E40D w/227k miles. Worth Saving?
I've got a '96 F250 with 227,000 miles. The transmission clunks, especially when hot, especially around 25mph. Reading this forum shows me this is a common problem.
Unfortunately I don't see a known fix, except to take a risk and buy a new solenoid pack. Those cost $600, so I'm not willing to roll the dice without better information.
Does anyone here know enough about the E40D to tell me if I should just accept that the E40D wasn't meant to thrive beyond 200k?
Or should I fix the thing, and if so, do you know how? (I'll post a separate thread about how to fix it ideas.)
Thanks!

The design life for the E4OD was 250,000 miles.

355k on my '96 e4od behind a 351W. Mobil 1 ATF changes and been good to go. I realize I'm lucky. I thought it was dying 100k miles ago when I swapped in a mild built engine and a few shifts flared under wot, but hasn't done that in years.
What do you mean the trans clunks?

I am not saying there are not auto trans that go farther than 200K. The E4OD in my Bronco had 235K on it when I pulled it out for a ZF5 but it still worked good. What I am saying is all bets are off after you get past 200K for any trans.

First thing with these is to read codes. First thing to read codes is to determine if you are OBD I or OBD II.
(Google "OBD" if you don't know what it is)
Code reading differs between the two.
From what I read, you should be OBD II.
Don't start taking things apart until you do this.

As a Mercedes technician for over 35 years and was trained not to replace, but fix their transmissions, I know of many that will go at least 300k. Like all transmissions, it depends on servicing. German car owners have a tendency to take car of their cars better than American car owners.

That is a weak link on that transmission and I fix them at about $700. Fortunately, reverse is the first clutch in the transmission and it takes about an hour once the transmission is out. The complete job takes about 4-5 hours.
99.9% of all shops put a used transmission in or rebuild the entire unit. The only thing that wears out is the reverse clutch. Why just the last years of that transmission? I do not know. None of the early units were like that. Putting in a used one is not a great idea, because the reverse is probably worn out.
