I'm trying to locate the auto dipstick in a '94 Caravelle; the owner's manual quite clearly shows that it should be just to the passenger side of the bonnet catch, but it is nowhere to be seen. I'm guessing that they deleted the dipstick at some point, so how do I check and top up the auto tranny fluid? Anyone?

can you look underneath and see one leaving???

Have a look at the Auto sump. If there is a bolt in the bottom, you need to take that bolt out when the engine is running. If the ATF just dribbles out with the engine running, then the level is correct.

They have a tube up into the sump at the level they want for the fluid, so when you take the bolt out of the bottom, if the level is at the top of the tube inside the sump, it will just dribble out. If it needs filling up, there is a Black tube on the outside of the transmission at the front. It has a red locking cap on the top of the tube. Take that off, then you can take the seal cap off and top up the transmission until it just dribbles out the bottom tube.

Thanks guys, I actually worked it out while I was waiting for someone to reply. We've only had this van for a few weeks and it's needed doing since we got it. I used the correct fluid as specified in the manual. I'll get it in for a service soon and it can be someone else's problem!
