Now anyone who is a mechanic for chrysler may want to chime in if there is anyone. I am doing reading on the crds and i found there is a 545fre transmission(same as my truck) and i was wondering if it would have the same bolt pattern as my truck. I have 3 converter in my possession as of right now. All billet and all can handle 550 ft lbs or 500 hp. With that said i was wondering would they work?

Im getting some specs on the 545fre from my truck right now as far as the bolt pattern

It's 545RFE. 2005+ KJ's have them.

Pick the one with the stall ratio closest to the CRD and make sure you use Red Loctite on the four bolts.
SunCoast worked it out on what Stall Ratio is best for the CRD with an enhanced tune, but they don't let that info out, they paid dearly and spent a lot of time to get it right.
The CRD engine reaches its' peak torque at a lower RPM than the Hemi, that is the best I can tell you to pick the best one.
Your TCM will learn the right line pressures with some driving to adapt to the trans/torque converter you put in.
Recommend you add the Transgo kit including the valve for the front pump.
PM me if you want to play around with the TCM too.

well im going to contact a company i have done my converters with before info with and i found out these are the same converters as in the dodge trucks or anything else using the 545fre meaning he can build a custom billet 9 inch converter from 3200 to 4000 to a 11 inch converter anystall from 2400-3200 based on dyno number and torque give him a dyno sheet

this guy knows his stuff and has actually done a few jeeps

ill let you guys know more when i get everything in

this jeep is turning out to be a nice lil investment

I would just suggest getting the Suncoast converter for the CRD, Ron and the crew at Suncoast have tested a get deal with both the CRD and Hemi version 545RFE's. The Hemi version has kinda been a "pet project" for Ron and his son with both truck and car gas applications, which has resulted is some very interesting one off creations. The CRD 545RFE is very similar to the Hemi version 545RFE as far as the tranny, but the converter reacts very differently torque. I have a very close relationship with Suncoast allow me take the Suncoast converters apart and try different conbinations. I've tried the different Hemi multipliers and you will end up back to the multiplier design for the diesel torque. The higher stall converters just don't work in these CRD's, or any diesel that makes any kind of power(relative to it's starting HP). I wouldn't try to re invent the wheel, just put a Suncoast tc in it and be done.

X2 I spent 5 weeks in Ft Walton Beach, FL on a work project, Ron is a Great Guy and has the talent and knows the Art to select the right components to make it work. When I was there one time he showed me a Euro that they bough new and dissected to find out what the changes were, bigger dampener springs, nothing more. After doing more research with a couple other CRD guys, we found out the bigger springs is what VM told Chrysler to use from day one.
Engine vibration is also reduced since the front billet cover gives more flywheel which the CRD lacks with out the SunCoast.
When I upgraded to my InMotion II tune, it worked even better.
The TCM I transplanted out of another Mopar shifts at lower RPM and the SunCoast can take the full torque of full boost at 1200 RPM with out complaining. I don't want to spill too much on my TCM, but the 545RFE TCM is a smart TCM and will adjust your pressures to your driving. Any change you make like adding a Transgo Kit, SunCoast converter, or stronger tune will send the TCM onto a new learning experience.

Not to hijack this thread but I have a question to the discussion taking place. If the TCM learns, what Transgo kit is best to use? Obviously the resistor would be a waste if the TCM will just readjust the line pressure accordingly. Is there a difference between the two kits other then the resistor? About the Suncoast converter, if you get a GDE TCM tune do you really need to update the converter from the euro? I really like the Suncoast but that baby has one hell of a price tag. Also, if you do get the TCM tune do you really need the transgo kit? I have no experience with the 5-45FRE transmission so this is all a bit of learning for me.

Phatjimmy.

Since you already have the EURO TC there's no need to replace it for either the GDE full torque or hot tune.
The Euro TC is standard eguiptment in the newer VM Panther engines.

I say go for this torque convertor redesign if he can create on cheaper then the Suncoast but perform just as well why not? Plus i would really like to see the Dino numbers on a stock CRD and see what the torque curve looks like. I Just have the Euro convertor and i can feel a very distinct vibration when i push her hard coming on to a high way. So please go ahead and experiment and share please

Does anyone know what converter comes with a brand new trans from Mopar? I never got an answer back from Moparpartsamerica. I

audiboy86 · **Posted:** Wed Feb 02, 2011 1:56 pm

I would suspect the latest version of the euro style convertor unless they still have some back stock of the older version. But as common as this transmission is i would suspect not.

Any thoughts on the transgo shift kit? Is it worth it and what kit is best for our little CRD's?

audiboy86 · **Posted:** Fri Feb 04, 2011 2:43 pm

The Transgo reprogramer kit is the one you want and it is more then worth it they may a big difference in how your transmission reacts and shifts.
