Part Information 2001 Jimmy

[Jared22]

I have a 2001 GMC Jimmy. It is an automatic with a floor shift. I have been having problems with the button the the shift lever not pressing in. I took the center counsel apart to find some kind of switch with a Solenoid on the bottom of the shift lever that has a short in it. The solenoid pops out when the car is in park which allows the button to be pushed so you can shift into gear however the button still locks in without this switch if the break is not pressed in. I have not been able to find any information about this switch on what it does, what it is called or what it costs. There is a manual lever on the switch that pulls out the solenoid that I have taped down so I can use the car but I can't find anything that is affected by doing this. Can someone please help with this parts name and what it does.

 

Thanks,

Jared

What it does is it aggravates the hell out of mechanics & DIY'ers alike, & makes them question future GM purchases ...

 

 

 

Sorry I don't have any useful info for you. Sounds like that button is probably tied in with the brake switch to prevent shifting into gear without having brake pedal pressed - safety feature.

That's what is getting me as the break switch safety feature is still working fine. If my foot is not on the break I cannot press the button in even with the manual lever taped down so if it is a safety feature I am not sure what it is saving me from.

Automatic Transmission Shift Lock Control Description and Operation

Automatic Transmission Shift Lock Control System

The automatic transmission shift lock control is a safety device that prevents an inadvertent shift out of PARK when the ignition is ON. 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

• The park/neutral position switch

 

With the ignition in the ON position, battery positive voltage is supplied to the park/neutral position switch. When the transmission is in the PARK position the contacts in the park/neutral position switch are closed. This allows current to flow through the switch to the automatic transmission shift lock control switch. The circuit continues through the normally-closed 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, mechanically locking the shift linkage in the PARK position. When the driver presses the brake pedal the contacts in the automatic transmission shift lock control switch open, causing the automatic transmission shift lock control solenoid to de-energize. This allows the shift lever to move from the PARK position.

 

 

 

Park Lock Solenoid (Floor Shift Only)

 

The park lock solenoid is a safety device that prevents an inadvertent shift out of PARK when the ignition is OFF. The Ignition must be ON to release the park lock solenoid.

 

With the ignition OFF, the park lock solenoid mechanically locks the shift lever in the park position. When the ignition is turned ON, power is supplied to the permanently grounded park lock solenoid. This energizes the solenoid and releases the shift lever.

Thanks, that sound right I think. I guess I will try to shift the car when the power is off and see if it works. If that is the only thing it does I guess I will leave it taped down as I still can't find the part online even with this information.

It's probably a dealer only part. I wouldn't be surprised....
