Could be that some of you discovered the white oil pan below my Chrysli. The oil inside is red and quite clean. So I guess it's transmission fluid. Today I took a closer look and I noticed that some heads of the screws holding the oil pan show oil drops. It looks like oil is leaking through the thread of the screw plug at the picture. What's the job of this screw? Do I have to use Teflon tape to seal the thread? I noticed that one head has round corners from a 13 mm wrench.
I took a 1/2 socket and a ratchet to check the screws and tightened almost every a little bit more. Any advice is welcome. Thank you.

Happy Motoring!

Dieter

According the Service Manual it could be the Throttle Valve Adjusting Screw plug. Is the thread self sealing or does this thread need some sealing, e.g. like RTV?

Teflon pipe thread sealer a small amount will do.

Looks like your oil may be coming from the shift cable.
Spray some solvent on everything and blow dry.
Then splash some talcum powder on everythging in sight.
wait a while and reinspect. The oil wil discolor the powder
and you will be able to trace the oil right back to the true source of the leak,

It's the shift cable. The leak is actually coming THROUGH the cable, not around it. The rubber coating is no longer sealing the cable.

I've been fighting that battle for years, and I can't seem to win it. I have heard that if you remove the cable and cover the bottom two or three feet with heat shrink tubing and seal it to the transmission case with RTV on reinstallation that the leak will stop. I've been too busy with other stuff to try that.

I've also changed the pan gasket countless times, sealed the neutral switch, everything. It's the cable.

Thanks a lot for your answers. Yesterday evening (night) I removed the plug for a very, very short time not to loose much of the transmission fluid. The thread is wet, so I guess there are at least two sources of the leak. For sure, the shifter cable is leaking, too. It's what the shop owner (so called mechanic) told me about a year ago. But I didn't realize that the leak is that severe.
I think the heat shrinking rubber tube could cure the leak, when applied at the correct position. Or soap the area around the connecter and use RTV...

Happy Motoring!

Agree with both of the last two comments, the same thing happens on 50's/60's British bikes that take the speedo cable from the gearbox.
The rubber just doesn't seal anymore...

Brians repair method works good but you need to use a thicker shrink sleeve with glue on the inside. Normal shrinksleeve will soon let the oil seep through in between.
Degrease the cable for the glue in the sleeve to adhere properly and indeed sleeve the cable about 3ft/1meter or so as the inner cable can,
when rotating, in some cases "screw" the oil upwards into the cable...
Cover the old connection of the rubber to the metal and as much of the metal end piece as possible..

Hello Dieter I had the same problem and I think the best way to fix it is with Wurth heat shrinking tube because they use glue inside the tube .I think it should not be any problem to buy the tube in Switzerland after all it is a German brand.. i think.

Thank you very much for your answers Dave, Brian (Ply57), Eric and Anders. To insert the shifting cable into the ferrule tube (/w glue inside) I assume to disconnect the shifting cable first at the transmission side. Is my thought correct?
To disconnect and remove the shifting cable I assume it's mandatory to drain the transmission and remove the oil pan, correct?

If so this makes me very unhappy. Why? At the shop the owner mounted a new pan gasket and refilled the transmission. He told me about the leak at the shifter cable, but he didn't ask to fix or intend to fix the problem.

Happy Motoring!

Dieter

Hi again you do not need to take the oilpan down you just remove a little screwplug on the side of the cable inlett and then you put a little radio screw driver in the hole and releases the cable.If you got a workshopmanual you can see how it should be done.When i took out the cable on my car i only have to catch cirka 1-2 dl of transmission fluid.(Depending on which side you put the jack. )When you mount the cable back you only has to push the cable back into the hole and you will feel almost like a little click when it goes in the right possision.

I'll try this week. Good luck - not far away (almost walking distance) from my working place there is a Wuerth shop. I'll try to get a Meter (3 yards) piece, because the online shop only addresses 100 mm pieces.
Did I understand correct to remove the screw at the side of the shifter cable insert and use a thin screw driver to free the lock pin to dig out the shifter cable? The screw driver length wise along the shifter cable - I guess - or through the open hole of the screw I removed? The procedure the '56 Service Manual (p. 298) addresses is far more complicated.

Happy Motoring!

Through the open hole of the removed plug .If you use a flashlight in it you will se how it works. It is a kind of spring that snaps into the cable .(Hard to explain due to my bad English) //Anders

I went to my Chrysli last Wednesday evening to replace the p/s pressure hose. I drove my Chrysli back to get access to the white pan. I cleaned it completely. Today I went to my Chrysli again. I noticed small drops at both ends of the transmission (close to the engine and close to the brake drum), but not under the position where the shifter cable enters the transmission.
On Wednesday I let the engine run for few minutes to check if all connections at the p/s are sealed. I pushed every button until I got to the N again. After that I checked the level of the transmission fluid: about 1/4" above MIN while the engine still was running.

Happy Motoring!

Yesterday I was able to use a car lift under the sky. After draining the engine (oil pan) We (Mike and me) tried to remove the shift cable at the trans side. I removed both, the neutral sensor and the plug ahead (at the left hand side). I removed the clamp (adjusting of the position and push button), But both we couldn't see the snap spring to open to free the shifter cable. After about half an hour I decided to assemble all removed parts and adjust the shifter cable again. I guess next time I'll remove the trans oil pan.

Now the question: the cable looks quite new, but the o rings.. what size and where from? I'll appreciate your answer very much. Thank you.

Happy Motoring!

Dieter

BTW: Mike's the owner of the lift and a car mechanic - he showed me many areas where there is no color at all under the floor... especially inside the braces. So I only have a nice weather car... no wet streets anymore.

Once you release it the cable should pull right out. I've never had a snap spring retain the cable in place.

I removed the hold down clamp and pulled and pushed and pulled and pushed. I noticed the movement of the valve ( mode of the transmission). My Service Manual addresses the snap spring and how to use the screw driver. I didn't have the manual at my hand yesterday. According this manual it's only necessary to remove the neutral sensor, but not the plug.

It is a spring clip that locks the cable to the valve body adapter, there is a littlle tang on the clip that must be bent back slightly to release the cable as you pull on it slightly the trans should be in low to bring the cable out as far as possible to access the clip.

Dieter could you snap a picture of the area around where the cable comes in with whatever you have holding it in place? I can't find a picture of what the cable locking device looks like and you just can't see it in the picture you have above. I have a similiar problem with my powerflight and I need a point of reference.

You're right - I forgot to push the "Low" button prior to try to release the control cable. The Service Manual shows a picture at page 298. I think the point is to guide the screw driver (or what ever it is) diagonally through the neutral sensor hole. The handle is pointing to the right side, the tip of the tool to the left side (inside the transmission). I tried only pointing the screw driver straight (90 degree angle) to the case. In this position neither me nor you could see the mechanism and the spring to release (except the oil pan has been removed).

Happy Motoring!

Dieter

BTW: In my case it was only necessary to adjust the cable and bracket until all radio type push button were working like before.

Yesterday before I cleaned the pan below my Chrysli completely and yesterday I only noticed one mark inside the pan. It's at the front in the center, below the torque converter case. I do not say that it's the only leak, but this leak looses faster than the shifter cable. - Some work for the next winter... just a gasket set from Fatsco or ...?

Happy Motoring!

Today I checked the oil collecting pan again. Now it seems there are two leaks.
a) as addressed the front and
b) at the rear (governor ?)
but not at c) the control cable. It could be that the oil level is a little bit low now due to the leaks.

The last pics tells more than words ... it seems it's time to look for a new location.

Happy Motoring!

Dieter

BTW: the blue things are magnets as used at the refrigerator door - I'm trying to hold eventually existing metal debris back.

The second leak is apparently not at the governor area. Instead - it's at the intersection filler tube/oil pan. I guess I could solve this leak quite easy. But to replace the front gasket I have to remove the transmission - alone, uuhh?

When I worked on the bench I saw lots of leaking pan gaskets. These darn cork gaskets are easily damaged when tightening the retaining cap screws. I would use red or black RTV on both sides of the gasket and be careful not to tighten the screws to a point where you are squeezing the gasket enough to crack it. You may first need to straighten the oil pan where the bolt holes have been dented in.

For my car I found a piece of 1/8" silicone material and cut a gasket from this. No leaks.

The plug in the side of the 55 transmission case is a pipe plug and can be sealed with Teflon tread sealant. I would use the paste and don't over tighten. Using Teflon tape reduces the friction between the mating parts and one can easily over tighten a tapered pipe thread.


If anyone is interested, I have made a page/procedure for a repair to the shift cable on 56's and up. 55's used a lever on the dash and linkage to the trany.
