Got quoted 805 bucks total for parts and labor after diagnosis waved. Factory part (called some dealerships and got quoted 394 and 380 for just the part).

Am I getting ripped off?

Thanks

1999 Jeep Cherokee, 4x4, 4.0L 6cyl

 

i've never heard of that sensor, get a part number. only thing close i can think of is the throttle position sensor, which is ~50 bucks and can be replaced in 5 minutes. whats the problem with the truck?

 

i think he is refering to the NSS switch....and if that is the case...what is the vehicle doing?

 

The Range Sensor Signal goes thru the NSS. Pull, clean, lube (dielectric grease) reinstall...and post up the results.

 

Yeah it's the NSS (called around, dealerships, etc...). got quoted 569 by a dealership for parts/labor.

My jeep is downshifting when i'm travelling. On the freeway it'll drop down to 3rd for no reason.

 

Also, while sitting at a stoplight, it'll jump up its RPMs and it'll take extra effort on the brake pedal to keep it in place.

 

Alright, I asked if they had tried just cleaning the NSS to see if it'd work and they said it was for sure coming up as defective. How can you tell if it just needs to be cleaned, or if it has for sure become a defective part?

The Jeep has just reached 100k miles.

 

They're jerking your chain Brother. Any loss in signal from a dirtycontact is going to be flagged as a defective part. Don't let them touch your rig again or you're gonna get screwed out of your hard harded cash.

Cleaning the NSS is simple DIY job.

 

I thought that the NSS, although having the pinout to do range detection, is only used for the neutral safety and reverse light feature. At least on the 93, 94 and 95s I've had. On the 94 I had the sensor unplugged at the firewall and jumpered to the neutral position for ages and OD still worked. I thought the "transmission valve cable" or whatever the heck it's called, the black cable that connects to the throttle under the hood and has an adjustment procedure, is what controls when the XJ goes from third into OD.

your talking about the TV cable.....and yes the OP should try to adjust this..it takes longer to open the hood than to adjust....however as far as i know the NSS only controlls N and p starts and reverse lights....so if it is droping gears...TV adjustment and solenoids come to mind.

This article says the NSS switch can keep the jeep from going into overdrive if defective.

Reading the repair manual and searching around it looks like the NSS switch can be defective if the continuity between the terminals isn't there. From what you guys are saying, this is not a common problem? I asked the guy straight up if he could try just cleaning the switch but he said it was for sure defective. I will ask him to tell me how he knew this.

Btw, I called around and got other quotes and got the price cut in HALF. I'm not happy that this guy thought he could jerk me around like this and I still feel like I am being taken, but I've already signed a diag paper and I'd like them just to fix my problem...

If anyone knows a good mechanic in the Phoenix/Mesa, AZ area let me know. I've had trouble finding someone I can really trust and know will treat me right.

Thanks for the help.

Any other advice on this issue is welcomed and encouraged.

 

try to adjust your TV cable......its free and easy.

 

well i got my jeep out of there. it's working fine now, so maybe they cleaned it up when they were testing it?? i really hate working with shady mechanics. if it starts up again i'll take the NSS out and clean it myself.

how would i adjust my TV cable if this starts acting up again?? i'm no jeep expert but i can follow instructions pretty well.

again - phoenix/mesa/gilbert, az mechanic referral is welcome!

 

TV Cable Adjustment



To adjust the TV cable you:
1: Push in and hold the release button
2: While holding in release button, push "conduit" in as far as it will go
3: Release button
4: Rotate throttle to WOT, some people do this with the gas pedal. Others do it from the engine compartment.
5: Hold at WOT for a few seconds, cable should ratchet out a click or two.
6: Your TV cable should now be properly adjusted, take it for a test ride.
