Does this sound like a failing torque converter?

I'm running a th350 in my car. It makes a horrible sound when you put it in gear, but it goes away above idle. It only happens in gear, park and neutral nothing at all.

It's not a metal to metal sound, more like a squeaky wheel on a shopping cart

Without hearing the noise,have you been driving the car and is this a new sound. HRP

 

I don't drive it much. But it has been going on for a while. Want to get it fixed right away because I'm taking it on a trip in a few weeks.

I know it's damn near impossible to describe the sound and have someone know what I'm talking about. I'm hoping the whole "only noisy in gear not moving" thing could be enough to diagnose the problem

do you have a inspection plate where the transmission hangs down below the engine,if so remove it,check to see if all the flex plate may be rubbing against the inspection plate,,the can easily bent. HRP

 

No inspection cover. That's on my list of things to do yet.

Exhaust pipe or something rubbing? Putting it in gear may be making the engine wiggle enough at idle to rub the pipes on something, above idle it smoothes out. Motor mounts? Lots of things could be making a shopping cart wheel squeak.
Have someone put it in gear while you lay BESIDE the car and have a listen to see if you can zero in on the source. Stand beside the car with the hood open and do the same.

 

Check for a cracked flex plate you will find your noise!

 

X2 on the cracked flexplate. I had one cracked completely in 2 pieces once. The puzzle like crack kept it still "working" (driving) but made some awfully funny noises.

 

I figured its either a cracked flexplate or bad torque converter. So I tried to pull the TC by just sliding the ****** back. I got the ****** back far enough so that the converter came off of the shaft. (I didnt have enough room to get it out, I will have to drop the ****** tomorrow) When that happened a chunk of metal fell out that looks like it use to be a ring, its either some sort of collar or part of a bearing. Perhaps it was a fin from inside the TC?

I'm not sure if it broke out of the converter, or it broke out of the ******?? Not knowing the ins and outs of the automatic transmission I gotta ask. Is it possible for a piece of the ****** to come out through the front of the transmission pump? Or did this definitely break off from inside the torque converter?

 

picture of piece...?

 

The side with the sharp tooth on it is a shear point

could it be part of the collar off the t/c?...I don't see how anything could get from the inside out into the ****** without a big hole somewhere...

 

Is that piece of a seal-saver?

 

What is a seal saver? Tried a google search but am still lost

A seal saver, or a Speedi-Sleeve is a very thin tube of metal, which is placed over a wear groove, where a seal would ride, proving a new seal surface.

 

Here's a torn up one:

Sure looks like your piece could be part of one.

 

I thnk we have a winner! So this came from the ****** side then?

This is what I was thinking. Can you please give us a picture of the torque converter where it goes into the trans? That is likely where it would have broken off. Never heard them called seal savers before? ?


sent via cl***room note. p*** it on

 

It's hard to tell from the side-view photo of the piece of shrapnel, but I think its a piece of the pump bushing. Although they don't usually tear-up like that.
Converter necks are precision ground pieces, to fit into the front seal, pump bushing and pump gears, when they go bad they are replaced. I would very much doubt anyone would machine and install any kind of Speedi-Sleeve (cheaper to get a new converter). We'll see when you get the trans out.

 

Inside of converter. Not a sleeve. Bearing casing. Dodged a bullet there, I really have no interest of the inner workings of a th350

Now to try and find the rest if it

Well you might find some in the pan, (time for a service, use a br*** screen filter). but I would want to remove the pump and check it out too.

 

****** is out, now is the time to do it

Subscribe cause I don't know **** about automatic trans! My tag says "3PEDLS".

 

For DOM,

If you ever need to replace a pump gasket and don't have a dedicated pump puller you can do this. It's a pretty common place for a leak, most people ***ume it's the front seal leaking, replace the seal, the. Get pissed off cuz it still leaks.



Upon further inspection I didn't find any pieces inside the pump or ******. ATF is purple, but I put an additive in it about a month ago.

Now to change the filter

What's this white seal called and can I get it locally?



Posted using the Full Custom H.A.M.B. App!

 

Those are called seal rings ****** shop thing. You need to look at the front pump bushing make sure its ok that's what the peace looked like.

 

All checks out ok. Guess I'm going to ****** shop tommorrow

If the sealing ring was broken when you pulled the pump out I ***ume you checked for a ring wear inside the high gear drum. If you're replacing a pump ring, they should all be replaced with scarf-cut teflon ones.

 

I read an article where they replaced all the rings with Teflon ones, even the metal rings. They also left out what would have been the middle steel ring claiming it allows for more pressure.

I looked at everything and didn't notice any scoring or wear. I replaced the pump o-ring and gasket not long ago, I may have just messed it up putting it back together.
