Transmission Question

[Grizzle]

Driving home yesterday the rubber plug on the front of the transmission (to the right of the torque converter) failed.

After the inital white smoke screen, I was able to limp it home.

I contacted the LR service center to locate a replacement plug.

Sure enough, they will have to order a replacement plug.

However, they indicated that the plug is actually an access for the torque converter bolts and not designed to hold fluid or pressure. They believe that the failure of the plug indicates more serious tranmission problems.

It is a 1999 D2.

Any thoughts?

I would agree with them. There isn't any fluid in there, and it is there for access to those bolts. What kinds of sounds are you getting?

 

[Grizzle]

No sounds or slipage.

Just driving down the road and fluid began flying everywhere.

Are you certain its transmission fluid? I'd start looking at the lines or in other places. Have you checked the fluid level?

if it is trans fluid and it is coming out of the bell housing then you have a bad seal at the pump. There is a large seal that rides on the drive snout of the torque converter in the front of the trans pump. you will need to drop the trans to change this seal...no other way to do it.

Transmission shop is also indicating that it is a bad seal on the pump. They feel that there has to be a reason why the seal failed (pump problem).

How difficult is it to pull / install the transmission myself?

Obviously the transmission shop wants to rebuilt the transmission. Can I have them just fix the seal?

Seals can fail for a rew reasons. The most common reason is too much fluid. Seals can be slightly damaged during assembly. Especially seals on the pump. Obviously if you're leaking fluid, that means fluid is missing in the transmission. having less fluid than ideal, means the fluid you do have will heat up quicker, which won't take long to cause excessive wear on your 2/4 and low/reverse clutch packs. It is not a bad idea for a rebuild or even just a look see. I'd talk to a LR dealer first, as they may have seen severe transmission cases, and will better guide you on suggesting a rebuild.
