MLPS Questions

I'm putting an E4OD/4R100 in my '53 f100. I got a used trans that is supposed to be a '94 E4OD, but I think that it's a '95 or later 4R100.

It had a broken MLPS, so I got a used analog MLPS and installed on my transmission shift lever. Then I measured the resistance from the Light Blue to the Gray wire, while I shift the trans.

Park = 4, 180 Ohms

Reverse = 1, 447 Ohms

Neutral = 734 Ohms

Drive = 401 Ohms

2nd = 401 Ohms

1st = 86.7 Ohms.

Is this MLPS defective?

Is the shift pattern the same on a 4R100 as an E4OD?

I am going to use a Bauman Optishift controller, so I can use the analog MLPS.

The first 4R100 was in 1999. The easy way to tell if you have and E4OD or a 4R100 is that the 4R100 has two speed sensors on top of the trans, while the E4OD doesn't have any.

No two positions in the MLPS will have the same resistance. Something is wrong there.

Neither the E4OD not the 4R100 have shift patterns. Shift patterns are located in the computer, not in the transmission.

I have a speed sensor on the top of the extension housing. There is a reluctor wheel on the output shaft. There is no speed sensor on the trans.

The trans has the later solenoid connector.

I meant the shift selector positions. Does the 4R100 have 7 positions, the extra being OD?

That's an E4OD, not a 4R100.

The E4OD and 4R100 both have 6 positions. P, R, N, OD, 2, 1.

I'll take the MLPS off my 83 F100. That has a small block with an E4OD. I'll swap that one into the new trans, and check the resistance.

OK, the MLPS is OK. The resistance readings are:

Park = 4, 180 Ohms

Reverse = 1, 447 Ohms

Neutral = 734 Ohms

Drive = 401 Ohms

2nd = 230 Ohms

1st = 86.7 Ohms.

My next question is:

What is the bolt diameter & thread pitch for the transmission mount to transmission bolts? Are they Metric or US threads?
