89 F150 E4OD not shifting past 2nd.

Recently replaced the torque convertor and filter. I can get it to move in drive and reverse but it likes to kick when it shifts into one or the other from neutral. No additional gas required to make it move it will kick in and move like it always has at 2mph idling at 600rpm smooth. When I take it on the road I have to get it up to 4k and about 30-35mph before it will shift into 2nd and it will never shift to 3rd. It's a smooth shift from 1st to 2nd silky smooth at 4000 rpm. It drops back down to 1st smooth enough too when accelerating but when slowing down it does not like to downshift on its own until it's at a full stop. I've started by disconnecting the battery to reset the computer will see if that helps in the morning.

1 step forward and 2 steps back.

I put the battery back on this morning disconnected the TV cable and gave it another shot and now it wouldnt even leave first gear. Going to adjust the TV once again and cross my fingers. I'm starting to fear it's shot. Power braked it and definitely putting a load on it. The torque convertor isn't slipping and when I give it gas and it moves faster than it ever has in first gear.

You must mean AOD not E4OD.

Hmm...

Well AOD yes but for this particular transmission its Electronic 4speed AOD haynes and chiltons just reference it as E4OD to seperate it from the non-electronic "AOD". Figure this would make it easier to find as I can't find much for diagnosis with this particular issue and the computer isn't coughing up any codes. All I get is code 11. EEC-IV if that helps.

I am thourghly confused then.

The E4od is large electronic funky shapped pan, huge trans, with NO tv cable.
The AOD has a TV cable and is absolutely not electronic
and the AODE/4R70W is full electronic but does not have TV cable.

So, before we proceed, we best find out what you are working on

As for that, we will start with you have no 3rd or Overdrive and the 1-2 shift happens at 4K.

I would say replace the VSS and the MLPS sensors as a shotgun approach to the solution. Both could cause this issue. If it is a truck, start with the VSS sensor on the real axel first. make sure to adjust the MLPS correctly if you install a new one (line the marks in Nuetral).

Oh...and you said 89 F150 in the title, so the only options you have are electronic E4od and the AOD with TV cable.

Both are easy to distinguis. The E4 will have electronic OD delet on the shift colum, and the AOD will have 1/D/OD on the column with no option for OD delete.

Prior to '92, OD switch was on RH instrument cluster

Ok the book wasn't 100% clear on that portion it labels it E4OD with a TV cable but we will go with AOD as the steering column is OD/D/1. I'm back to shifting 1st to 2nd smooth as silk at 1500-2500 rpm depending on acceleration. So smooth that you couldnt even tell it shifted unless ya manually dropped it down. That was the cable out of adjustment. However still no 3rd of OD.

3rd gear working but not right...

January 9 2007, 1:24 PM 

1-2 25mph ~3000rpm
2-3 45mph ~3000rpm
3-4 Never happens....

When it tries to shift into OD it just kicks into neutral. Pushed it to about 4500 and slowed to about 40 before I manually shifted back into 3rd. And upon stopping the engine stalls because the transmission won't disengage. To really make it fun fluid is everywhere on the passenger side of the engine compartment (to be expected since it was a little overfilled).

I checked the sensor in the rearend looked for broken wire maybe it's been off road a time or 2. Found a corroded connector in the mix but that was all.

Open to any suggestions at this point. Including pushing it off a cliff.

I'm guessing stuck valve at this point on the OD as it was out before the new torque converter was installed. As for the odd shifting TV cable still isnt 100% right even by the book but I can tinker with it later.

All working now but still no OD

January 9 2007, 3:04 PM 

Everything seems to be in running order. Still kicks a little when shifting between any gear but its shifting at 2500 in all gears except OD which still gets stuck in neutral trying to upshift and cant get it back out without switching to regular drive or coming to a complete stop.

By the sound of that you have an AOD transmission.

No electronics.

The throttle pressure seems too high.

Would explain the shifting a little rough but not completely shifting into overdrive is a new one to me. Going from 4th to 3rd was giving me trouble in the past. Going from 4th to 3rd it would wrap the engine before engaging. Then one day it moves to shift 3rd to 4th and then nothing engine winds up but never engages and been that way ever since. Limped it around in D until the torque convertor finally gave out. Figure when it was the cause of my problem to begin with but here it is with a new one in it still refusing to shift. Not the TV on this one because 3rd disengages and 4th never engages and it just coasts until it reaches a speed it decides to kick back into 3rd.


New trans time or is there still hope without scattering it all over the shop?

Your AOD is either very gummy vb or servos and possibly even governor.

but my bet is that it is time for a rebuild. The AOD and trucks never agreed with each other in stock form.

You are spouting the classic signs of OD band failure and even possible dirrect clutch failure.

However, I was able to once resurect an AOD by cleaning the vb up and the servo's to get it by - but not for long.
