Left Filter Seal in Transmission

[630amichael]

I’m just now finding out there’s a metal ring inside the transmission filter seal that I didn’t remove properly. I tried my best to cut it out but didn’t realize there was a metal core. I didn’t have too much trouble pressing in the new filter. How much damage am I doing until I can get back in there?

The exhaust is welded right under the transmission pan so I couldn’t
remove it to change the fluid. Had zero working room so I need to get the exhaust moved over first so I can install my new pan.

What transmission?
Is this on the filter pick up tube?

They usually have a regular rubber o-ring, can you post a pick of the uninstalled new part?

700R4. Generic picture of the filter but that’s it. The metal core of the orange seal (red arrow) is what I didn’t fully remove last filter change. Thanks for the help

I’m more familiar with th400’s and it’s been a looong time but I thought that seal was strictly rubber.

You have verified the metal core with a new one? Just wondering if, in a tight and hard to see spot, if you’re seeing part of the case itself.

Yes it’s a rigid seal. You can see the metal insert if you look carefully.

I use a flat blade screw driver, to pry the black neoprene and metal push in seal. Not hard to do just be aware of scratching the seal seat aluminum.

Drop the exhaust at the head pipes a lower down away. Or remove t case mount bolts and jack up t case. 2 different ways to get more room.

With 2 seals on filer it may be leaking air. Air bubbles in the pump will cause cavitation, which damages the pump.

Thanks for the tips Wes. I also read an offset flat head screw driver will work. I thought it was a rubber seal so was going about it all wrong.

Felt like it was driving funny afterwards too. But the 35s make it slow movin so hard to tell. Need to get it re-geared.

Also wanted to add there were no bubbles on the dipstick

 

[Wes Harden]

Yes, if there were a bubble issue it would be between the filter and the pump. After pump the no bubbles.
I should have mentioned, that the double gasket is not that uncommon. I have found more than a few with 2 seals during a service, none of these transmissions had failed

Thanks again Wes. This makes me feel better.

A lot of times you do not need to replace that steel sleeve. If the filter presses in, and does not wobble around a lot, then you are good to go.
