Recently Rebuilt 4R100 Slipping; can I just replace clutch seals?

[New2PSD]

I've got a 4R100 in my '99 PSD that was rebuilt 15k miles ago and is now slipping pretty bad.

The fluid smells burnt but when I drained the fluid and dropped the pan there was no metal debris and no clutch seal debris.

The trucks pulls hard in reverse but slips in drive.

Can I do a sort of mini-rebuild and just replace the forward clutch seals in it?

I've noticed that there are rebuild kits that vary drastically in the number of parts that are in them.

If I were to do just the forward clutch seals would I save myself from having to buy the special tools and maybe a bit of time too or are they buried deep in the transmission?

Thanks!

You would still need the OD spring compressor tool. You might get in there and find more burnt clutches and I would replace all burnt clutches and steels. It is not hard to build the 4r100.

I've never taken an auto trans apart but now that I have two for my truck I'm ready to take the plunge.

I see that tool listed for $165 on a website which describes it as; "Allows for quick Assembly/Dis-Assembly of the Overdrive Cylinder from the transmission case. It also assists with the Assembly/Dis-Assembly of the Overdrive Cylinder Diaphragm Spring."

Is that the tool I would need?

If you're going to attempt this yourself, this is a good read....
