Hi pitch noise

[--No_turbo]

I have a hi pitch noise coming from the engine when im driving could it be the turbo or the tranny?

The turbo normally makes a high pitch whistle or whining sound that is only noticeable during low to moderate acceleration - not loud at all.

Is this an automatic? If it's the tranny whining - very low level whine is normal to a point. If you can jack the entire front of the car up. Then run the car through it's gears and listen underneath. If it sounds like it is coming from near the engine block, it could be the torque converter. If it's at the back of the transaxle - it could be something in the differential.

The Chrysler Shop manual says to change the fluid and filter if the tranny whines and the problem does not appear to be the torque converter. Check for metal flakes/shavings in the pan. There should be a magnet setting in the bottom of the pan. It is normal for it to look fuzzy with fine metal shavings. Though large shavings is a sign of problems.

Be sure to run the car in reverse, 1st, 2nd, and 3rd since each gear uses different gearsets and clutch packs to run in.

Well I got it up and foound the upper trafer gear is rubbing the cover. I have not pull it off yet because I dont what to see behiind it. What could cause the upper trafer gear to rub?

[JohnnyLightning86]

What do you mean by the transfer gear rubbing the cover? Do you mean differential? Is so, you can easily pull the cover and look inside. Use Form-a-gasket or RTV to put the cover back on. Just remember that some fluid will pour out of the cover when you open it.

There are a number of gears in the differential. You should be able to set the trans in neutral and turn the wheels to look at the gears. Hopefully you will be able to see and hear what it is.

If it's something rubbing the differential housing, it might be the differential pin. Been doing many one-wheel burnouts? I understand that can cause the pin to wear and come out chewing up the gears and trashing the housing. If so, it will need replacing. And if you do, be sure to get a set of pin retainers from RP.

The tranfer gears on the side of the tranny. Now the cover is showing a ring around the top gear from the heat build up what can cause the top tranfer gear to push out?

[JohnnyLightning86]

Transfer gears - sorry, I know what you talking about now. There may be some end-play along the shaft somewhere causing it to rub the cover. It's kinda late right now, so I will take a look at the shop manual tomorrow to see if I can find some possible problems. I'll get back with you then.

It's sad that there are a number of people on this board that know more than I do, but don't seem to respond with much information. Come on people, surely there is some one on here that knows a lot about these trannys and could possibly help more than I can.

I have not been able to find anything specific about what might cause transfer gear end-play enough for the gear to rub the housing or pan. Primarily the manual says to remove all 3 pans and check for debris.

As best I can tell, the transfer gear might push out for the following reasons, and I am speculating some:

1. When the transfer gear and/or output gear are worn. The manual says to replace them.

2. Remove the transfer gear - check for a worn bearing cone behind the transfer gear. Most any place that specializes in bearings can probably find a replacement.

3. Check for any wear near the end of the transfer shaft. If so, an overhaul would be required and the shaft replaced.

4. Inspect the shim behind the bearing cone - not sure of this would cause any problems though.

5. Behind the bearing cone there is a Governor Support Retainer and bearing cup (holds the bearing cone in place) Look for any wear in the bearing cup.

6. Behind the Transfer shaft gear there is a low-reverse band anchor pin sort of between the Tranfer Shaft Gear and Output Shaft gear. Check to see if it is out of place or pushed out and adjust accordingly. It would rub the back of the TSG if out of place.

The shop manual basically breaks everything down in to two categories - what to do when there is or is not metal shavings present which requires all 3 pans to be removed. And it pretty much says to do a complete rebuild if there are any metal shavings. Although, in every situation where there is gear noise or a whine, if there is no debris, it suggests cleaning the valve body.

Not sure if this helps, but might be worth checking.

Looking at this some more, once you remove the Governor Support Retainer, you should then be able to pull the transfer shaft out. There is another bearing cone at the other end.

If you do pull the transfer shaft, then also check the gear at the end for wear as well.

I could see if the bearing cones are worn, or if one of the bearing retainers is worn, that might cause some end-play in the transfer shaft. But I would guess, if it is anything, it would be a bearing cone or worn gear(s).

Thanks I found the problem the top tranfer gear can unbolted and with the curve of th gear it caused it to rub the cover hens metal shavens then dead. Not is all lost $250 installed a tranny and I back up a running in "6" hours YA!

But what caused the gear to con undone?? I've removed then and lets say the factory put them on the tight side!!
