Transmission drain plug leaking fluid

Hi,

I see things that look like cracks, but I don't think they are. It's hard to tell from a video.

Try this: Get brake cleaner and clean everything off so it's dry. Then refill the transmission to see if you can locate the leak. Hopefully, this will help to identify where the leak is originating. I don't think anything is cracked, but it is possible.

If it is still coming from the drain plug, let me know.

I will watch for your reply.

Take care,

Joe

Hi,

Did you replace the drain plug gasket/o-ring? See pic below. Let me know if that was replaced.

Hi,

If you replaced the washer/gasket and it still leaks, inspect the area around the plug for evidence of cracks. Also, spray everything down so it's dry and clean. Then confirm the leak is from the drain plug. If there are cracks causing it, you should be able to see the fluid seeping through them.

Let me know.

Hi,

If you look below, there are two pics that include the torque specifications. I'm not sure if the vehicle has a 4 cylinder or a 6.

The first pic shows the torque for a V6 and the second pic is for the four cylinder.

Let me know if this helps.

Take care,

Joe

See pics below.

Hi,

If you replaced the gasket and torqued it to specification, there has to be a crack we are missing. You have confirmed the leak is from the drain plug, correct? I know you were originally questioning possible cracks.

Also, when you replaced the metal crush washer, was it only metal? You may want to try a nylon or composite washer/gasket in place of the crush washer.

Let me know.

Hi,

There isn't a pan. As far as the crack, that is part of the case. What I would do is this. First, you need to find someone that can weld aluminum and have that part welded back into place. Then they make "pan savers" that you can use to seal it. (See pic 1 below)

To replace that portion of the case, the transmission needs to be taken apart. I would at least try to do it this way.

I wish I had an easy answer. Please let me know if I can help you in any way.

Take care,

Hi,

You could try something like that. My biggest concern is it would come loose or if the housing has other cracks, the expansion may cause it to break more.

Let me know if I can help in any way.

Joe

I would want the broken part welded back to the housing and then use a pan saver. I wish I had a better answer, but there really isn't.

It's what I mentioned a few posts back. I reattached the pic below. If you weld it back together, either you will need to drill and re-tap the threads or use a pan saver. It basically works like a toggle bolt. See pic below.

If the weld is done properly, the absolute best thing is to drill and re-tap the threads and use an oversized pan bolt, but the pan saver will work as well.

Let me know what I can do to help.
