Well this is my first post so here gos.. I have a 94 f150 4x4 with a 351w matched with a E4od trans.. Recently it developed a shudder in 3rd and overdrive.. The odd thing is it only shudders when the torque converter is trying to lock up.. But it will lock up and it wont shudder if its not under any load.. I pulled the codes and 628 code and the fluid is a nice red and not burnt.. Just need some input. Is this a common problem with the e4od?

well if the converter is slipping there is no way that i know of to stop it, short of replacement.

That's what I figured the tranny doesn't leak anywhere.. But I figured with 190k on it doesn't help her none. How much does a new one cost?

$200-$600 depends on what your looking for. stock im assuming so figure 200-350 + labor.

I have a 2 post lift I can use. I'm just curious to why would it slip? Like what's making it slip and shudder?

just age, they wear out, the one in my 150 started going at like 94k miles.

Dang.. Is it bad on the clutches in the transmission?

Mine does the same thing, the locking converters have that issue especially when they have been subjected to poor maintenance and/or excessive towing...I got a replacement standing by but I don't tow a whole lot anymore, so Ill just wait till she dies then swap it out.

Yeah I was gonna put a new one in but I'm thinkin about a 5 speed manual swap.

Only thing I wonder does a torque converter lock up in 3rd? Because it shudders not as bad but it shudders in 3rd.
