P1776 Code.. persistent, I'll give it that.
This is my first post, and I am helping a friend work on his 2004 300M, with the dreaded P1776 code. He tells me the transmission will shift fine, once he goes over 45 MPH, if he goes back under 45, the transmission will shift into 2nd and stay there unless he pulls over, shuts the car off and starts it back up. He's flushed the transmission himself, which didn't help, so he had it professionally flushed, which also did nothing. Now, we're gonna dive into the repair. I've worked on a lot of cars and trucks, mainly Fords and a few imports, so I know my way around and engine and transmission.
I've done quite a bit of reading on this subject, and I know that we're going to have to replace the solenoid pack or possibly the valve body. This is my main question. Is there any way to tell if the L\R is in the valve body or solenoid pack without pulling the pan and reading the date code on the valve body itself? We're trying to get our ducks in a row, so we can knock this out in a weekend. We live in a small town so everything has to be ordered online and takes a few days or a week to get here, so we'd like to have everything we need to do the job before we get started.
I found a write up on the replacement before I registered, and I'm still looking for it again...If I ended up finding the write-up on another site and this site doesn't have one, I'll be more than happy to create one (I've written quite a few for Fullsizebronco.com and Fordtruckclub.net). One thing I noticed on the write-up I did find, is that there was no mention of a valve body gasket or a solenoid pack gasket, anyone have any input on the best place to get these gaskets?
Thanks for any help or advice you guys have to offer. I'll continue my search for the write up and any other information on the repair. My main question was if we'd have to replace the valve body or the solenoid pack.
