Possible J-Gate problem with 2nd gear
#1
![Default](/forum/images/icons/icon1.gif)
Hi all,
I noticed an issue manually selecting 2nd gear when test driving my STR (I bought it about two months ago). Namely, I can't select 2nd at any time - the "2" indicator does not light up (all the other positions light up appropriately), and the transmission does not hold or downshift to 2nd gear. I have tried to select 2nd while parked, driving slowly, driving more quickly (30-40mph), sport mode, non-sport mode, and nothing has worked so far. The transmission itself is 100% fine as far as I can tell - shifts are smooth, downshifts are timely, and when left in "Drive" 2nd gear is used just as it normally should be. The only problem is I can't seem to manually select it. Is there something I'm missing, or is there a switch that may have gone bad?
Thanks in advance,
Ben

I have not - should I be specifically looking at the two bolts that I've read about that seem to loosen up on some people (or fall out!), or does the entire linkage bear inspecting?
Additionally, the detents or "stops" seem pretty vague to me - to the point that it's really hard to know which gear I've selected without looking. Does that also point to the linkage, or is that a different issue?

Hey all,
I'm reviving this nearly four year old post as I still have the problem described in the original post; everything remains exactly the same as I described originally. As suggested I checked the bolts and linkages (years ago) - everything was 100%.
As part of installing the rear-seat entertainment system awhile back, I had the covers off the center console area and I noted the linkage does not physically move when selecting gears 2-3-4. The linkage moves when selecting P, R, N, D, and 5, however moving from 5-4 or between 4, 3 and 2 results in no movement of the physical linkage. Please note 4 and 3 are selectable and work normally for me so this is presumably working as designed. A circular switch looking thing does turn as a result of the shifter movement, so I am guessing 4-3-2 are selected electronically once the linkage is physically moved over to the J-gate side of the shifter. This might imply the switch is broken for the '2' position, but I'm just guessing. Can any of the Jaguar techs chime in as to whether they have seen this before or what the fault may be?
I have (free) access to an indy shop with a Mongoose so I can play around with settings and flashing all I want. So if there's anything to check in the computers, please mention that as well.
I found this post with a related problem - this person was unable to select any of the electronically selected gears, i.e. 2-3-4: https://www.jaguarforums.com/forum/s...smooth-104031/
Thanks,
Ben

tbird,
The cable does not physically move when selecting gears 2-3-4. Absolutely everything aside from gear 2, including electronically selected gears 3 and 4, have worked 100% reliably for over four years. Therefore I cannot suspect the shift cable, as something else would have gone wrong in that amount of time.
Thanks,
Ben

I'm really not trying to be rude - but please read what I post; I try to state things clearly and concisely for good reason. Copied from my initial revival post is a sentence below. The bolts in question are the 8mm bolts on the transmission end of the linkage as suggested to me originally four years ago.
"As suggested I checked the bolts and linkages (years ago) - everything was 100%. "

What puzzles me the most is this doesn't seem to be a common issue at all; there are lots of posts about linkage problems but only the one I mentioned about selecting 2-3-4. The switch may be largely reliable and I'm just unlucky, leading to a dearth of information; who knows? I suppose if I don't find any other info I can ask my indie how much to replace the rotating switch.
Thanks,
Ben

Gavhowe,
Best of luck resolving your issue.
All,
To provide a kind-of-update, my indy looked at the problem, reviewed information available via Jaguar and IATN, and recommended replacing the circuit board below the shifter which sends the electronic (i.e. non-linkage) commands to the transmission. It was going to cost a few hundred dollars and I declined the repair for now. Some days it would be fun to have 2nd manually selectable, but I'm not so flush with cash that it's worth it right now.
