Although a better title for this should be "How is the rust going to make your life miserable today". While changing the transmission fluid and filter today, the two parts of the filler tube were stuck together. Rust would not allow the O-ring to pull through. After much PB Blaster, twisting, turning and yanking, finally came apart, to reveal this in the bottom of the pan:



So these are parts to the solenoid connector lock. I guess the lesson here is be careful yanking the pan off because those connectors are in a very vulnerable spot. Seemed to be an easy fix though-- squash the female faston a little bit to make it tighter, reverse it on the solenoid so the ears are now visible then solder the connector to the solenoid.

Looking over, I seen the fuel line connector and retaining clip appears to be rust. Like all the parts are gone, it's just rust. If I sneeze at it it will just blow away.

Amazon 52100349AB. Oh well the UPS guy hasn't been here in a couple days. That part already had a splice in it where it had cracked under the bracket on the engine, so now I feel a little more justified in dropping the 50 bucks.

Shoulda got a Florida Kee.

Not to rub salt in your wound, but there is no need to drop the pan on an AW4 to service it. It was designed for drain and fill every 30K miles under normal duty and every 15K under severe duty like postal delivery, lots of towing, or taxi etc.

Unless the pan is leaking, leave it alone.

Yeah, needed a new gasket as the front was a little leaky. Plus wanted to take a peak at the magnets. My minivans (particularly those with A604s) generated a lot of metal dust, so it's something I like to keep an eye on.

A604 vs AW4 is a crappy comparison of trannies. The only thing they share in common in any way shape or form is the "A" in their name..............

But A604 got better. I put in a used one in my 95 and ran it to 250,000 miles. I had a 2000 that had an early sensor issue that was replaced under warranty and ran it problem-free for 311,000 miles. And then a 2006 that I sold at 236,000 cause it's my wife's and she drives at night, so we need piece of mind. That one had an issue once but forgot what it was...

Got the new 9 speed automatic now. We'll see how that goes.

Both also end in 4

IMO I think the biggest problem with A604 was the owners. Those transmissions were VERY sensitive to ATF types. I always used Mopar ATF. Those people who used anything else usually had issues.

I was service manager at a Jeep Chrysler dealer when the A604 came out. Now you understand my bias? Lol.

I unbolted the mount for the filter time and dropped that with the pan since the tube would not disconnect for me. That is an option to those in the same situation.

awg

If you are saying you undo the one bolt that retains the filler tube to the engine, and just drop the pan & complete tube as one..that is what I do to...too easy!

it can be wiggled completely out if the vehicle is high enough off the ground...jackstands are enough

Dumajones

Yep,, let it hang if you can't separate the two tubes that make up the one.. A little Heat usually helps pop them apart.

But if to much of a pain or no heat..let it hang.
