Why is my patriot reving at 3000 rpm's at cruising speed? Help me out here.

What is cruising speed? What tranny do you have?

I'm assuming you have the CVT2L, if so all of ours do this, there are multiple threads on this, but the short of it is the CVT2L has a higher final drive ratio which causes the RPMs to be higher then the regular CVT2, you can expect to hover right under 3k at 65MPH

GREAT CAESARS GHOST!!!!
Wont that will kill you in gas?

I average in the low 20's for my MPG. when I'm around 65MPH lately its been around 22MPG

2.4 liters,cvt freedom II trail rated....it's like i'm missin an overdrive....any software up-date for this....3000RPM's...unbeleivable.

Hey pump....Im moments away from leaving work...quickly..how fast on the highway do you have to go in order to see 3k rpm? Ill let you know how i make out when i get home

I got a 2.4 Front wheel drive CVT..

110kms/hr...in miles i don't know!!!!!

its close 68MPH right in that range I was talking about. Unfortantly CVTs don't have and "overdrive" and I have not seen a software update to compinsate for this, I wish there was. As much as I like the smooth ride in the CVT, I think the Patriot would be much better if mated to a regular tranny

Mine is the 2007 CVT 2 (not trail rated) 4x4. I drive everywhere on a 110 kph highway (70mph). The tach shows about 2400 rpm at 110, and I get 24-25 mph (US).

110kms/hr...in miles i don't know!!!!!

Ok,,,just went along the 407 from Erin Mills Prkwy and got off at the 404.
Hate to say it, but @ 110 kph, I maxed out @ 2300 rpms..averaged about 2100.

Get yourself into the dealer and ask them to fix this, before you bring on any threat of mechanical damage. Not to mention your gasoline bill.

You do not have the same transmission he does so the results are not comparitive.

CJ has the same tranny and his experiences are the same as the OP.

Okee dokey...thanks

Well, that's the reason it revs so high at that speed. The Trail Rated Patriots have a higher final drive ratio than the non-Trail Rated ones.

There was a Technical Service Bulletin (TSB) for the '07 Patriots to reprogram the engine and/or tranny electronic control modules. It applied to vehicles built before a particular date. It may be worth PumP_3A's time to get the dealer to check it out. It is in Chrysler's interest to make sure it is right to minimize their warranty costs.

The original EPA figures for the '07 trail rated 4WD with CVT2L were 21 city and 23 highway. The revised figures per the 2008 test protocol are 19 city and 21 highway. The 2008 Trail Rated Patriots are a little higher at 20 city and 22 highway. You can check the figures at this website.

FWIW and IMO and YMMV. :)

I still think down the line one of ya' will find a mechanical fix for this...either weights or springs or combination. There has to be a way to lower the rpms.

Well, that's the reason it revs so high at that speed. The Trail Rated Patriots have a higher final drive ratio than the non-Trail Rated ones.

if the trail rated had a higher final drive ratio, it would turn lower
rpms at hiway speeds. I think that the CVT2L is geared lower for
more torque resulting in higher rpms and lower gas mileage.

Taller tires might help a bit...just adjust you miles traveled to figure out mpg

There have been quite a few posts by Trail Rated owners who have been complaining about how loud the Patriot is at highway speeds (110km/h is around 3000rpm for them), so it is the different gear ratio. That's what I've heard so I dunno...

What you are reporting is normal for the Trial Rated Patriot. At 65mph (104.5 km/h) the engine will rev around 3k.

Wont that will kill you in gas?

KFC
You kill me. I always LOL at your posts.

The CVT2L will burn approximately 10% more fuel than the CVT2 at highway speeds. It is designed for 10 mph offroad use.

As someone has mentioned already. getting Bigger diameter tires will bring the rpms down and may increase milage. On the down side the speedometer will be off and the wheelwells on the Pat are small.

So I'm curious- is there anyone from (or knows) Jeep engineering out there that might know answers to these questions- I'm sure there are lots of FDII owners that would LOVE to know:


1. Is there a reason the an FDII transmission HAS to rev high "at highway cruising speeds"? I understand the need to rev higher for off roading (which my Patriot does nicely), but shouldn't it be possible to rewrite the software to lower "highway speed" revs and help out mileage at highway cruising speeds?

2. If not, might it be a possibility to flash a FDII computer with FDI software so that it would lower the revs at highway cruising speeds?

You can't change the gear and final drive ratios since they are mechanical pieces, and don't relate to anything within the computer. Maybe you can change the shift ratio (shift points) by flashing the chip?

The CVT only has some much range of adjustment to create drive ratios. With the Off-Road pkr your get the super high final drive differential gearing. The diff gearing is what you are noticing. The STD trans get 4.12's the basic CVT gets 6.12's and the CVT2L get a crazy tall 8.135 diff pack. The higher the ratio the higher the rpms at any given transmission ratio. The only possible fix to your problem would be to get the shorter diff gearing but you will loose torque in low range.

What are people revving at with the 5 spd? At 110 kph i am around 3000RPM too.

The 2008 5MT 4WD Patriot I test drove did 2150 RPM at 60 mph which means about 2500 RPM at 70 mph.

On the 2008 CVT2 2WD I test drove, the RPM at 60 mph varied with whether I was on the level or going up a slight rise.

The other day I was picking up speed on a very very short on ramp. The Jeep reved all the way with the needle buried. The engine was making a very loud rev noise too. I let off the gas quick. I can't see this being too good for the drive train. I have the CVTII.

I haven't tried this myself, but I've heard that putting the pedal halfway down and letting the CVT shift down and then putting the pedal down further works better. Also, you might have your dealer check and make sure you have the latest engine management programming.

For better or worse, I understand we have electronic throttle by wire, and shift by computer with the CVT models. :)

I think this is a common bug in the 2007 CVT's. Get it flashed at your dealer and you'll see an increase in the milage and better throttle response to boot.

Well that seems alot better than what i get, i payed attention today and im at about 2850 for 68 mph (110 kph). I wonder why im revving so much more. Being a 5-spd it shouldn't slip or anything so having some more resistance from my roof basket and lights shouldn't matter, or am i wrong on this?

I had the dealer check to see if I needed an update at my first oil change, he said no. I think it's because I hammered the pedal because of the super short on-ramp. Going to have to watch that.

Unless your clutch is slipping under load, which we will hope is not happening, your roof basket and lights shouldn't matter.

I was talking about a 2008 US model. If you have a diesel engine or another market drivetrain, it could be different. You might consider making your general location part of your signature so that we can get an idea of any peculiarities in your area.

My 4x4 (non Trail rated Patriot Sport ) with CVT cruises at 60 mph using 2,000 rpm. My 03 Toyota Camry four speed 4 cylinder automatic cruises at 60 mph and also runs at 2000 rpm. Since 4th in the Camry is an overdrive gear, I would have to say that I feel the CVT does have overdrive, you just don't see it listed on the shifter.

The Camry is very efficient and gets 30 mpg on the highway and about 26 around town. My Patriot gets around 22 around town and 27 on the highway, which is not bad either.

What are people revving at with the 5 spd? At 110 kph i am around 3000RPM too.

I have an 07 5 spd and at about 70mph it is around 2800 RPM to 3000 RPM as well. You would think that if the RPMs were that high they would just toss in a 6spd like in the liberty or wrangler.
