I would be pretty confident in saying your gearbox will have cooler. You should have a couple of hoses coming from the box, just follow and see where they go. It is a real pain trying to see the oil level on the new dipsticks. The older models used to have a blackened matt finish on the dipsticks but I suppose now it's all down to cost so a plain dipstick saves a few pence. As previously said just lay on some kitchen towel and you will see the level. Note the dipstick should be screwed in to test level. Normally I would just place it in position but just fill to minimum mark. You will be close enough.
