Default 4l80e, does this fitting need this O ring?



I know the picture isnt great but best i can do...only have a camera phone and it is ****

Its the rear fitting for a 4l80e but the oring doent fit the case...can i just use thread tape and some thread putty and call it good.

Does anyone see a problem with this?

no, you don't need that oring, just use liquid Teflon and DON'T over tighten it, it will break the case.

Use bread it works!

Find something that fits tight in the hole so it will seal pretty well to use as a punch driver that you can hammer on. Then take bread and stuff it in the hole. Keep filling it and packing it in there with your punch tool. The bread will compact and hydraulically push the bearing out. Works better then grease and a LOT less messy,

The oring is needed on the factory fitting because there is no sealer used here. On the AN fitting use liquid Teflon as instructed and do not be a gorilla when you tighten it up. There is another fitting out the market that will allow you to use the factory one with the -6 an. Here is a link for you. http://www.purechoicemotorsports.com...rod/prd255.htm

I have also seen a new fitting out from TCI that has the extension tube on it with the -6 AN as well. You will have to look on their site to find that one. Vince

This one came from one of your FLT level 3 80e's wonder why it had the oring?

I thought it looked familiar. To be honest I never installed an oring on one of these AN fittings. If I had to guess I probably made the fitting and shipped it to our customer. At which point they must have installed the oring. This was probably before the above advise I gave you was available. Vince
