2004 Nissan Sentra Transmission Problem Diagnostics and Fluid and Filter Procedure

[Fitz98]

My son called me and said he is having a problem when his 2004 Nissan Sentra 1.8 sits overnight and he starts it in the morning, he has troubles getting it to engage into drive. He shifts it through the gear range a few times and it will engage eventually. After the car warms up, he does not have problems getting it to engage into drive. No CEL and once engaged, everything shifts fine while driving.
The car has approx. 220k miles and I don't think the transmission has ever been serviced.
I figured a good place to start would be to change the transmission fluid and filter.
Does anyone have the service procedure and torque specs for this process? A little bit of searching seems like the valve body needs to be removed in order to change the filter.
Any other ideas what I might look for? It would be nice if all I needed to do was to change the fluid only. I only have a couple days to do this work. He is coming home for the weekend and needs to leave in a couple days to go back to university.

I had a 2006 version of that same car. I switched the trans fluid to Maxlife, and it shifted like crap after. I don't know about the filter, never changed it on my car, but if given a do over on the fluid swap, I'd spring for the OEM Nissan-D fluid.

He also said that when the morning temps are colder (By North Florida standards) is when he has more of a problem. On warmer days, he does not have a problem.

Check the fluid level, Add fluid if needed.

If the fluid level is okay....There's an issue with the Forward Clutch (Hardened apply piston seals, Sealing rings, etc.), Servicing the unit will not correct this & will eventually fail to go into drive at all.....Likely at the worst possible time.

Those old Jatco's were decent units but 22 years & a quarter million miles in hot climate will harden some lip seals!

Normally I am not a fan of additives, but if this turns out to be a possibility if fluid level is O.K, is there something that might help get some extra life since this seems to be an early symptom? Maybe AT 205?
Looking for some quick temporary fix to get a little more life while I search for an alternate vehicle or replacement trans or repair shop.
Side of car recently got smashed (fender, door and rear quarter damage) so not sure if it will be worth investing too much into this one.

We used to call this "morning sickness" back in the day. Agreed that a fluid change is unlikely to help at this point.

Is this the same car that had the COLD steering problem? How did that turn out?

Thread 'Need Diagnostic Help With Steering Problem - 2004 Nissan Sentra'

I have an intermittent steering issue with my 2004 Nissan Sentra 1.8.
Problem is mostly when the engine is cold and at startup and the vehicle is at rest. Problem seems to go away after things warm up.
When starting the engine at the beginning of the day, the steering is "choppy". It will have a smooth easy rotation, as it should, for part of the turn of the steering wheel, followed by hard resistance for part of the turn, then easy, then hard.
It is more noticeable approaching full lock to left and right. It happens in both directions of rotation.
The steering fluid level is good, the PS...

I would start with draining the transmission fluid, dropping the pan, changing the filter and refilling with the appropriate fluid using the Nissan procedure. I bet that'll make a big difference.
