DZL_LOU,

While I appreciate the post, I didn't mean to imply that I doubted what you all were seeing in the manual. I tend to doubt anything a dealer says, but most on this forum are pretty straight shooters. I admitted my mistake, only to have Mr. Mopar post something that seemed to support my original position that this info would be across the bus. I have said it before, but I wonder how much contradictory info the dealers get when they try to work on these things.

Joe,

You could be right about the master conflict issue on the bus being the underlying reason.

Not to hijack the thread anymore, but I read through some SW documentation and found out what the wire is for.

The trans torque request is for the TCS (traction control system) that's a part of the vehicle stability package in the edc sw. Because the EATX trans controller is old, this is accomplished by means of this wire as opposed to over CAN in newer applications. The rest of the trans communication (temps, emergency shut down, etc.) is over the CAN bus.

Thank you Mr. Mopar,

That makes sense.

Count me in as well.

The issue as I see it is fraud.

The vehicle is not as I test drove it in March of 2005. It has had the performance systematically reduced by Daimler-Chrysler.

Count me in as well.

I had the F37 done and converter changed. If i keep a light throuttle I still have the shudder. The only thing I like about the recall is the new shifting pattern in 4-5. I do get a better mileage as well. Also, on the same hill near by my house the CRD does not pass 70 mph and before it was able to climb it faster. So the lost of power is very noticeable. I do run the module DiGI-CR on the CRD and the performance are much better. The CRD climb the same hill like if it were flat.

Negating the torque reduction request will actually slow down performance.

What happens when a you shift a manual transmission from 1st to 2nd gear? You let off the accelerator while disengaging the clutch, shift, reapply the clutch and accelerator, and WOW your're in second gear.

What happens when an automatic shifts? Anyone you know let off the accelerator? Does the vehicle instantly change speed to match whatever RPM the engine is running? No. The transmission forces the engine to a lower RPM. The faster this is accomplished (with less engine torque) the quicker you can get on with life in the next gear.

This is off topic.

Where I merge onto the freeway, after 4 miles of driving the CRD would get to 65 m.p.h. before the top of the hill easily. By easily I mean I am trying to maintain 2,500 r.p.m. as the average until it shifts into top gear and settles around 1,900 r.p.m.

After the recalls it will not reach 65 M.P.H. at wide open throttle to same speed sign.

Maybe the county has moved the sign? Or Daimler-Chrysler has reduced the amount of power? Mine goes slower with less torque.

At one point in my life I had a Ford with an automatic transmission and a 390 c.i. engine. I did not release the accelerator in any way while the transmission shifted gears. How did it accomplish the task without damage? The engine produced over 300 horsepower and torque was over 400 f.t.-pounds.

What happened after 60,000 miles? No engine detune, transmission still operating, still fun to drive. Fast forward to 2005; test drive vehicle, like the torque and the way the vehicle drives during the test drive. Buy vehicle. Daimler-Chrysler changes the way the vehicle drives. I no longer the like vehicle because of the changes made by Daimler-Chrysler.

Again off topic, bad writing, responding to what has happened with prior vehicles and this CRD.

Reading what you guys have to say about the F37 reduction in power has got me wondering. I for the life of me can't figure it out. If my 12/05 built 2006 CRD is SUPPOSED to have the same programing from the factory as you all now have, and the same "beefier" torque convertor that you got in the F37 recall, why is it that I think this thing runs like a scalded dog and has probably like 50% more power than I will ever use? I like performance vehicles and used to be at the drags every weekend with my old stang. Someone help me here. I don't see where it is all that bad.

I'm right there with you BVCRD.

I expected the CRD to be a slug like most SUVs, and sure enough, it's no Viper, but for an SUV, especially with a small 2.8 liter 4 cylinder in it, it's a BEAST!

I was pulling out into traffic the other day and some cars were coming so I mashed the gas. There was a bit of turbo lag, then BAM, the rear tires broke loose and the rear end actually stepped out...in a freakin' SUV! (guess I should have put it in PT4WD. )

More power is always nice, and the CRD sure could use some once it gets past about 50mph or so. It's runs out of steam pretty quickly. Maybe the F37 took the torque away from the higher gears or something, because down low, the little 4 banger is a brute.

An engineer said the other night over on Jeepforum.com that the torque was indeed taken away at the higher gears. Something like 10 ft/lbs. Kind of minimal if you ask me. I think running out of steam at higher speeds is pretty common for diesels. More torque down low, then the bottom falls out.

He said the torque reduction was about 10NM, which is about 7.5 ft-lbs. I still do not understand whysuch a small torque reduction was important unless he was correct about it reducing vibration.

The scoop I got was indeed a torque reduction, but did not get how much. Also, the issue is the '05 MY introduced a dampened torque converter in which some rivets breaking is the failure mode.

The cure is to replace the converter with the '04 MY converter which is not dampened and had no issues and reduce torque to '04 levels. Did the '04 vehicles have the 2.8L engine for export? I know there were no Liberties sold in the USA with diesels in '04.

Either way you slice it, we are getting what we purchased taken away from us, both in torque converter design and torque. That's BS.

We have had the F31 recall for some time, and I believe that already had the torque reduction as well as the shift point modifications of F37. So far with 35K miles, we still are find on the original converter, and I'm going to run it until it blows up (7/70 warranty). I will then replace it with aftermarket parts, and chip the h#ll out of it).

The 10NM torque reduction amounts to about 2.5%, and only in the "top gears". I cannot feel the change in acceleration, but notice that the shift points are different.
