Like no codes at all or did you get system pass code 11 for the KOEO, KOER tests and Stored Codes?

That appears to eliminate the transfer case or rear axle as the root cause.

Yeah the 4R100 is derived from the E4OD but didn't even exist until 1998 and none were made with the SBF bolt pattern, so NOT the same.

And you would be wasting your time. The MLPS cannot cause this to happen. No matter what happens with the MLPS the trans will go into gear when you move the shift lever.

It appears that it does go into gear. The MLPS can cause a false neutral. I was trying to rule out it was actually working. Your saying that isn’t possible. I would say that the forward clutch is bad but reverse doesn’t use that clutch so what does one of the trans engineers say broke?

No, it cannot cause a false neutral. As I said above, no matter what the MLPS is doing the trans will go into gear.

I understand that. I'm telling you that if it isn't working it will NOT cause this problem. It doesn't matter to this problem if it works or not. So testing it is a waste of time.

It could be loose feedbolts. It could be a bad pump. It could be a loose/missing internal filter. It could be a failed planetary assembly. It could be a few other things that I haven't thought of.
