Where do you check the automatic transmission fluid on a 2002 Isuzu Rodeo?

The Transmission fill plug on these models is located on the bottom of the pan. There are 2 plugs located there. One is the drain plug and the other is to fill/check. The fluid should be high enough to slowly trickle out of the hole. This has to be checked while the engine is running and in gear. This is VERY DANGEROUS process. It is advisable to have your local shop do this for you. I had to change the fluid in one about 6 months ago and was very disappointed in the design. I would recommend having the dealer do this for the reason that they are familiar with the concept of how it is done. Most shops will not be able to accomplish this with accurate results. Again, This is a very dangerous due to the vehicle having to be running and in gear before and reading can be obtained. If not runnin it will be over full.
