I am selling the van and want to fix this leak. What is involved in replacing this (my dealer and mechanic tell me the pack must be replaced even though the trans works fine) and can a guy with average skill tackle this or should it go into the shop?

Re: 2003 T&C Solenoid Pack leaks
Depends on where the leak is from,the top or the side with the torx screws,if it's at the top which is usually the problem the gasket is about 5.00 and you have to remove the breather assembly,and the 3 bolts from the top side and wire harness from pack has a 10mm nut holding the harness on,install new gasket,if you remove the torx screws there are 3 springs,cups,and spacers that will fall out so the spacers go into the screw holes and the 3 springs and cans are all the same size so order doesn't matter on these.

This is an automatic transmission issue which may involve replacing the valve body and solenoid pack and affects transmissions fitted to various Chrylser models. It could also be a symptom of more serious transmission problems and requires proper investigation and diagnosis.
On some models there was a Technical Service Bulletin issued to dealers on this problem .
A scanner will show you. Codes will tell you. Or pull them and test them with am Ohm meter. Could be the solenoid pack also. If you transmission leaks. When it gets to low, it will suck air. This will also cause your van to go into limp mode. Start the van and check transmission fluid first. Fill as necessary. Turn it off and disconnect the battery for 30 minutes. This will clear the computer. Drive it. If it stays out of limp mode. Fix the leaks and/or keep it filled. Those sensors run around $20 a piece. The solenoid pack can be around $200+ Don't buy a good used one.
Has any one of the mechanics you visited explained to you where the leak was coming from? If not ask them again to be more specific.If the reply is from the sump gasket then it is good to go to the second one as he already said that. To renew the gasket you have to remove oil and the sump also you can carry on further by renewing the filter and cleaning the interior of the gearbox.
Your Caravan is most likely equipped with an A-604 transaxle. The solenoid pack is the the box with the black cover on the forward side of the transmission where the wiring harness connects. It is VERY common for the solenoid packs to leak on those transmissions. so I believe the mechanic probably told you correctly.
You DO NOT need to REPLACE the solenoid pack. you need to RESEAL the solemoid pack. It is not very difficult to do and the seal kits are available at the dealer. Most aftermarket parts suppliers do not carry seals for these, but you can check with your local supplier if you like. It only take about an hour to do the job professionally, so if anyone tries to charge you any more labor than that, they are ripping you off.
Also there are some lazy, or inexperienced, or just plain rip-off, mechanics that might try to tell you that you have to purchase a complete solenoid pack.
Chrysler Solenoid Switch Valve Latched in LR Position (this is a transmission issue which may involve replacing the valve body and solenoid pack; on some models there is a TSB on this problem so be firm with your dealer / Chrysler).
Yes, The soleniod pack is located on the outside of the transmission. There are a few bolts holding it on and a seal or o ring gasket behind it. The lines mght look corroded and rusted, but if they are not leaking then leave them alone. The inside of the line is just fine. You may borrowing trouble trying to replace them. The fitting and line could be brittle. You may have to purchase the solenoid pack from the dealer not sure. I would check you local auto parts store for the part first. Once the solenoid pack is replace, The tranmission might have to be reset to correct settings. The transmission can be reset by your local transmission shop. The transmission shop may do the repairs for a lot less then the dealer. I would inquire for an estiamate from your transmission shop just in case.
I would lean to a simple transmission leak inspect your transmission housing for leak when vehicle is in the air safely on jack stands and wheels off the ground and rear wheels chucked.... safety first! start by visually inspecting the transmission housing for noticable links then if none can be seen or theres soo much fluid you cant tell where its coming from clean the area with degreaser and then reinspect after cars been running and shifted through a few gears this can be doen while vehicle is still in air as long as its done safely! locate the leak and replace parts as needed could be from pan gasket or differential seals or from speed cable from top, the torque converter or even can leak from fill spout but not likely after you locate it replace part from local parts store or dealer or just have it done proffessionally but most selas can be replaced by knowledgable do it yourselfer! good luck and dont forget your rating!
