Angry Cannot get 4l60e trans filter seal out suggestions...

Well it has been the better part of two hours now fighting with my trans. I started by draining the stock pan, which as everyone knows, is not fun due to trans fluid going everywhere because the stock pan has no drain plug. So after getting it all out and dropping the filter on my 4l60e I seriously cannot get the old seal out (rubber/steel ring). I have tried just about everything I can think of with no success. Is there a specific tool I need in order to get the job done? Any suggestions would be helpful as I do need the car back together in the next six hours. I think I am gonna take a break because I am about ready to take a hammer to the damn thing.

I use a small precision flat-head screw driver ( like the kind used to work on watches) to pry just behind the seal. Gently pry it out just enough to get a small pair of locking surgeons' pliers on it. Then lock the pliers on the seal and twist it out. Just be carefull not to damage the soft aluminum in seal/filter cavity. I have done this about 7 times between all my cars with the 700/4l60e. There are other ways I am sure but this works best for me. Although the tranny fluid on my fingers doesn't make gripping the handles any easier. Hope that helps.

Why take the seal out? It's permanently pressed into the pump cover for a reason. It should not need to be replaced to do a simple filter change!

its not permanently pressed in. The seal comes with a rebuild kit.

but i agree that you don't need to take it out after every filter change. I have only seen that seal worn out one time.

If you want to take it out you need a screw driver with a fine flat head or a bushing cutter and a hammer. collapse one side of the seal and pull it out with a pair of pliers or a scribe.

If I recall, I removed it by simply screwing a 1/2" standard brass pipe fitting into it with a 90 elbow on the end. Then hit the inside portion of the elbow away from the pump to literally pop it out. The Tranny repair video describes this little trick

Place a long thin screwdriver on one side of the filter seal, and tap with a hammer (straight in on one side)...
this causes the seal to rotate (screwdriver pushes in one side, the opposite side comes out)...
use long nose pliers to grab the side that is sticking out, and pull down and out.

"but i agree that you don't need to take it out after every filter change. I have only seen that seal worn out one time."


I guess you missed this statement that I agreed with. Sorry if I made you angry! I would not normally replace the seal either unless the filter had very little resistance inside the seal. I do however replace the seal on all of my rebuilds. Is this the wrong thing to do from an engineering stand point? Vince

No. But damaging the seal bore of the pump cover is a concern if not done carefully. An average owner using a screwdriver and a hammer during a fluid and filter change is definitely a risky manouver.

I guess I took offence to the "stupid" smiley. I'm OK now.

yep im a builder, at least i try to be. lol.

like i said ive only seen that seal worn out ONCE, it was in a 4T60e. The filter was sitting in the pan when i pulled it off.

With that being said, i dont normally change the seal, only if its worn. Just gotta make sure to clean around the seal really well.

to darknight:
the seal is NOT permanently pressed in, that was my point. The seal my have been designed to be maintenance free but that doesn't make it permanent.
