Right I have checked all fluids in the gearbox and all seems to be ok, not low, no grit etc. Still having the same problem when towing, it seems to stick in 3rd gear after about an hour of travel, only towing a single wheeled caravan . I have to pull over wait about 30 minutes or so to cool down then its ok again until i tow again for an hour or so. Any ideas what could be causing this anyone, need to get this sorted because towing to the isle of wight in a couple of weeks.

I take it this is an auto box, maybe it needs a fluid and filter change.

the filter is inside the sump a steel pan with wire gauze it can be cleaned there are also magnets to collect any steel debris these need to be cleaned aswell

its the colour of the oil that counts pink or light brown OK
if its any darker it needs changing

does the transmission oil temp light come on

is the oil going to the cooler in the bottom of the radiator

and just a thought do the brakes bind on caravan
if it does it again just check to see if the caravan wheels are hot
if they are over adjusted they may be free when cold but heat up and bind after travelling

No light comes on at all, just stuck in 3rd gear. I have had the caravan brakes off cleaned/checked etc, they are ok. How would i know if the oil was going through radiator?

I was checking all fluids last night, what is the container to the right of the radiator for, there is a pipe of the top of the rad into it and some fluid in the bottom.

right as you look at it from the drivers seat or right looking at it from the front (i.e. drivers or passenger side) Drivers side on mine has the radiator reservoir.
