Rebuilt E4OD slipping at 2-3 shift and TC locking up really hard sometimes

I've noticed since I've had my E4OD transmission rebuilt (in a 95 PSD E series Van) That the shifts flare once in a while and other times it'll actually slip quite a bit mostly on the 2-3 shift. And I mean BAD slips.

It's basically a slip from 2-3 --> RPM's shoot way up --> grabs for a second then starts slipping again and the process repeats for around 5 seconds until it finally grabs into third and holds.

The other thing I've noticed is that the transfer of the torque to the back wheels is not quite as good as it was before the rebuild. Things seem not as firm sort of like the engine is spinning but not having the grip that it used to before the rebuild.

The last thing I'm not happy about is that sometimes the TC lockup really slams. I think what is happening is the #4 gear and TC lockup are happening at the same time at around 45MPH which is really lugging the engine. The TC is never locked in 3rd gear even with OD off and at 45-50 MPH. I checked this by lightly pressing the brake pedal while driving (foot on the gas).


The WORST part about this is that it only happens sometimes so diagnosing may be sketchy (right now the van is back with the guy who rebuilt it). When it happens the OD OFF light will start blinking for around 30 seconds to a minute and then go back to normal (stops blinking). There's no real rhyme or reason to when it slips. It's happened cold and it's happened hot. Today I thought I was going to loose the transmission all together it was slipping quite a bit on the 2-3. One instance was probably around 20 seconds of slip grab slip grab slip grab before it continued on. The rebuild was $1785 and less than 150 miles old so this is not encouraging in the slightest.

Any ideas what could cause this and that it only happens sometimes?


EDIT: one other thing... when I floor it when passing up hill, shifts aren't firm (downshift to 3rd), it's as soft as can be.

Since the OD light was flashing a code will be stored. That is a good starting place to start the diagnosis.

It came on during the slip. I bought one of those $100 walmart OBD-II readers a while back and it wouldn't read this vehicle (95 PSD Van). Do I need something fancy to read the code? ODBCom's laptop OBD-II to USB laptop computer scanner wouldn't tell anything either. Nothing at all. This works fine on other Ford and GM vehicles (Windstar and a few others).

The OD light started blinking during the slip. It stopped blinking around 30 seconds or so after the slip. This happened several times... slips, comes on, goes back off.

The cheap OBDII code readers can't read Ford transmission codes. You need a better one. The only one I'm familiar with is the Ford NGS.

Would this do it:
AutoEnginuity OBDII OBD2 Windows Scan Tool Scanner(USB): eBay Motors (item 300438069821 end time Jun-22-10 19:00:07 PDT)

(Auto Enginuity for around $200 on ebay)

I believe this is the hardware (usb to OBDII cable).

The cable is included in the package. You get an installation disc and the cable. But like I posted above: you will need the FORD software (extra) I believe to do the tranny codes, but it will do so much more.

The guy who rebuilt the transmission doesn't have the right reader.

Hopefully he'll be able to get it working right. I asked him before he rebuilt it if he was familiar with the E4OD and he said he should have no problem because he'd rebuilt hundreds of C6's and AX4N's and S's.

Hopefully not $1785 down the drain. Seems like he's not up on all of the electronics end of the transmission.

OUCH!!! That would have been my first warning flag. To me that's like saying "I have built a bunch of chevy S/B's so it should be no problem rebuilding your 7.3 diesel" And then not to have the proper equipment to diagnose any problems?

I too hope that he can make it right.

I feel your pain. My truck was doing the same thing between 1st and 2nd. Then it would occasionally happen between 2nd and 3rd. I bought the truck (knowing that it was going to need some fixing) from a guy that "rebuilds transmissions in diesel Mercedes - a pick up truck couldn't be too tough." Well guess what - it proved to be tougher than he thought because it only lasted about 400 miles before it crapped out. I took it by a few different shops and they all said it appeared that it needed a new transmission and some of the parts put on it were not made for HD trucks. There is a big long story that goes with the whole thing, but the quick end to it is that I had a new transmission put in by someone who knew what they were doing and warranted their work. Hope it ends well for you....

The automatic transmission speed control sensor that fits into the top of the rearend and has two wires coming out of it will cause this problem routinely. It costs about $30 and the connector plug about the same and takes about 30 minutes to replace, always replace both and always solder the connections is an absolute must. You can also disconnect all battery cables overnight and then reconnect and start it and try it. It's going in and out of emergency shifting mode and you will ruin the transmission if you don't take these steps.

I have read quite a bit when I had my first bad E4OD in an IDI turbo truck (not good luck with these so far!). So one of the first things I replaced when I noticed the slipping was the vehicle speed sensor. But the weird thing is that the speedometer is working. Would a problem with the speed sensor let the speedometer give an accurate reading?

The only thing I did notice is that the speedo seems to wander ever so slightly at higher speeds (say above 60MPH). It'll waver a few miles per hour and I can tell it's the needle and not my actual speed.

I didn't replace the connector.

But the needle isn't acting too weird.

Wouldn't the speed sensor cause the transmission to go into limp mode and bang into gear/i.e. not the slipping I'm noticing?

My OD OFF light started blinking during the major slipping episodes but not continuously. It was just during the slipping. It'd go off 30 seconds or so after the slipping stopped.

It does seem like it could be electronics related (possibly) because there's no rhyme or reason to when it will shift nice and when it wont. All the sudden it'll just start causing all kinds of grief then I'll drive it again a few minutes later and it'll shift just fine.


Could my PCM be the problem?

It costs nothing to didconnect the batteries overnight and $30 for the part plus labor to solder a new connection. One at a time or both at once.
