Yes it is. There was bulletin issued. Finding a Motorcraft replacement is tough these days. I believe Standard Motor Products still makes them and includes the new connector and instructions.

Update

Once in a blue moon it will fail to go from 2nd to 3rd, but unhooking the battery for 1 min seems to bring it back.

Wish I could grab a MPLS mentioned above. Oh well, maybe someone can benefit from this thread.

Codes are the true teller of this. Nothing will be smarter and know more then the computer telling it what to do.

My understanding is that a faulty MPLS can't set codes. Not saying this as a fact.

The store won’t sell the part to you?

Sort of. Mark Kovalsky has said in the past that the MLPS can cause false neutral problems but not set a code.

I'm not even concerned about the MLPS.

Just what is actually going on with, & what the ECU is seeing or thinks its seeing.

Yah know, minor ****

Out of stock everywhere I look.

As for the codes, I didn't grab them as I was trying to get back on the road. It will happen again and I'll grab them then. When I'm not on the side of the road.

For now finding a new/good condition MLPS is my next step.

That's a good way to pretend you're fixing it, when all you are really doing is wasting time and money. If you don't have the codes, you don't know what is wrong.

It is possible for a bad MLPS (now called a TRS) to cause a false neutral at highway speeds and not set a code. Most failure modes of the sensor WILL set codes.
I can't come up with a way the MLPS (or TRS) could fail that could cause your problem.

The ‘94 Bronco would do this..

as in you’re driving along and the transmission acts like it is in neutral and then bangs as it goes back into gear.

So you don't really understand how diagnostic codes work?

They are stored in memory for retrieval later without the need for an issue actively occurring or a check engine light being illuminated.

If you don't have codes or a pass code, that says something too.

But hey, you seem to know best.

Pulling the codes when you're not in a good situation? Yeah no.

Thank you to those who have lent help in a respectful manner. I and others appreciate it, you have no idea how much!

It will certainly happen again no big deal.
I'll get the codes when I'm in a better location/situation.

Love the E4OD just not its management system.
