s*it

Have you had the error codes in the TCM read yet, you need to get this done.

No because my mechanic said he could not read the codes as it was not responding.

So the TCM is not responding. On the instrument panel where the gear selection symbols are (PD12RN) is each symbols in a 'square'? This square normally displays what position the selector lever is in but is in highlighting all the symbols?

Never noticed but just checked and yes they are why?

I suspect a supply wiring fault to the TCM or a faulty TCM which is not unknown.

 

First thing I would do is look behind the left front wheel arch plastic guard where the TCM is located, you might find it easier to remove the wheel first and look carefully at the TCM (silver box about 10" square bolted) for signs of damage or water corrosion.
