Im looking for a tunning box or some add-on that can change the shift points of the CRD. Anything out there?

Why would your want to? Shifts now dead on with the torque/power curve of the engine. I imagine if you really wanted to you could change the shift points with the existing software on the tranny, but I wouldn't do it unless I had it on a wheel dyno to ensure you got what you wanted or you'd be at it forever guesstimating things.

TDI Dave -

When you find something, let us know. I've looked without success. Even the dieseltuning module doesn't change the shift points (but does increase the hp/torque).

Spoonplugger1 -

*I* would want to b/c the damned thing won't "shift" to high gear unless you're going over 50mph. Much of the driving I do in urban areas never lets me exceed 50... consequently never getting into "high" gear.

Now... are you saying that even when just tooling along @ 48mph, at 2200rpm, that the motor/transmission is "dead on"??? I'm sorry, but I don't agree.

I know what you mean however the change up points are determined on the vehicles ability to drive cleanly the a 2200rpm when my Jeep shifts up I go to around 1450rpm and am right at the bottom end of any real torque which arrives at 1800rpm like a freight train.
Diesels are just like that no pull whatsoever then all at once, trust me you guys should be grateful you didn't get the 4 speed Auto we had up until the 05 model, it was scary to drive as you could never regulate on and off boost driving.
I do agree on the point made however, but at 48mph and 2200rpm and light throttle loading the Turbo is not really working per se' so economy is not in real danger only ears

I respectfully disagree. All engines no matter their type when using a transmission is "spot on" if it is not overspeeding or wasting fuel in a lower gear and when shifted into the next higher gear it is in the power curve of the engine and not floundering which also wastes fuel. By your own admission you are driving around "spot on". 2200 rpm is not overspeeding nor overfueling the engine, and 1400-1500 is well within the power curve of the engine with is a peak power/efficiency at 1800.
Even the truckers have to go through this rpm range we're talking about in their trucks and how many gears do they have?
In the 70's pickups were running around with 3 speed auto/ manual or at the best a 4 speed manual, somehow the job got done.
This rig we own is a phenominal piece of equipment. Tow something with it or take it off road it will surprise the hell out of you. Publications were averaging 18-19 mpg out of it in their hwy/town/offroad tests. What are the other rigs getting?

Doesn't the Dodge Magnum R/T w/hemi use the same tranny as the CRD Liberty automatic? If so, what are the chances someone could adapt the "Tip-Tronic" shift control from the Magnum to work on the Liberty? It'd sure be sweet to have that level of control over the tranny.

Just fuel for thought. I'm not game (or experienced) enough to do such a modification - but surely there are those among us who would know how feasible this might be!?!?

Anyone?

You Crazy.....

Tdi Dave,
I've had almost 30 years experience in diesels. 10 in design, application, and fabrication of custom systems. Have spent 4 years as an instructor. I respectfully agree, I crazy. I'm happy with an engine and tranny that makes as much or more torque per liter than any of the pickups off the factory floor and does it about as seemless and efficient as any system I've seen. I've seen 30 years of a lot worse.

The LX cars (Magnum, 300C & Charger) us a completely different transmission, a MB unit, built under licence in the US. It is nothing like the trans in the Liberty CRD, the CRD has a strange tranny, it really has 2 second gears, and is not a 5 spd tranny in the sense that you are thinking.

Go here and read what it says about 45RFE transmission, it what in the CRD. http://www.allpar.com/mopar/four-speed-automatics.html

Old Navy,

I believe the CRD has a five speed auto known as the 545RFE. This is the same tranny Chrysler uses behind the Hemi in Ram pickups and Grand Cherokees.

Go easy there, bud.

Old Navy,

The 545RFE is actually a 'six' speed five speed auto. It has 2 second gears to choose from, as you mentioned, but it also has dual overdrives. It is different from the 45 series. Again, go easy, dude.

545RFE, AUTOMATIC MULTI-SPEED
Three planetary gear sets, one overrunning clutch, with Electronic Range Select (ERS) driver interactive control, electronically controlled torque converter clutch.
Gear ratios:
1st - 3.00
2nd - 1.67 (upshift), 1.50 (kickdown)
3rd - 1.0
4th - 0.75
5th - 0.67
Rev - 3.0

Yup it has 6 different "gears" but it only uses 5 on the upshift and down shift, so that is why the tech manual list it as having two 2nd gears, not six gears up or down. It only ever uses 5 gears.

Yes, it only uses 5 of the 6 gears when upshifting...but it is a 5 speed (545RFE), and not a 4 speed (45RFE, a tranny that uses 4 of 5 gears when upshifting). The CRD has the 545, not the 45.

Yub that's correct, just get all the numbers mixed up sometimes.

Speaking about this tranny, have you check it to see if you need the TSB done and have you had the dipstick tube sealed?

No, not yet. I was planning on crawling underneath this weekend and checking the tranny number on the pan.

Driverside on the case is a white tag with about 3 letters then the ser.#, all you need is first four. If tag is gone it's also engraved below that with hand engraver and is kind of hard to read.

Have you ever had a CEL (Check Engine Light) that went out but didn't come back on? If so have the scanner put on it to check for codes. Ck TSB listed below. These cars will reset a code like this 3 times and after 3rd time CEL will not come back on.
