Driiving with the j gate
Okay, so i have the jaguar x type, automatic, but its has 2,3,4 on the on side, now how do i drive manually, and shift into the next gear. I have driven in second, third, and fourth but i always think that i have to pull over and switch so i don't grind gears , can anyone give me tips on how, and when to do this, i like regualr drive but i want to get more out of my car. and is it okay when i'm in 4rth, and i just go over to drive or should i stop then shift to drive, not that i have.

You don't really select a gear when you J-Gate, you simply prevent your transmission from going over the selected gear.
So you can start in 2, and when your feel you're ready to shift higher just go to 3, and so on. After 4 you can move to D so that it shifts to 5th gear. When you need to slow down you can move back to 4, 3 and 2 so that your engine slows your car down instead of having to use your breaks.

Yea I start in 2 when going from a stop. Remember that the car will rev through first gear first, then 2nd. So don't shift to 3 till you are in 2nd gear and want to change up to 3rd. I hate that Jaguar doesn't let you select first gear. My bimmer does and that is nice. In the jag with my foot planted, the car will only rev till about 6300-6500 in first. It won't go all teh way to redline.
I move it between 4 and 5 (D) all the time while cruising. You won't hurt the tranny. I only move it over to 5 though if I'm cruising at 50+ mph. Under that I leave it in 4 otherwise the car is so sluggish.
When downshifting, for either passing or engine braking to a stop, I find that blipping the accelerator between shifts lets you rev match the shifts perfectly so the car doesn't jerk at all. This takes some time to get used to. You might blip the gas too early and the car will still be in the higher gear or you might blip it too late and car will already be in the lower gear. Then the car will lurch forward. But if you get it perfect, there will be no jerk on downshifts. Not to mention it just sounds amazing.

Normally I shift about 4000rpm. Usually I get stuck behind people in a kia who take an hour to accelerate to the speed limit so redlining is useless.
And another cheating method to shift is when you have your foot to the floor in 2nd, you can shift the lever to 3rd, but the car will not shift up till it hits redline. But this also prevents you from bouncing off the rev limiter. So it's not like a true manual in its shifts, but its still fun.
And you have a 3.0. The 2.5's are so slow that I lose to some new 4-cylinder camrys and such at stoplights.

Performance wise, I think with the car in D + Sport mode on, its similar to j-gate. All that j-gate does is simply hold the gear you select. It will not shift up at redline like some other cars. So for example you leave it in 3 and ur accelerating, but then you need to brake or lift off the gas for a second before accelerating again. This is where J-gate helps because the car stays in 3. If you left it in D and the car was in 3rd gear, as soon as you lifted off the gas, the car would shift to 4. Then when you get back on the gas a second later, you have to press harder so the car shifts back down to 3.
And whenever I use j-gate, the car always uses more gas. Like I get 11-14 mpg. Granted I drive my car really hard because it is a slow car. When I leave it in D I get about 17-18 mpg city and 28mpg highway.

ez53436, I wouldn't say that you are necessarily hurting the tranny, but, depending on where you shift at, you can make it a lot harder on the transfer case. really, if you use the gas pedal in certain ways, you can make the car shift where you want (ie, press on the gas hard to get going, ease up when you are near the shift point and it will normally shift to the next higher gear). The only time that I use the J-Gate gears is when I am wanting high RPMs and not a lot of speed (ie, right after doing a flush with Seafoam). Other than that, you may find it useful when in bad weather as this can help prevent with wheel slippage. I also seem to remember that if you start in say 3rd gear, the tranny is actually in 3rd gear and in slippery conditions, this can make for better traction as the tranny is slipping and you aren't getting any surges in the driveline which can lead to loss of traction.

Thermo, thanks for your reply. I wasn't planning on simply using the J-Gate to shift at high RPMs. The main reason I want to use it is just because I'd rather control how high of a gear it goes up to. I would normally shift around 2,500 - 3,000 RPM. I assume that shouldn't hurt the tranny any?
