Ok, here is my dilemma.

This vehicle is my fiance's car, and formerly my grandmother's car. The transmission has had no prior issues, whatsoever. It's been a great car.

We replaced the transmission range sensor (autozone referred to it as a Neutral Safety Sensor, but Haynes referrs to it as TRS). It was so rusted on, that we had to dremmel it off carefully. After putting the part back on, and ensuring the neutral line matched up to the linkage and everything, we took it for a drive only to find out that now it doesn't shift through the gears in drive (2nd, 3rd, 4th, overdrive, nothing). Letting off the gas does nothing. It feels like it isn't in gear all the way, despite our supposed "proper" alignment.

The sensor was replaced because of the infamous symptoms: Power steering assist intermittently engaging and disengaging, seatbelt light coming on, windows not rolling up or down, radio cutting out and staying out most of the time. All of these only happened when the transmission was in "Drive" or "Reverse". In "Park" or "Neutral" the car behaved normally. This was a classic case according to this forum.

So we fixed all of those problems with the replacement sensor, now the transmission wont shift out of 1st while in drive, drive with overdrive, etc. It almost feels like it wants to at about 2500-3000 RPMS but something isn't right? Sometimes it doesn't feel like it wants to shift at all. It never does.

What could cause this problem? We do have a check engine light on.
Again, the transmission was perfect until we replaced this sensor, it is hard to believe that it decided to crap out coincidentally directly upon replacement.

What is our problem?

Bits of info:
We forgot to remove the negative terminal on the battery before working on it. Could this confuse the computer?

Mechanics say the shift problem has nothing to do with the TRS/Neutral Safety Switch, but google and ford forums say otherwise. Must be a ford thing?

Are you sure it's aligned right? It tells the computer where the lever is... Put er in drive and see if you can go above 4000 rpm if you can't then your sensor is misaligned and your car thinks it should be in park or neutral...

There are two different ones depending on the transmission. The AX4S uses a 8 pin one and the AX4N uses a 12 pin one. Connectors are different so you should not be able to plug it in to the wrong one.

Otherwise it would be alignment.


Shift Control Linkage

The transmission shift linkage adjustments must be performed in the order in which they appear.


Column Shift

1. Place transaxle range selector lever in (D) (OVERDRIVE) position or D (DRIVE) position on vehicles equipped with a transmission control switch (TCS). A weight of 1.4 kg (3 lb) should be hung on the transaxle range selector lever to ensure the lever is located firmly on the (D) (OVERDRIVE) or D (DRIVE) position on vehicles equipped with a transmission control switch (TCS) detent.

2. Loosen manual control lever-to-control cable retaining nut.

3. Move transaxle manual control lever to OVERDRIVE position or D (DRIVE) position on vehicles equipped with a transmission control switch (TCS), second detent from most rearward position.

4. Tighten retaining nut to 17-23 Nm (13-17 lb-ft). Check operation of transaxle in each transmission range position. Make sure that park mechanism and transmission range (TR) sensor are functioning properly.


Floor Shift

1. Position transaxle range selector lever in DRIVE position against rearward stop. The floor transaxle range selector lever must be held in the rearward position using a constant force of 1.4 kg (3 lb) while linkage is being adjusted.

2. Loosen manual control lever-to-control cable retaining nut.

3. Move transaxle manual control lever to DRIVE position, second detent from most rearward position.

4. Tighten retaining nut to 17-23 Nm (13-17 lb-ft).

5. Check operation of transaxle in each transmission range position. Make sure that park mechanism and transmission range (TR) sensor are functioning properly.

The part itself was cracked so malfunctioning. The computer thought the car was in reverse when the trans thought it was in everyboosituon, so it didn't shift. Be careful putting on the part. Also don't buy autozone parts they're cheap
