Your welcome and yea, the all important solenoid pack, I see I left that out of my short list!

Manual lever position sensor, on the side of the trans where the shift linkage connects, tells the computer what the driver selects.

Manual Lever Position Sensor. It is a sensor on the driver side of the transmission. That is what tells the PCM what "gear" the transmission selector is in.

Do you know which wires hook together on the O2 Sensor? I have a 96 F350 with the 5.8l and the wires were ripped off at the plug. I have 4 wires coming from the Sensor. A black and 2 white and another wire that I'm cleaning to figure out the color. The wires where the plug was are Orange, Gray/light Blue, Black, Purple/Orange. Any help will be appreciated!!

If the fourth wire is gray then you may find this helpful:

All Bosch 4-wire sensors have a black wire for the signal, a gray wire for ground and 2 white wires for the heater.

Reference this diagram for the functions of each wire at the connector:

So, make sure I have this correct... the Orange and Gray/Light Blue wires go to the heater (White) wires. Black in the harness to Gray on sensor and Purple/Orange wire in the harness to Black on the Sensor.......

Orange= O2 Signal = Black wire on O2 sensor
Gray/Light Blue= O2 Signal Return/Ground = Gray wire on O2 sensor

Purple/Orange= O2 Heater supply Voltage = White wire on O2 sensor
Black= O2 Heater Ground = White wire on O2 sensor
