So I've had a torque converter leak for a will now but haven't had the time or the money at the same time to get fix it.....so I just been making sure that I always have tranny fluid in the car at all time.

To the point.....just today I started hearing a whaling like noise from the car when I have it in drive or reverse. So could I have possibly burnt out my tranny?

Or could the noise be something else because the noise happened after I put tranny fluid in the car?

 

Did you overfill the transmission?

Does it engage properly when you put it in D?

 

c'mon dude, if it was leaking it was probably low and did damage. to what extent only a tranny shop will know. you could drain and refill to proper level and try resetting the ecu??

 

Everything engages properly R and D.
I didn't overfill it on purpose, I thought it was low because of the leak and put about a quart in it and it overfilled.

I know it had the leak but I doubt the leak was that bad because like I said I checked my oil everyday, sometimes two or three times a day. And I thought the oil was low but when I put a quart in it, it overfilled so my oil could not have been that low.

 

Oil???? You are talking about two different things here man, which is it that's giving you issues? If you overfilled the transmission, you need to drain some of that fulid off. You need to check the trans with the car warm, and running. Pull the dip stick (for the TRANS, not engine oil) with the car running, wipe it off, stick it back in and pull it out and read the level. It's not hard.

If you overfill the trans, the pumps inside the trans are under too much strain / pressure. You're asking it to pump too much fluid and yes, this will damage the pumps and possibly clutches inside the trans.

How do you know it was a TC leak? What proof did you find to help you come to this conclusion? Are you certain it wasn't another fluid?

 

I meant tranny fluid.
And my mechanic the one that told me it was a TC leak and I know how to check the dipstick but when I was filling the fluid it overflowed.

 

hence my first post, overfill will kill too. tranny fluid can leak a little and it'll be fine. my axle seals have been leaking for 2 years and i just keep my eye on the level and check every 2 months and look under the car as well.

 

If the transmission is overfilled there will be excessive churning of the fluid, creating air bubbles in it. Air bubbles in the ATF will result in insufficient hydraulic pressure to hold the clutches properly, so they will slip.

Check your ATF level as JtzMax wrote. If it is overfull, drain some out using the drain plug in the transmission pan - it is easy. Have some fresh ATF on hand before doing this, just in case you drain too much fluid and need to add some fresh fluid back in.

 

Any MIL on? any trouble code detect? Leaking not only lose fluid also lose workable presure,sure will damage to the tranny

 

Ok so I drained the fluid and changed to the right level and for that day the car didn't make the noise but this morning on my way to class it made the noise again. Usually when it makes the noise I'm not able to check it out because I'm on the highway or in traffic, but this morning I was able to pull the side to look at it and it's not my Tranny that was causing the noise.......the bearing in driver side fan is going bad so it doesn't spin properly causing that horrible whaling noise.

I plan on going to pick and pull today and getting a whole new fan set up.

 

oi

 

tranny fluid IS an oil ... im just sayin........

 

I am not sure how much my question fits this, but since last two weeks I am noticing shifting my 97 Auto from neutral is not going smooth and it seems while engaging engine is pulling backwards towards firewall. Today it was quite noticable which you can clearly feel seating in car, it happens for Reverse as well as Drive gear. Once you start and running you cant notice that ( but may be that may be because of lot other movements ) car is all stock 150K, have not flushed tranny fluid since I baught 3 yrs back with 107K on it and dont know when previous owner would have flushed it.

Is it a tranny issue ? just changing fluid should solve it ? how can you know how bad is it and how much more you can drive without fixing..


Thanks

 

Sounds like your motor mounts are shot. You have 4 of them. Check them all out especially the two at the bottom (front and rear of engine). Also what color is your tranny fluid??

 

Thanks for your reply Trini boom,

I tried looking in how to's of 4th gen but couldn't find thread on replacing / inspecting motor mount ? is it anywhere ? how hard is this DIY...I have done couple of jobs like sensor / starter / brakes replacement stuff....If i plan to get it done outside how much should it cost ( I am in nashville, TN )

 

cost of the mount (courtesynissan.com) plus labor. the one on the passenger side is easy, all the rest you need a jack so you can loosen mount to get it off and support engine while your swapping them up. mounts are 100.00 and up depending on which one. and, as many op have done it, get em new.

 

I have a question, how did you know it was a torque converter leak? I noticed a growing puddle where I park today. So I jacked up my car and think I identified the source, but I'm really a mechanical newbie.

Where the motor and transmission parts connect on the underside of the car, it seems to be leaking from there. I, using what little information I had, decided it was probably a rear main seal leak or my torque converter.

The fluid was brownish, but not dirty enough to be oil, as far as transmission fluid, I travel quite a bit and top off my fluids every 1k miles or so. I did recently need to drop about 1/8th a quart of fluid in. So the leak is slow, but it builds a nice enough puddle that people are complaining.

Any suggestions in further diagnosing the problem?

 

rms seal is common in our cars. i've put a couple of sealant stop leaks but what did it for me was replacing the trans and that slowed it almost to a stop. rms is not an easy job, the trans has to come out and there's 2 different seals in there that could be done. look at your pan too, thats not a real hard one to do. search man......

 

Tranny Problem?

 

I had a mechanic told me it was a torque converter leak, but one thing that really made me realize it was a torque and rear main seal leak was when I get on the highway and drive a long distant and come to a stop at a rest area my car was leaking hard.....it was dropping something hard.

 

Ok I checked and show that Tranny was not filled at required, so added fluid, Fluid seems not too bad, any way I am going to change that.

Another question, if your car is getting Thud at every change in gear ( auto ) as well as engine rocking in engine bay while shifting p->R->N->D, How can you perfectly determine that underlying cause is Tranny or Mount?, My tranny shifts smooth while changing ( you dont feel hard shifting ) but you get thud noise when it changes.

 

umm look at your mounts?

 

Get underneath the car and look at the mounts. If the rubber is ripped from any part, the mounts are no good and need to be changed.

 

Ok got all 4 mounts today, will get it replace tomorrow and will update....

 

Where did you get your mounts from??
