Today my car started making a grinding sound, when I put the vehicle into drive or reverse. when I start driving, the sound disappears completely. if I’m going around 10 miles per hour the sound will start back up again, usually while turning. I read something that said a transmission can make sounds like that if it’s low on fluid. I added about a quarter of a quart of transmission fluid. the transmission fluid is a clear red, but I have noticed that it is low. I don’t know if it’s because it’s not hot enough to be high on the dipstick, about (quarter inch) onto the dipstick.

Is that any better?
If you know how to brake torque an engine/vehicle, then I would check the engine/trans mounts… A pulley or something could be rubbing against the frame etc…
Did you check the ATF with the engine running and on level ground? sounds like it was not warm enough to properly check the fluid level… Also did you get the correct ATF off the dipstick/tube, Nissan had about 5 different ATF’s to chose from back then, not to mention other brands… But yes, properly check the ATF level to make sure, and ATF expands the hotter it gets to a point… This may be a job for a pro mechanic to diag…

Im not sure how to brake torque and engine but im a quick learner and very willing if theirs youtube videos. I will check that… i didnt know their was different types of fluid if i were to use a generic automatic transmission fluid i think it was mercon 4 could it hurt the transmission? Because I went off the owners manual and filled it to the cold mark on the dipstick while it was idling ive done some mechanical work mostly on suspension aspects of the car never transmission work I just want to try if i can to do it myself but i was going to make an appointment to get it checked out
And please, there is no need for duplicate post…
For the DIYer, get on level ground, away from being able to hit/run over anything close, set the parking brake very hard, and with your left foot pushing hard on the brake pedal, put the vehicle in a D, give the vehicle some gas with your right foot, you will need someone looking under the hood with the hood up (Edit: do not stand in front of the vehicle, keep to the sides), and check for excessive movement of the engine, like jumping up, then out the vehicle in R again left foot firmly pushing the brake pedal , give it gas to see if the engine is moving around much… If the engine moves more than the motor mount should let it move or the engine clunks then you probably have a broken engine mount… Might check you tube for checking engine mounts…

OMG. And have them standing off to the side. Never in front or behind.
That might be too much for DIY. They all move some. “Excessive movement” is more of an experience thing. And I don’t have it. I’d be standing there scratching my head. Too much? Normal? Not enough? Ah, lemme make a video for dave!

Yeah yeah yeah, I know, all very true, but on my defense, I was trying to finish up so I could eat, meant to come right back and edit it but life got in the way… lol
Thanks for adding the do not stand in front of the vehicle…
Yes as Mr. Cigroller said, part of making sure you could not hit anything, included people, and here is a video about checking mounts… I think Tester has posted it before multiple times also… Lot of videos out there…
What year is your I30 (1996-2001) and what does the transmission dipstick/tube tag if still present say, or even the owners manual say???
How fast did you drive the vehicle after the noise started?? Wondering if you drove it fast enough to get it to 3nd & 4th gears??
Your RE4F03A or RE4F03B if 2000 and up transaxle does have a transfer drive gear and a transfer driven gear on back of the case that are held on the shafts by nut(s), it is possible that one of the nuts has backed off allowing the gear to walk around a bit making noise, but if it has lost 3rd and 4th gears, they do have some issues with that happening… Either way, best left up to a pro transmission shop…
Check you manual, but I think (been wrong before) that the cold marks on the dipstick are for the engine being at operating temp but not driven since start up, and the hot marks are for the engine being at operating temp and the vehicle being driven for about 5-10 minutes for checking the transmission fluid (ATF)…
Also, check to make sure your cv axles are seated in the transaxle and haven’t backed off any… 2nd–also possible this is an axle issue, but probably not…
Hard to diagnose a vehicle you can not drive, confirm the complaint and check out for yourself…
Yes, much clearer now, thanks.
I doubt the trans fluid level is the cause of the noise. Could still be another trans problem though. I expect you’re going to have to do a few experiments to narrow down the cause. How does coasting in neutral affect the sound?, turning right vs left?, pressing lightly on the brake pedal? etc
