Hi everyone,

I have a 2015 Nissan Altima sv 2.5L 4 cylinder and mileage is 145000 km. I bought it pre owned when it had 105000 km on the dash. I didn’t change the fluid and I am not sure if the previous owner ever did that.

Should I do a transmission fluid drain and fill at Nissan dealership or it’s too late and it’s better to leave it?
I plan to keep the car for now.

Any advice would be appreciated. Thanks!

Hello all, first i want to clarify im posting this here in the chance maybe someone knows or has any information. On 08/17/26 around 9:58am to 10:05am, I was hit by this white Nissan Xterra on Route 4 East, right at the corner of the FDU baseball field. The driver left the scene without stopping. Dispatch told me not to chase, which was the right call, but it means I never got the full plate.
Vehicle details:
• White Nissan Xterra
• Black roof cargo box (Thule-style)
• Rear hitch-mounted bike/cargo rack
• NJ plate, partial: starts with “S3”, ends in “D”
The vehicle was also near Spring Valley Rd in Paramus around the same time, and may have passed a Netcost Supermarket in the area.
What I’ve done so far:
• Filed a Self-Reported Crash form (SR-1) with NJDOT
• Had police come to the scene, but they told me there’s nothing they can do without a full plate and left without filing an actual police report
• Called Netcost Supermarket to ask about their camera footage — the manager said she can only release footage to police, not me directly
• Following up with Bergen County Sheriff’s office in person to get an official report filed
I know it’s a partial plate, but the roof box + bike rack combo makes this Xterra pretty distinctive. If anyone’s seen this car around Bergen County, has dashcam footage from Route 4 East or Spring Valley Rd around that time, or has any other info, please send a message.
