hello
Hi i also have a mistral - great truck once i learnt how to drive it.
Briggie is spot on they are a bit strange to drive until u get used to them.
if you look onthe top of the dashboard there is a flap - under that is either a large cross head screw or bolt - nip that up and the dash will vibrate less, for some reason i have to do it every now and then.
Check your fluids as you said if all ok see below
for the gearbox make sure the thermostat is ok as the top overdrive gear only comes in when the box is at working temperature.
if in doubt - if you look at the top of the thermostat housing there should be two plugs, on mine the nearest plug to the rad is the heat sensor to the gear box, it work as an earth if you "short" the plug ( put a short piece of wire between the two connectors) the gear box should go into top gear cold. that way at least you know that it exists and that a sensor or thermostat could be the problem. just a test though i would not drive it like it even though the auto gearbox place i went to reckons in our reasonably mild climate it would not do any damage.
oh and if the first plug u try has no effect try the other one as there is apparently no rhyme or reason as to which one is which.
Also these boxes are a bit jerky when cold as Briggie says just ease of the loud pedal
good luck with MOT.
