Buick Enclave 2009 CXL AWD notice shudder while accelerating on an incline and also while trying to overtake on highway, RPM's jump from 2k to 3.5k.

This should help with the shutter, although you may want to change out the existing fluid if you have not done so already.It may help with RPMs, however with modern transmissions they are all computer controlled, and merging while accelerating will drop a gear for more power at higher rpm.

I would not flush, only full drain and replace. The lubegard might help. It won't hurt. I had torque converter problems with my Contour where the OD light would blink and the trans would shift hard. The lubegard helped extend the life a bit. I would recommend having a transmission tech scan the transmission for any codes and search online for any other owners who have a similar make and model.

While excellerating the rpm's will increase like you have posted. If the transmission is slipping, the rpm's will increase. Is the vehicle speed increasing as the rpm's increase?

I got about 1-2 mpg extra on the performance tune... with a gentle right foot. Heavy right foot... not so much of a gain!

A slight whistle/"sucking" sound as it draws in air but that is the nature will all of intakes. The custom intake on my 2013 STI does this as well as the prototype intake on my 2015 STI. Will add this, if you are looking for a gain in HP or MPG these two things can only be accomplished with a tune of some type. Most people don't realize changing to a non OEM intake alters the AFR that the car's ECU comes programmed to work effectively on. The $800+ "tuner" that is out there for the Tundra is BS and a waste of money, I tested it when it was released and showed zero real world gain of any kind.

If you have your radio off and dead silence in the vehicle you can hear a slight whistle while cruising at highway speeds. When you get on the gas hard you get a nice v8 throttly sound almost like you have exhaust.

I have an 09 f150 with the 5.4. I've got the Edge CTS, a K&N CAI, throttle body spacer, and custom exhaust. If I drive with a light foot I see anywhere from 15-17 city and I've gotten 23 hwy with it set to "economy." On the hwy though, anything above about 70 MPH and you won't see that good. I did tow a 4 place Seadoo trailer from CA to Utah and was getting 19 mpg using the "towing" program. The programmer is compatible with the K&N intake. When you run the setup you can select between a couple different CAI's and it will configure the tune for it. Overall I'm pretty happy with it and seen 3-4 mpg increase on both city and hwy. Hope that helps.

Non existent as far as I've experienced. It's currently in a 07 buick rendezvous with factory shocks so that's not that much suspension underneath. It really clamps well the the head rest so sway is basically non existent. Hope that helps :)

my average went from 9.0 to 9.5 but im pretty sure the reason behind the 0.5 jump is that im driving it harder now because i love the sound the intake makes at higher rpm

R.W.Hard to tell without doing some tests which are on the Vette Forum that I sent you thesite on. Just looked and if it's not you asking about this problem on there it sounds like it. If you like to gambleyou could change it to rule it out.Check this site out also for more info.http://www.aa1car.com/library/idle_speed_control_valve.htmGoodLuck,Wally MacD

Picked one up today and it does the same thing. They should at least mention it in the manual. I wasn't sure if it was normal. Apparently it is. Thanks for bringing this up and thanks for your follow up.

It sounds like a shift senoloid problem but I'm not sure if this the right one for your year or for a THIRD gear problem. I had a 02 focus which wouldn't shift properly until I turned the overdrive off. I went to advanced auto and they plugged in their diagnostic tool and gave me the code. You want to make sure you get the correct selonoid since there are 4 or five of them. I got the part and dropped the pan to install it and all is well. If you get the code and the correct part you should be good to go. Good luck.

I am having the same problem and it is driving me nuts. It is on my iPhone and 4g iPod and I have a lexus is 250 so it isnt because my products are old. I get a whirring sound whenever my car accelerates, So I am assuming this feedback is caused by the cigarette lighter. Now if there were a way to filter out the feedback

When you initially step on the pedal you will hear the intake sucking in air. The tone of your exhuast will be much deeper under all driving conditions, much like putting a four barrel carb on an old carbureted vehichle.

Sounds more like you have a bad alternator. Advance auto should be able to test it for free or which ever auto store you have

Mine did the same thing twice after I hit a large bump or dip in the road pretty hard. Made it feel like I had a bad tie rod but it was the center bracket resting on the drag link. I tightened it up made sure the bracket was tight against the differential and I am more careful when driving. It hasn't happen again.

I would contact the maker but I can guess its for Liability reasons lik a stall and crash or because they can't say it's OK for that use due to lack of required certificaion as a matter of safety. I herd good things so got them for a 4 cylinder Scion XB and the idle is rougher than I am used to. So I can't say I'll be considering them in the future.

Ours airs up 195/75 R14 tires on our old buick in about 2 minutes per tire. It runs off the battery charger so I don't know why you have a 20 minute time limit

I'm not a mechanic but likely , yes. That's what happened to me but around 40mph. I pressed the OD button to turn off OD and she went back into gear. Really easy job to do!
