I need to add transmission fluid to my 4x4 99 tracker and cant find the plug. I hope its just low fluid because it wont go into gear it just keeps spinning and the clutch depresses but doesnt stop the spinning and let it into gear.

I'm assuming automatic transmission. Check your fluid level immediately. If low(hopefully the issue) add required fluid, start vehicle and idle a minute to pump fluid back through system and try putting in gear again. If this solves the issue then you most likely have a leak some where. If fluid level is ok, you will need to see a transmission specialist.

No fluids are consumed in any vehicle

Thinking something you know nothing about
& the real issues, should be addressed at a repair
shop or trans shop

If it is low on trans fluid, then most likely
the damage is done already, based on your
description.

If it is low, then at the very least, you repair the leak,
not just add fluid

check transmission fluid level could be low.if transmission fluid level okay and fluid and filter been changed every 21000 miles.code scan for transmission fault codes like faulty transmission range sensor.faulty transmission fluid pressure solenoid, look for faulty torque converter code or faulty tcm. if you see no fault codes.either transmission manual shift linkage loose or broken or you have internal transmission damaged.

A 5-speed Nissan Pathfinder uses a different type of transmission fluid from an automatic; therefore Dexron II is NOT okay. This vehicle uses "gear oil" --- specifically 75W-90 GL-4 if you have low mileage. 80W-90 or 85W-140 can be used if you are up there in mileage (closing in on 200K?).

This type of service needs to be performed from underneath the vehicle.

If you have a set of ramps, now would be a good time to get them out of the tool shed. Exercise care in driving up the ramps as they can be tricky with stick shift vehicles. Once on the ramp, put wheel chocks on the rear wheels, put the e-brake on, and if possible, keep it in gear (I use reverse).

Even without ramps, there is sufficient ground clearance from this SUV for you to check your transmission fluid. But then again, the more working room, the better.

On the transmission housing, you will find two plugs. One is at the bottom (drain plug), and one is higher up on the driver's side (fill plug). If you wish to add gear oil, simply open up the fill plug on the upper driver's side. If gear oil starts to seep out, don't bother adding any --- it's full. If no fluid comes out, stick your pinky in the hole and try to reach down and see if you can touch the top of the fluid level. Top it up, then. Gear oil usually comes in quart containers that have a long, pointed tip that allows you to "squirt" the stuff into the fill hole. Convenient, no? If the fluid level is so low that you can't even touch it, you might want to consider draining what's left (why add new gear oil to old sludgy gear oil? Otherwise, fill it up until it starts to seep out of the hole; then screw the fill plug back in.

I hope this helps; take care of your SUV.

SEEMS LIKE TRANSMISSION FLUID LOW.TRANSMISSION SLIPPING TRYING TO GO IN DRIVE.CHECK TRANSMISSION FLUID LEVEL. IF LOW ADD FLUID UNTIL YOU REACH FULL MARK ON TRANSMISSION DIP STICK. WITH ENGINE RUNNING A IN OPERATING TEMPERATURE.IF FLUID LEVEL OKAY.CHANGE TRANSMISSION FLUID AND FILTER IF YOU HAVE NOT CHANGED IN A LONG WHILE.A DIRTY STOPPED UP FILTER WILL CAUSE TRANSMISSION TO SLIP.CANT PICK UP FLUID.

It needs a fluid change,and filter,in the transmission,also,add a additive called LUBEGUARD from napa auto parts,when you ask for the additive,be sure to get the one for gm,this additive keeps the valve body slick,and moving,this is the problem,your filter,and ,or,the fluid is dirty,and causing hydraulic problems,and valves to stick in the valve body in the transmission.

Are you sure that it is oil and not transmission fluid? The stains can look similar unless you actually get down and touch the fluid. If it is reddish in color then it is transmission fluid, which means you have a leak somewhere in the transmission. Either way, check your transmission fluid level and make sure it is not low. If it is is low, add some fluid and bring it to a transmission specialist to help diagnose and correct the problem.

It does sound like your transmission is on the way out if the fluid is topped off and you are still having your problem. I may be able to offer some advise that may help you out though. If you go to your local parts store or I believe even local department stores automotive department sell it as well, what you are looking for is LUCAS Transmission fluid treatment. This stuff works wonders on worn parts in transmissions. If you add it to your transmission you will have to drain some of your transmission fluid first so as to not overfill your transmission fluid. I hope this helps , good luck!

Check you transmission fluid if its thin theres your issue if not it could be your bands or your torque converter.
