new to the site! transmission solenoid.

[lincolnls2004]

alright, i would love some help from some people that have done the transmission solenoid change on the 2004 lincoln ls. i got the basic idea how to do it but ive read that the solenoid needs soaked before installed so no air pockets, what else is there to do to it before and after to make sure all is smooth shifting! all installation and removing tips are welcome. thanks in advance. also is the 700800 transmission website legit?

Have fun. I ended up bringing it to an independent transmission shop. The link above is for the 5R55N. You should have the 5R55S. Not sure what the differences are. Parts will be most of the cost, so doing it yourself will only save you about 1/3 of the total cost of bringing it to a shop. That may or may not be worth it depending on how much time it takes you, how frustrated you end up getting, and how much your time is worth to you. I enjoyed the peace of mind knowing a pro did it. Labor was $350. I provided parts.

I ordered a solenoid and valve body from 800700 and the solenoid was bad. I went to the dealer to buy a new solenoid thinking I could return the bad one. They don't do refunds, only exchanges. The guy told me quote "looks like your screwed then". I will never deal with them or reccommend them to anyone again. Ahhhh...another 800700 rant complete

I have never heard about "air pockets" or soaking the solenoid pack prior to installation.

700800trans is legit, but the solenoid blocks are not one of the better things to buy used.

The swap is pretty straight forward, but if this is your first time there will be a bit of a learning curve. The 10mm connector for the solenoid pack faces up toward the car and is quite a chore to get to. I have found that a ratcheting combination wrench cut down to 2-3" long is the right tool for the job. Start with getting that connector bolt off, and if you cannot you have not lost anything from trying.

If you do get it off, you will need to pop the shifter connector off, the O2 sensor connector off of the pan, and drain the pan. There are 16 8mm bolts, then you can pop the pan off. The solenoid block is retained with 8 T30 torx bits.

The other challenge is refilling the fluid. As long as you are in there, it is wise to replace the transmission filter and put some fresh fluid in there. There is a 5/16" allen plug on the backside of the transmission that you will have to pump the replacement (4-5 quarts) Mercon V into. A suction gun works, but does take some patience and a bit of a mess.
