Hello all,
I am preparing to change the transmission oil in my '08 with 95K miles on her. I dont know if the previous owner did a change on it or not.

My plan is to do a simple drain and fill and repeat that every few hundred miles until i get fresh clean oil coming out. However, i am not looking forward to removing the drain plug that often. I am wondering if anyone has fit a Fumoto valve to their transmission? I heard somewhere that the drain plug for the transmission is the exact same one as the engine oil drain plug. If so, perhaps i can use this Fumoto valve to ease things up quite a bit?

The relevant size for the Nissan Titan is the F103, or the F103N. Wondering if my assumtion that the drain plug is the same as engine drain plug is true?

I would not suggest installing a drain valve on the tranny. Potentially too much to go wrong for a plug that doesn't need to come out very often. When I did mine, the ONE time in 140K that i have (At roughly 110K) I drained, measured, replaced, drove around town 15 mins, drained, measured, replaced, drove a bit, drained, replaced and now the fluid looks new. As a disclaimer, i had a smoking sale on Valvoline max life synthetic locally at the time.

Just seems to me that it's too risky, as the oil drain is on the side of the pan and semi-tucked, but a valve on the tranny would hang straight down, prime for catching something lying in wait to snap it off.

I agree! That does not seem like a good idea at all.

If the drain plug on the transmission pan was out the side instead of on the bottom I would consider doing this. I'm a big fan of these valves. I have installed them on my engine oil drain as well as the radiator drain.

Get an 8 liter Mitivac fluid extractor that is air compressor driven, MV7300 series. Benz and other mfrs have been using these for years instead of fooling with drain plugs etc. and the see through body tells you exactly how much you pulled, so you know how much to replace. I use mine for tranny, brakes, oil, dif. Cars and M/C. Cost around 100 bucks. I don't know what a fumoto costs, but I'm pretty sure it doesn't do what my Mityvac does.

That's a good solution. There have been a number of times a fluid extractor would have come in handy.

Wow thanks for that tip. I have been unaware of the MityVac. Sounds super useful and clean. I have messed up the threads on the drain bolt of motorcycle and have always been paranoid ever since.
Question:
a) Does this reach all the way into the innards of a motor or transmission? I see that it has soft extensions that should get into tight places. Does it get everything out?
b) Why have i never seen a shop such as a jiffy lube or dealership use this if it is more efficient?

Another question:
given that most manufacturers say to "drain and fill" transmissions, and not "flush", what kind of extraction does this pump do for transmissions if it is connected to an air pump like the Mityvac 7300 series?

Given that the regular Fumoto 103 (as compared to a 103N) looks barely 5mm-10mm taller than a regular drain plug, do you guys think it will really risk damage to an already tall Pro4X that never gets offroaded? Ofcourse, i dont want to invite trouble, but it doesn't "look" that tall.

I don't care for the nipple-less Fumoto drain valves. With the nipple I can attach a hose and then put the other end of the hose into the opening of my drain pan. I get zero splashing of fluids. Without the nipple you can't attach a hose and you'll get splashing.
