I'll update this thread since I want to keep these two issues separate. I tested the PCS solenoid wiring. PCS resistance is within spec, and the wiring to the PCM is good as well.

I did play around with the FMC values however, and discovered that lowering them to raise line pressure for low torque sections of the table causes me to no longer slip going into 1st gear.

All these symptoms (including the stuck TCC code) seem to be pointing to a clogged PCS solenoid. Oh, and no fluid coming out of the vent at the top. I have a leak, but it seems to be coming from the bottom pan gasket.

In your other thread you described the slipping differently than I had read in this thread. This comes to mind.

That'* pretty much exactly the problem I'm having. Where do I get this input clutch piston seal, and how difficult is it to replace it?

Well..after you have the trans out of the car and 3/4 of the way disassembled, ya pull out your clutch compression tool to remove the clutches etc etc.

So basically I need an entire overhaul/rebuild of the transmission to resolve this issue...

What other tools do I need to get that far? Is this something I should even attempt to do?

Can't see many images since I'm at work. Can you combine these two threads? Might as well at this point.

What would you recommend at this point? A full rebuild, a new transmission, a 5 speed swap, having someone else rebuild it for me? I've never done this before, nor do I have the tools for it. Any advice?

I went at it. The tools I got were a clutch compressor tool, input/3rd assembly o-ring compression sleeve (for the teflon rings), a tub of trans goo (more than you'll ever need) and the ATSG manual for the trans.

Used a bit of ingenuity to replace some of the various seals and I was rolling. Overall I wouldn't call it hard. It'* tedious and time consuming. Especially the first time. You'll question everything twice and then stop to say "hey...that'* how that works, cool"

Tough to say what to do. There'* frequently built transmissions going up for sale on the various forums. Maybe a JY one treats you better in round two, I'm unsure what advice to give you as far as how to proceed.

If you were local, I know what we'd be doing.
