Topic: TV - RPMs Posted: 08 Dec 2014 at 9:00pm |
We're towing with a 2014 Cherokee with a 6 cyl and the 9 speed auto. Plenty of time around 3k revs, depending on the terrain. Got 13.3 towing. Just the way it is.

It's very normal to not be able to be in the transmissions highest gear. And also normal to run at higher rpms when doing so. Think about it, your vehicle has just been asked to pull a combined weight of the vehicle AND the R-Pod. Definitely get an auxiliary transmission cooler, it will keep your transmission fluid cooler (burned-up, overheated fluid is what kills transmissions). Don't bother with highest gear, leave your auto transmission in the next to highest gear, unless climbing hills, then I recommend slowing down to keep the engine from getting near redline.
If you can give up the minivan (Honda Odyssey) and go to an SUV, see if you can afford a used Touareg TDI V6... You will get the best of two worlds, a very strong tow vehicle, and very good mileage when not towing. Also add that it handles like a sedan, not a truck. I'm biased on this because I have one and won't go back to a gas powered vehicle. Someday i plan on getting a bigger trailer (small toy hauler) in the 5000-6000 pound range and I will still be well within the tow rating (7700 pounds).
If Jeep works through their issues with the new diesel (mostly electrical problems from what I read), then a used Grand Cherokee diesel would work good as well. It was on my very short list of SUV's when I was deciding what to buy.

On Chevys the tow-haul does change the shift points, it holds it in a given gear longer before upshifting, downshifts more easily, and increases the line pressure to reduce wear on the clutch packs. It also modifies the "single tap on the turn signal" from 3 flashes to 6, and supposedly upps the alternator's voltage but I've never seen that on the dash gauge. Finally it activates a more aggresive engine braking mode.

You're correct: T/H locks it out of fifth, stopping up-shifts at 4th. As far as T/H changing shift points, the consensus on a Durango forum I used to frequent when I first bought the Durango was that T/H did nothing with the shift points. My ten years of towing with the Durango would seem to bear that out, but it's a bit difficult to prove one way or the other. My Durango did not have a tow package, but as has already been mentioned, all 2nd Gen Durangos have auxiliary trans coolers. I added the receiver hitch and wired for brake/lights, so no real difference between factory tow package and mine at this point (other than larger mirrors on factory tow package).

I just got it (the durango) a few days ago. Not sure on the rear differential. Is that on the door jamb tag? |
Wildfire: The tag is located on the glove compartment door (at least on mine). I've owned my Durango for ten years now. It's got over 150k on it, virtually all trouble-free miles. The transmission on these 2nd Gen Durangos is Mercedes Benz-derived (since Daimler owned Chrysler at that time). It's actually a very good transmission, but the lack of ability to lock into 4th is aggravating to me. The 4.7 isn't bad, but it could use a few more horses and foot-pounds when pulling the Pod in cross winds and up steep grades.

All transmissions fail eventually :). If I had a vehicle that towed the camper very well, but I had to replace the transmission every 100k, I would still do it if the vehicle suited my needs more than any other. The Ody didn't tow it what I would consider "very well".
I totally agree with Podster - a lot of money will flow towards the camper for a while, but when you get it set up the way you want, it stops.
True also about the tow vehicle. The Odyssey can tow the camper, but I never felt very comfortable driving it. Just seemed like the Odyssey wouldn't be a confident vehicle if something scary happened. I don't know if things will be better with my Durango, but it weighs a 1000 pounds more than the Ody, so that will feel a bit more stable.
I have driven several truck and trailer setups at work, and towing with the F450 dump truck is my favorite. But not very practical for a family :). Seems the heavier tow vehicles will feel better towing. Someone else posted above said that power isn't everything, balance is more important. For example, a Mustang has a lot of power, but would make a horrible tow vehicle. Towing a 3000 pound camper with a 5500 pound vehicle will lend more control than a 4300 pound vehicle.

Very true statement...I have been shelling out the greenbacks nonstop since the initial purchase. I guess it's like any other hobby, it's take some time and money to get set up, but once you have everything just the way you want it, hopefully, the debit account will resume normal operations.
As far as your TV, if I understand this correctly, you are at or very close to the maximum limits of the rig so getting something with a little more headroom, increasing your load, power, and safety margins is not a bad thing. Additionally, more TV capability garners less stress all the way around which makes making things more enjoyable all the way around.

Thanks for all of the input. Good news/bad news. Good - my Odyssey can handle it and more RPMs is fine. Bad - I have 137,000 miles on it and keep hearing that Honda transmissions may fail. Good - I may get a new TV out of the deal. Its only money. Its amazing how these hobbies seem to have a cascading effect.
