In a 1995 Nissan 240SX, the dipstick for checking the automatic Transmission Fluid is located near the back of the engine bay, typically on the passenger side. It is usually marked with a yellow or red handle. To check the fluid level, the engine should be running and the transmission in park or neutral. Be sure to wipe the dipstick clean before reinserting it to get an accurate reading.
No because the driveshaft and transmission are diffent sizes.
It should be on the right hand side towards the front
Nissan J-Matic Dexron 3 is also specified
YES!
For a 1991 Nissan 240SX, you typically need to use Dexron III/Mercon automatic transmission fluid for the automatic transmission. If you have a manual transmission, it's recommended to use a high-quality gear oil, such as 75W-90 or 80W-90, depending on the specific requirements. Always consult your owner's manual for the most accurate specifications and recommendations.

Yup, the bell housings are exactly the same.
how the transmission module works
only if the Nissan truck has the same motor. which some do by the way. some Nissan trucks have the same rear-wheel motor, KA24DE, or KA24E. if the truck has an automatic KA motor, then yes the transmission will fit right in. chances are the transmission mounts will line up, but if not you will have to remount it, which is just a matter of extending the mount and drilling a new screw-hole for the bolts.
You drain and refill at the transmission from underneath the vehicle.
No, the only models that came with a trans oil cooler built into the radiator where the automatic ones.
I have researched this because I am considering making the conversion from automatic to manual transmission on my own 1995 240sx. It involves buying a manual transmission used from a junk yard or a rebuilt one, the clutch parts, a manual shifter, and the pedal with associated parts. there are actually lots of good resources to show you the specifics on how to do the work.
