question on rear differential

I need an EXPLANATION !!!!

Today, I was idling the truck to keep my granddaughter (and me!) cool while my wife went into the post office.



When we went to leave, I couldn't get the truck out of park no matter how hard I pushed the brake pedal. This was on level ground and the steering wasn't in a bind.



I shut the truck off and took my foot off the brake. Started back up and it still wouldn't come out of park. I gave a harder tug, heard a snap, and these parts fell out onto the floorboard.



As far as I can tell, the only effect is that now I can pull the truck out of park without pressing the brake pedal. No heartbreak there.



Is there some other reason I need to fix this?

It suddenly occurred to me that I might have to order the part from the dealer, so I took my 6-year-old granddaughter out to help me check.



The brake lights work fine, so I doubt the switch is broken.



For what it's worth, the part on the left (in the pic) is a coil and it was hotter than a two-bit-pistol when it first fell out.



It seems that the left and top pieces form the main parts of a solenoid.



Bob
 
The only reason I know of to fix it is if your granddaughter happens to pull the lever out of park sometime.
 
That is part of the soleniod that gets powered up when you step on the brake to take it out of park.



Bob
 
The Brake Transmission Shifter Interlock (BTSI)(Brake Transmission Interlock Mechanism), is a solenoid operated system. It consists of a solenoid permanently mounted on the gearshift cable.

Heck, I personally find the "step on brake to shift from park" more annoying than anything else. I'd leave it off.

Manual transmissions don't have this sort of wacky "safety" device. "Apply brake to shift to neutral".

Thanks for all the input. I thought it was probably the interlock, although the name escaped me.



I'll have to think about whether to fix it or not. The granddaughters are NEVER EVER left in the truck with it running (or with they key in the ignition) without adult supervision, so I feel there's minimal danger there.



I've had trouble getting the shifter out of park several times. This does put an end to that problem. :cool:



If I do decide to fix it, can I just purchase the interlock, or do I need the whole cable?



Bob
 
You may not let the granddaughters in the truck unattended when it is running or with the key in the ignition but the interlock broken neither of those matter. They would still be able to take the truck out of park and if the truck in on an incline and the parking brake not set, you could have a problem. I suppose no more than us manual guys though. If you decide not to fix it just be mindful... .

It's not quite the same. My shift lever still stays locked unless you turn the key, unlocking both the steering wheel and the shift lever.



The "Brake Transmission Shifter Interlock" and the ignition lock for the steering wheel and shift lever are apparently two completely independent systems.



The bottom line is that my truck, with the broken interlock, still can't be pulled out of park without the key. :)
