THE AUTOMATIC TRANSMISSION WAS BEING SERVICED
SOURCE: automatic transmission is stuck in 2nd gear (limp mode)
most newer vehicles have transmission control modules,that go to a default of 2nd or 3rd gear when they go bad! I had a 91 plymouth stuck in 3rd gear because of this module! could be your problem! when mine went out, it smelled like something electrical burned inside the the passenger cabin! I would check all the electrical connections on the transmission first good luck

Ok ready to stand on your head under the dash?
It's doable... there is a flange connected to the gearshift lever under the steering column. If you remove the lower dash cover where the fuses are, you should be able to see it when you move the gear shift lever... look around on the floor of the truck to see if you dropped a star-headed bolt or two... these bolts worked loose on my superduty and made shifting very difficult..it was an easy fix... let me know how you do on it.

try having the transmission filter and fluid changed.

hi have a 2000 2l 156 selespeed problem with gearbox is light comes on dash and gears won't select have replaced the gearbox pump at great expense but has now stopped working again can any one advise if this could be other issue

it is eletical eather a fuse is blown or the speed sensor didnt get hooked up dose spedo work

The IPC detects a loss of serial data communications with the ECM.
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
?€¢
The automatic transmission shift lock control solenoid
?€¢
The automatic transmission shift lock control switch
With the ignition in the ON position, voltage is supplied to automatic transmission shift lock control switch. Voltage flows through the normally closed contacts of the automatic transmission shift lock control switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid causing the transmission shift lever to be physically locked in the PARK position. When the brake pedal is pressed the contacts in the automatic transmission shift lock control switch open, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to be move out of the PARK position.
The transmission range (TR) switch is part of the park/neutral position (PNP) and backup lamp switch assembly, which is externally mounted on the transmission manual shaft. The TR switch contains four internal switches that indicate the transmission gear range selector lever position. The PCM supplies ignition voltage to each switch circuit. As the gear range selector lever is moved, the state of each switch may change, causing the circuit to open or close. An open circuit or switch indicates a high voltage signal. A closed circuit or switch indicates a low voltage signal. The PCM detects the selected gear range by deciphering the combination of the voltage signals. The PCM compares the actual voltage combination of the switch signals to a TR switch combination chart stored in memory.
You need a Tech2 scan tool to diagnose this problem ! possible range sensor !
