Hi Marc,
Just as a quick update on this, I had it pulled out of the mud and managed to have a drive about in it and lift a few heavy things. I noticed that is seems to be very slow to start moving in reverse and on first start was worse - it needed alot of revs to get it moving. After say 5 mins or so of running about it seemed to respond much quicker and acceleration improved.
What worries me is with a decent sized load (around 300kg) and an incline the truck seemed to struggle a little going up the hill. Ive a load of heavy pallets coming in March that will come in around 1000kg or more and Im fretting that although it will lift them easily I may not be able to get them up the hill into our area.

Does this seem like it could be low transmission fluid level (im hoping) as I check the level when engine was cold and Ive since found it should be checked when running. Also because it improved with running I hoping more fluid got to the torque converter....

Additionally the lubrication chart on the truck seems to suggest that the torque converter oil is a different than the transmission oil - if that is the case then I cant see where to check/fill torque oil.

Try not to give me bad news ;)

Thanks in advance
Ben
