awesome, thx. will do this week and let all ya'all know how it feels

thx jeepjeep

 

your welcome sir..

 

had 45 minutes yesterday so i tried to take out the NSS, but couldn't get it off. i got the screw out, took off the nut, but then couldn't pull the thing off. didn't have much time so i'm sure i woulda wrenched it off eventually, but is it normal for it to be tough to pull off?? do i need to get a screwdriver in behind it and wrench it out? i didn't wanna break it and didn't have much time so i just put the screw, nut, and plugged it back in. help please, thx

 

yes you need to coax it off...be carefull you can break it...easily....

what i did was take a screw driver iwth a fairly wide tip..put it behind the sensor where the linkage rod comes out of it and twist...till it pops off.

 

mine was doing the same thing, I'd get on the interstate and get up to 70mph and it would be at 3100 rpm the only temporary cure to this was while at 70 put it in Neutral, turn key to off for 5-10 seconds (do not do this in a curve as you will not have power steering while key is off) and crank it back up and put it back into drive. when i did this it would kick into OD and my RPMs return to normal 1900-2100 RPMs for 70 MPH and it stays normal until I'd put it in park and switch it off. I did this for 2 months this summer (against my will but we were barely making ends meet fiscally so there were no funds to fix it until earlier this month when it got some love!)

the cause to my problem was only the NSS HOWEVER the diagnostic codes were indicating NSS, Transmission range sensor, and both O2 sensors

mine is a 2000 2WD 4.0

 

so ,, this cable adjustment is by throttle body ? where you rev engine by hand ? gonna check it out in daylight tomorrow

also .. looking up TPS replacement, do the '93 engines need ohm adjusted ? my 90 renix does (manual trans) .. the BWD part I found online looks to be un-adjustable

this quesiton refers to '93 auto 4l .. trans is shifting like said above

1-2 takes high rpm, 2-3 is fast .. not sure if OD is kicking in, rpms seem kinda high doin 65 (no tach gauge to watch) .. park to drive has womp to it

figure i would start here .. this is my 1st auto xj .. want it running smooth for emissions .. thanks

 

93 TPS is bolt on and go. Not adjustable. Sounds like yours is bad.

Also for future reference since the NSS came up- cleaning it is only half the job. The spring-loaded contacts also lose pressure over the years. While it's apart gently stretch the springs a bit to restore contact pressure.

 

Where is the sensor located? Cus mines been doing this for 4 years. I just shut it off and wait then turn it back on and it would be fine but last weekend it went completely out. I got a complete trans from work for 75$ so ill just put that sensor in it. Any help is appreciated!!

 

My 94 stopped shifting into OD, after reading this I checked my TV cable... it was all the way out. I adjusted it and am going to take it out in a bit to see if this fixes the problem. the trans shop didn't even mention this adjustment to me. they said I needed a new vehicle speed sensor.

 

For anyone who hasn't done the NSS before... I literally just did the NSS clean for a side job having never done one before. I would recommend anyone do it. It was stupid easy. I had heard about how difficult it is to get the thing off, and that was what I was the most worried about.

When you get down there and really take a look at it, the getting it off part becomes easier. After removing the adjustment bolt, bend the lock tabs out of the way on the main nut. With the main nut off, you can see that the shaft comes through the middle, and the NSS is clamped down onto it by the nut. I simply soaked it in penetrant, screwed the nut back on just enough that it would engage the threads without clamping, put a screw driver behind the nut and used the edge of the trans pan for leverage. Popped right off. This was on a rust belt police XJ also... So if one were to stick, this would be it.

With the NSS off the trans, taking it apart and cleaning it was simple with some electric cleaner, emery cloth, and die-electric grease when putting it back together.

I would check: All these things are easily replaced/cleaned. The nss is a pain but not worth 800 bucks to get fixed imo, 9/10 you can get away with just cleaning it like previously mentioned. I would just replace the tps/speed sensor. They are cheap and go bad anyways. Avoid the headache.

1.TPS ( 30$ two torx screw on throttle body/replace)
2. Speed sensor ( on transfer case/replace )
3. NSS ( Take off and clean )
4. Adjust TV cable.

Can you get into overdrive/ Will your trans kickdown?

 

Way too much! Auto parts warehouse has nss for my 99 jeep cherokee for $135, and it is a pain to do but would be a hell of a lot cheaper than having someone else do it! I just did the three solenoids for the transmission and some places were trying to charge 230 a solenoid! Found a site that sold all 3 for a bulk price of $250, put them in myself. Its pays to look around, and to do your own work
