Transmission Filter Gasket Removal Tip

[johnsmellsalot]

I changed my transmission fluid a few weeks ago. It was almost impossible to remove the old gasket. I found a tool called a seal puller. It would've saved me 2 hours. It can be found at http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Seal-Puller-OTC_17631608-P_N3497_T%7CGRP2083_____

This is a picture of the transmission filter gasket.

That is a seal puller. For the pan gasket shown above, you just use a gasket scraper. In a pinch, you can bend a cheap screwdriver to make a seal puller or grind a hook in the side of the blade to pop a seal out.

Believe the OP is referring to the slightly deformed metal cylinder in the center of the picture. That's where the transmission filter connects. And yes, those seals can be wicked to remove. A tool like the one referenced would be a welcome aid.

Why not just remove the one from the new filter & reuse the old one in place since they don't want to come out?

That's not very OCD BITOG-er of you! You should be worried if the replacement was nitrile, buna-n, or silicone and discuss it in depth!

Yeah tom, but seeing that it is metal...

I use a small flat blade screwdriver and a hammer to get it close to the condition in your picture before grabbing it with needle nose pliers. I would be concerned a seal puller may damage the inside of the bore.

Great info!

I picked up one of these a few months ago from NAPA for something like $12. It made it simple to get the seal out of the timing cover on my f150 with the 5.0 motor.

No, it just has a metal sleeve. The sealing surface is rubber.

FWIW, I really like to use a two jawed pilot bearing puller (think mini slide hammer). It works awesome - I can have one out in about 20 seconds with no drama....

Good point Eric as I had forgotten about that. Back to the OCD BITOG-ways then!

I always replace them because they have rubber in them. They are always a pain. I am careful not to scratch the inner bore which makes them hard to pull out. I have 2 or 3 things in my tool box any of which I use to get that seal out.

Sometimes I really fight one and it kicks my booty for awhile, but then I always get it.

I just want to add that is not a pic of my transmission. I learned about the tool AFTER I changed my ATF so I had to get the pic from google.
