If you have the manuals, here is where you may want to look
P0715 INPUT SPEED SENSOR A ............. TM-114
P0716 INPUT SPEED SENSOR A ............. TM-117
P0717 INPUT SPEED SENSOR ATM-119, TM-377
P0720 OUTPUT SPEED SENSORTM-121, TM-379
P0721 OUTPUT SPEED SENSOR.............TM-124
P0722 OUTPUT SPEED SENSOR.............TM-126
The input speed sensor is located on top of the transmission just behind the bell housing.

Thanks for the quick response. It’s not throwing a code but I have the ez-lynk autoagent and I have noticed my transmission output speed stays at 6,000 rpm. When it shows 6000 I have irregular shifting in 3rd to 4th. When it shows normal readings the transmission shifts fine.
Usually when it’s running “right” the shaft rpm runs from 1200-1900 rpm variably with the speed of the pickup. But right now at 5 mph-80 mph it stays at 6k. I’m curious at to what sensor on the transmission is sending that faulty signal so I can change it out and try that.

Another question till consider is whether the EZ-Link or other monitoring device/ software ia correctly interpreting the signal.
IF the monitor expects the signal to be within a certain range AND the signal is actually calibrated to provide a much higher signal strength ratio then as soon as the raw signal exceeds what the monitor was looking for it will read it's max interpretation, in this case 6k.

I thought that as well so I emailed the tuner and asked them to look into it and they told me they don’t do transmission tunes and I should take it to a transmission specialist so I’m at a standstill there.

Hate to resurrect this old topic, but im pulling the p0721 code. Where is this sensor located? I saw the above post stating ti look at TM-124 but I guess I don't own that manual. Any help would be great as my TC isn't locking out and my trans is overheating due to that when I haul a trailer. Thanks.

My 2017 titan transmission went out and has been at aamco since July. The bell housing was bad also the speed sensor. I was told that the wire to connect it runs through some kind of metal piece(forgot what he called it) broke off in there and that never happens to nissans and also the part is hard to come by. The truck doesnt have a 3rd gear because of it as well

Hey Josh, have you figured a solution to the problem you’ve been having yet? My Titan is doing the exact same thing. I’m deleted with the easy link and it goes right to 6k too. Also revs high out of 3rd and bangs into 4th. Really hoping to find the solution. I’m also getting a u1000 code and c1a03
So I never did find a solution I would say, what I did was unhooked both the batteries and let it sit all weekend.I changed the transmission fluid( make sure you put the same back in as you take out) I reflashed it to 60hp tune and drove like a normal person for about 2 weeks and it kind of fixed itself. The output sensor still shows 6k as soon as I push the throttle but it quit doing the slip out of third into fourth. I’m at 137k miles and hasn’t done it again. I think when I had the issue I was sitting about 60-70k miles.
