No, this is not true. The 545RFE transmission used on the Grand Cherokee and Commander can handle 100% of engine torque from the 5.7 Hemi in all gears.

Oh, and the other suggestion- maybe a little offopic since it's not strictly technical, but I believe you should note it and do something with it:

I bought my GC in USA and shipped it to Europe. I have written to customer support and received a lot of great information, until I said that I shipped it to Poland (I did it to be polite and explain, why I gave false address to send the message form). Then I only received "we do not support private import", and that was it. Whatever I was asking about got the same response. This is not how the jeeper should be treated. Remember, that people who buy used Jeeps help them keep resale value. Good resale value = another reason to buy new jeep. Take care of your product users, no matter if they bought new or used one... You can only get benefits this way.

Well, no ones asked it yet....lol

Any chance of the next model having a solid axle in the front? It should.

Also if I were buying a new vehicle in this class, I would be looking for mechanical options not luxury "fluff" such as lockers, gearing, and skid plates. Also I would definitely give preference to whichever model offered a manual transmission, as would a diesel option (where I didnt have to pay 40k for unneeded options, and that wasnt a Mercedes engine with no parts available).

Thanks for hearing my opinions.

Thanks again for the suggestions!
I dont see the answer to number 9. About 5 of us have brought up the topic of confused transmission in 4 th gear. If possible, could you address this question directly?

Thanks,
Rob

Also what HDC said was true the Hemi engine really burns gas. It is nowhere near the 14 city that is on the window sticker. I get 7-8 mpg in NYC. But what the hell I didnt buy it for economy, only for power.

Any possibility for a 3rd row of seats in the Grand Cherokee? This would sway us back to Jeep for "Mom's Car".
We do not offer the 3rd row in the Grand Cherokee but the Commander has 3 rows (seating for 7).

Some of us would also like to offer a more aggressive A/T tire as an option so keep asking - we do have other constraints such as road noise and fuel economy objectives to meet also.
No problem on the input. Like how the Rubicon is for the Wrangler and the Power Wagon is to the Dodge Ram, I think a Jeep Grand Cherokee that has the same or similar capabilities would be ideal.

I would also like to thank ya'll Jeep engineers for putting the CRD into the WK. People have been wanting a diesel in something other then a HD truck and now we have it.

Will there be an issue with parts/service support for Diesel WKs since DaimlerChrysler split? As I understand it's Daimler's 3L engine

Thank you.
We like to hear what our customers are looking for, can you help us with why you would like this feature?

We do offer part time systems in Liberty and Wrangler, however the larger Grand Cherokee and Commander drivelines would require a significantly bigger rear axle to handle all the torque without sharing the load to the front axle (the 5.7L Hemi and 3.0L diesel 4x2 models both use a different axle than the 4x4 models. It is not available with the ELSD.)

My dealer doesn’t know anything about this yet. I actually have an ’07 and would like to add the factory parkview camera system and view it on the nav screen, but am waiting for this update. Do you have any additional information on this? Is it already a dealer option on the starscan if it’s an ’07? Thanks.
Depending on your type of radio (needs to be a AN level or later, check your p/n), you can install a rear view camera and the previous response was correct, you will need assistance from a dealer. Remember, in order to install this feature on your own, you can void your warranty. I would recommend the Mopar rear view camera system. If you do decide to proceed on your own (Caution, Caution.), you'll need the radio, rear brow with camera, wire, i/p bezel... etc. Once it's all installed, your dealer will need to configure the FCM (front control module) for rear camera using a Starscan.

We looked at the Commander and we did not care for the looks or the storage capacity - the Volvo actually has more cubic footage.
We still love the Grands.

I can understand why Jeep would not want to canibalize sales (take Commander sales away with options on the Grand) - but it sure would be nice to have the added flexibility.

Thank you for listening!

Bottom line is reliability and simplicity. Sometimes you want things to be easier to work on and replace. As the owner of a 93 with the nv249 case, I would much rather have a part time case like the 231. As far as a bigger axle goes...bigger axles are stonger axles. No one here will hate you for giving us that. We like stronger things.

Thanks for the answer.....I was told that the torque management program limited the throttle in first gear.
