No sludgy coating on the filter. The fluid definitely had a brown tinge but hadn't clogged the filter so I don't think it's what you were referring to. (see photos).

Just learned about it yesterday, and am considering it! I'll report back if I do it, and if things improve.

A friend did the kit, and reports it improved his van (200k+ miles) performance substantially. Mostly related to poor TC clutch take up.

See if this helps. If I remember, the conductor plate just pops off as it is held by plastic pieces built onto the plate

Replaced the conductor plate 2500 miles ago on the 05 T1N at 188,000. The transmission has shifted great ever since. Holds in low gears up grades longer before up-shifting and automatically downshifts earlier relative to engine load. (though I still manually downshift to 4th often). It seems to have adapted better to my driving style and the rumble strip noise (RSN) also improved.
I never conducted the conductor plate autopsy, but the visual inspection showed iron filing build up and browned leads that I suspect were losing resistance and/or solid contact where the solenoids poke into the leads.

I was performing this service to try and correct some issues I've been having and during disassembly I cracked one of the plastic solenoid covers on the valve body. Does anyone know where I can find a replacement? More info and photos here: https://sprinter-source.com/forum/sh...61&postcount=1

The thread that Troll [Not "The Troll"] directed to ultimately revealed that the cracked plastic covers in question were deleted on newer OEM replacement parts. The covers are not needed.

There is a DIY method to check that the transmission solenoids are functioning over and above just checking the coil ohms.

Thanks goes to BenJohnson, and of course the Youtube video guy.

Transmission Valve Body - "pressure" test those solenoids!
