@title. I got engine and trans out already.

Should i go ahead and split the case and change the filter? Has anyone done it got a video on it? Does it just use RTV silicone sealant? I am at 154k miles.

Engine blew. Transmission was fine. Found a 3.7l from a 2018 for $500 with 20k miles on it so i couldn't say no.

filter is internal to transmission so unless your going to dis assemble the whole transmission part 558 is the filter its not easy stupid ford idea non serviceable filters, same for fuel filters they are in the tanks nothing external another stupid design. and People wonder why I love my 89 escort that anybody could fix best car out of 4 I own

You might want to make sure your electronics like the PCM, etc. will work properly with a higher displacement engine if your old one was a 3.5L. If it is then you might be running lean if the PCM doesn't know the engine has a higher displacement. An aftermarket tune will likely correct what needs to be corrected in the programming. As for the trans filter, I see this as one of those "while you're in there" items to replace if getting to it isn't a total PITA. The good thing is that trans filters can usually last a long time if the transmission has been well maintained (i.e. 60k fluid changes). The real problem child is the PTUs. They need serviced every 30k miles, ideally. They go bad fairly often if they are never, or rarely, serviced.

So the only place i could find where someone was opening the transmission was to rebuild it. It did not look easy. I am split now.
The fluid doesn't look super horrible and the engine was actually well maintained until the water pump gave out.
I am still debating if i should do it.

I wouldn't do it. Cracking it open and getting to the filter might cause more issues than just continuing to use the filter. I can't remember ever hearing of a transmission failing due to a clogged filter. Usually, if the filter is clogged then there has been a catastrophic event elsewhere to make this happen.

You have the transmission on the bench. It has over 150k miles. I would be rebuilding it if I were you. You did the hard part removing it. The clutches are worn, probably a fair amount of clutch material in the filter, the bores in the valve body are probably worn, etc. If you are super cheap, run it and see what happens. I personally would spend the time to have it rebuilt for the peace of mind with that many miles.
