Hi.

The outside air temp sensor/display seems to have a “funny” algorithm for updates. It works OK for on-road use, but is not good for off-road use. For example, when I start on a trail in the morning, and drive on the trail all day, the temperature never changes until I got back on the main road and go fast enough to make the algorithm happy. Does the engine use this temperature for anything that could cause a problem when the temp reading is in the 50s (early morning) and now the temp is really in the 90s (afternoon)? Is there anything I can do about it?

We are here and ready !

hello fella's and thansnks for an excellent product love my 4 dr jk rubicon in rescue green . my question is as follows why cant we use the lockers at higher speeds and in 4 hi ? i understand the driving dynamics i wish it would have been a little higher.

I have to start with a question regarding the soft top. It seems like they are designed to pour water into the cab when the door is opened when it rains because the water runoff is too short (sorry for the lack of more technical terms). Is there any plan to fix for future models or a retro-fix for current ones?

[carnut08]

Can you give us any information on whether or when the plastic retainer for the transfer case shifter will be improved? There are many reports of failures at both ends of the cable. Thanks

This is normal - the Jeep must be going more than 25 mph. The sensor is in teh grill and needs airflow.

Others have complained when rthe temp reading is very high at low speeds.

Engine controller is fine btw....

Hi JeepEngineers,

(Thanks for coming here to talk directly to us customers - very cool.)

Can you confirm that the new soft top with the cable system will fit on an '09 (two door)? Am I correct to assume that only the door surrounds would need to be changed, is that correct?

Thanks.

OK, that's good, thanks!

Would you like a solid axle?

[joe002]

I was trying to think of ways to keep my automatic transmission cool when off-roading out here in the summer in AZ. I was wondering what would keep an automatic transmission cooler when driving slowly off-road. Setting the transmission to a specific gear, say 1st or 2nd or leaving it in drive and letting the transmission pick a gear. Also, if you put the transmission in 1st or 2nd does it lock up the torque converter?

[MrOrange]

I was also curious, why are there two different bus speed type radios used in Jeeps. I know the Grand Cherokee has the REQ radio but it won't swap into a Wrangler due to different bus speeds.

[442Wrangler]

is there going to be a "chrysler factory lift" extra available in the future on new JKs?

[XJMuscle98]

Are there any plans for a "shiftmatic" or "auto-stick" incorporated into any Wranglers?

I imagine it would solely be a TCU function and allow you to keep the current Jeep transmissions.

I've got an 08 JK unlimited with soft top and have a problem with the header staying sealed at highway speeds on two lane highways. When I meet a semi, the header pulls away from the center and creates an awful wind noise that can't be fixed without stopping, unlatching the header, pulling it up and then re-seating it, very unpractical to do on a 300 mile trip in windy West Texas. My dealer hasn't been able to help since it's in the city and the circumstances are hard to replicate. I put a couple layers of duct tape under the latches to tighten the top up and it helped some, but I'd like a real solution to the problem.

Thanks
