If i were to fit a sport mode switch to my car (doesnt have one standard) would the loom be there for me to plug it in and make it work?

 

Don't know the answer but the switch loom would be the least of it, I'd think. I'd wonder if everything was in place at the transmission end of things !

I was thinking the box maybe the same??? Might be wrong though.

 

I have the sport mode on my X300 but I'm not quite sure what it does. Some one told me it was more than just the tranny. Something to do with electronic adjustments to the suspension (not really sure on that one).

 

I'm pretty sure you cannot fit a sport mode button. I didn't even know our cars came without the buttons, but you learn something new every day.

 

It changes the transmission shift characterisitics.

As far as I know there is no tie-in with the suspension on the X300s. On my XJR, at least, the sport switch works on the transmission only. Perhaps on later Jags.

I think the preconceived notion about the sport switch working on more than the transmission comes with other, more modern cars. The BMW M5 (although, I think it's an "M" button as opposed to a sport) even adjusts the seat's position when it's "sport" or "M" button is engaged.

 

Doug and TopHat are right - it's just the shift points on these cars, nothing else. On part throttle the transmission holds its lower gears longer and changes down more readily, and on full throttle it will hit the red line before changing up, rather than at about 4,600 rpm when it's in "Normal" mode. I tend to switch to Sport in traffic or on a busy freeway when I want instant response for lane changes, but otherwise find Normal is more than sufficient.

 

Hello
You probably have this solved by now, but here goes:
When engaged, the Normal/Sports mode switch located below the J-gate gear selector in an automatic prohibits the transmission from shifting for an additional several hundred RPM; if accelerating for a sufficient period (e.g. outrunning a an Audi from a standing start), it will wind out second and bypass third entirely.
It accomplishes this by grounding an output on the power control module, which re-configures the shifting profile.
In Normal, the output wire from the module is open (i.e. it goes into the switch, but no continuity is made.
In Sport, the output is connected via the switch to digital (also known as, 'signal') ground.
For this to work, you must have power control module with this feature and connect the output to a digital ground via a switch. (A simple, aftermarket toggle switch will work just fine. The stock unit is not a de-bounce; it's a run of the mill rocker switch... nothing fancy.)

Sorry to ask this about mine but someone may know the answer!!.. Ive got a 96 xjr and I have a 3 position switch!
S for sports moves the change gear point and sport on dash comes up if toggled to left.
In centre its normal mode..
and toggle right the switch lights up on dash sport but the switch has a 1 with a /though it!!!!!! Not seen in any other car but all position work it's like it has 2 sport modes!!!!

 

Your post is a little hard to follow....but the 3 position switch sounds interesting.

My '95 XJR had a 2 position switch.

The "1' with a slash through it certainly sounds like a designation for first gear being locked out. This has come up before. The service manual mentions the transmission on the XJR/6 (and V12 X300s as well) starting off in 2nd gear unless Sport mode is selected. However, this was not the case on my XJR/6 and others....which start off in 1st gear in both sport and normal mode.

Perhaps we're discovering another detail year-to-year (or market-to-market) difference in XJR/6 build specifications?

Anyone else with a 3 position switch?

The XJR should only have a 2 position switch with S and N. In normal it starts in second gear, in sport it starts in first. The 6 cylinder XJS/XJ40 has the switch with the first gear lockout, kind of a winter mode.

In this case I suspect the switch has been changed out for whatever was at hand, rather than the proper switch.

 

Well my farther in law has a 97 xjs 6 Cyl and that only has a two position switch..if mine had been replaced Ed incorrectly I would expect it to only work on two of the positions not all 3

 

Except at least one. Mine

Your car was weird. It's supposed to start in 1 in S mode. Mine does, as does my 94 XJS with the same transmission and the 6.0.

 

I can't explain it. But I'm sure that a few others have reported the same over the years so the weirdness may have a pattern of some sort.

Since my car's behavior clearly disagreed with the service manual I rationalized that the service manual was simply incorrect (which seemed plausible), and that the XJ12 was intended to start in 2nd due to the more luxurious nature of the car, and the XJR intended to start in 1st due to the more sporting nature.

The result, on my XJR, was sport mode simply raised the shift points under light and moderate throttle. At WOT the trans shifted at 5500 rpm regardless of mode selection.

So I was replacing a few things on the Ski slope and after putting it all together at first ran into a heart-stopper where my car would not start. After thinking about it figured it has to be a fuse so I found it and replaced it. However, now my sport button no longer works. I replaced F14 on driverside kick panel. Is there another one that I should be looking for?

 

Have you disconnected and reconnected the cable to the sports switch just incase its an easy fix?

 

Yea I tried that in fact I tried another switch and it does the same thing. I looked at all the different fuses and don't see anything else that may be the issue. Also does anyone know where you can get a bulb for the rocker switch

 

OK lady... Any feedback or at can tell me where to go in the manual. Cant seem to find ut
