there is no drain plug for the transmission!
My transmission guy informed me that Nissan Pathfinders do not have a drain plug, that they are a self-contained unit. If you are leaking fluid, your seals need to be replaced

You can use any kind of SAE certified automatic transmission fluid in your 1993 Nissan Pathfinder. You can check the automatic transmission fluid level with the transmission dipstick.
If your 93 Nissan Pathfinder transmission won't shift into overdrive, check the transmission fluid levels. Ensure the fluid is at the proper level.
check the trans fluid
Remove the transmission plug on the bottom of the transmission. The transmission fluid will drain out of the unplugged whole.
5 & 1/4 Quarts with filter change.
Only use what is specified in the user's manual. For manual, use Nissan Matic D; for automatic, use Nissan Automatic Transmission fluid. Dextron is also an okay choice per the manual.
You drain and refill at the transmission from underneath the vehicle.
This vehicle do not have a transmission filter. All you have to do is drain the trans. fluid and refill.
It might be low on transmission fluid. If it's a 1995 automatic, many of them were defective and needed to be replaced.
To replace the transmission fluid in a 1993 Nissan Sentra, start by warming up the engine to thin the fluid, then turn it off. Lift the vehicle and locate the transmission drain plug, typically on the bottom of the transmission pan, and drain the old fluid into a suitable container. After draining, replace the drain plug, and then remove the transmission fluid fill plug (usually on the side of the transmission) and pour in the new transmission fluid using a funnel until it reaches the proper level. Finally, run the engine for a few minutes, check the fluid level again, and add more if necessary.
