Strange E4OD Issue

While low speed cruising 15-20 MPH, if I step on it, 90% of the time the truck will shift into 2nd with the TC locked and really lug down. This especially happens when going around a corner then punching it. Sometimes it will realize I have it floored then downshift. But not always. Other than this issue the tranny seems to operate just fine.

Question # 2: How can I tell if someone before me has installed a shift kit? The TC will lock up after 1-2 shift. You can feel it and see it on the tach. Also the 1-2 and 2-3 shifts are very hard under WOT. Is this normal?

Question # 3: Do your guy's trucks seem to run a lot better when cold? Mine seems to have more power and different shifting points...

Do you have a chip/tuner on your truck?

You need to add your mods to your sig. You might get a tugger kit and add the parts to the valve body so all the shifts are the same all the time.

Okay. How about being able to tell if it already has a shift kit in it? When your stock tranny's shift can you feel the TC lock up? Also how about my question regarding colder operating temps. Anyone experienced this too?

Re: Strange E4OD Issue

How cold we talkin? It's snowing as we speak and abount 15 deg. F with a windchill of around zero up here.

What do you have for a truck? Any info?

EVERY diesel truck has power/trans "problems" when cold... Your injectors are actuated by oil and when it's cold the oil is thicker than molasses in January. It takes time for it to heat up.

The trans is the same way. It wants to warm the engine up first by locking the TC and engaging direct drive within the trans.

What you're experiencing is normal as far as cold weather operation as far as I'm concerned...
