I bought a 2004 excursion with the 6.0 connecting rods laying in the pan. I want to put a 12 valve in the excursion. I love the simplicity of the 12 valve. Reading info from desrokedand fordcummins.com one recommends a new toruque converter, the other does not. What is the best thing to do? I beleive it has the 5 speed auto but I have not looked into that yet. I have been busy building my garage for all the projects

I am also interested in the same project and I am looking for a doner Ford as I print. Have you had any progress yet?

IHC, Probably the best would be to throw a G56 in there.....

That being said, I would probably get a lower stall converter myself. I assume that is what they are talking about, correct?

BTW, not sure if you ever saw this thread, lost of good info there for your swap.

Yes, go with a new converter to match the Cummins torque curve.

The 7.3 had a 4 speed auto, 6.0 had a 5 speed, and I think the 6.4 did as well, the 6.7 powerjoke has the 6 speed auto.

i have brand new TC for the destroked adapter and the 5r110 transmission for a 12v. I went with a manual instead

I agree I like the manuals as well. I do have a NV 5600 with the big input, but most likely it will go into a pickup. Best pickup I have driven was a 97 12valve with a small input nv5600 swapped in place of the 3rd or 4th broken NV4500. The excursion will probably never tow more than a a skid loader on a 14000 gvw trailer. No progress building the garage ate all my funds. But I do have the garage up. Still needs to be wired though. The concrete bill tore me up.

I have read 5.9excursions thread about 4 times and I am extremely impressed. I am not sure I could have his patience to wor through all of the electronic issues. Right now I am working out of state and doing more research as I save for the conversion. I am totaly undecided about the transmission choice as of right now. Motor wise I will have the head O-ringed and put in head studs. KDP tab of course. I am thinking of using a cam from Colt (they claim a 1-2 mpg improvement). I will also put in new injectors so maybe some 40 to 60 hp injectors. Not sure what turbo I will go with. I will probably keep things simple and keep the mechanical lift pump. They have been reliable in my dodges. I am not looking to get wild, as I want a reliablle truck to tow with low egts.
back to tranny choices. My truck is a 6.0 so I could keep the 5r110. Disadvantages are high cost of adapter, tourqe converter, flexplate, psc controler, and all the tuning needed. THe price for these parts are about 3500. that does do not include the rebuild on the tranny (at least 4k) What company builds a great 5r110.
I also have an auto from a 96 dodge. No adapters needed big money rebuild needed to make it reliable. Tcase would have to be adapted or a floor mount shifter installed. Not sure if these need to be programmed or if they can be built strong enough to be reliable.
Manual options pluses are no transmission tuning and possibly lower cost. Disadvatages cutting shifter holes. possibly difficult the adapt clutch pedals and hydraulic clutch pieces.
ZF 6 speed I would have to go find one and the pedal assemblies. My friend has one in a 99 ford. Plus is using factory ford parts. Is has always been a notchy shifter.
NV5600 I have one with the large input shaft. I have always liked this tranny in Dodges Disadvantage is that this transmission has very little support for replacement parts. Probably would have to use a dodge t case.
NV4500 I would source a fresh rebuild with the upgraded shaft for 5th gear. no adapters needed to engine. Probably have to use dodge t case.
G56 I am told these are pretty good. I would have to find one though. We have a 2010 dodge w/ a G56 at work. It seems to take out very fast in 2nd gear. I will assume that Dodge has 3.73's. it has stock tires. They just put in a south bend clutch ( not sure what model clutch though). This truck has had a bad history of eating clutches ( bad drivers probably). This annoys me as all my 2nd gen Dodge take out smoothly in 2nd. So I am open to all discussions What have all of you done to adapt manual trannies. Should I worry about programming an auo? Being a truck driver I like a manual, but an auto is a nice change of pace too. Please give me your input.

I personally would look for a 94/95 47RH, gets rid of the PCM control of the 96 up RE. You could use your existing NV271/273 TC by changing the input adapter to the Dodge 23 spline.

Trans isn't really terrible to build if you just do a good triple disc TC/Valve Body and band strut, talk to Goerend for specifics for your application.

If you need a set of pedals for the manual swap though, let me know, I have a brand new in the box Ford setup for 99-04, I probably will never do anything with it.

P.S. the same thing works for a NV4500/5600/G56 in regards to your TC, all you would need is a 29 Spline input for your 271/273, about 200 bucks new the last time I checked.

Thanks Patdaily. That is certainly the type of infomation and advice I was looking for. I do have a complete 94 dodge that has been totaled. I was thinking of swapping another 94 cab and bed onto the chasis from a gas truck I bought for the body parts. Maybe I will just use the drivetrain from this truck. I thought I read somewhere that the floorpan is lower in the excursion than the ford truck, making it difficult to swap in a manual. Do you know if that is true? If it is I may just do that 47/rh. It starts to sound like the simplest and least expensive option. My 97 needs a trans rebuild as well maybe a transmission builder would cut me a deal.

patdaly

No, sorry, I am not familiar with the Excursion. I do have to wonder though how it could be much lower, as they had powerstrokes and the 5R110 trans with the big TC...........

I'm doing a a 04 f350 with an auto this time with a cr and it has the 5r110. From discussion with fordcummins guys you dont need a trans controller most of the time now with a vp motor and rarely at all with a cr. Also you dont need a new torque converter, you can still use the ford one, just the flex plate and adapter.

ihc4bt

I did see on the Fordcummins site, that a converter was not necessary. I did not realize that a controler, may not be necessary. I will send them an email and see what they recommend, because mine will be a 12 valve. Thank you your input.

I don't see how you can get away with not using a trans controller on a 5R100 (or 4R100). Basically, ANY of the electronically controlled auto's HAVE to have a PCM to control shift points, it's just that simple.

Now, maybe you are talking about dropping a Cummins into a Ford vehicle, and using stock computer for the Ford trans????

However, you are still using a computer to control that trans. My question would be, how would the PCM control trans, if it wasn't getting any feedback from the engine?


That, Im not certain on, but I am 100% certain that any electronically controlled trans, HAS to have a computer to control it. Period.

after reading the post rich made I started studying Diesel Conversion Specialists website a little more. Here is some good info on using a 5r110 http://dieselconversion.com/knowledg...R110-Torqshift

I am interested in this although it may still require a programer. I may still consider installing a manual trans, for cost reasons. I already have one, plus my Excursion had some high miles on it when the motor let go. I would hate to get it up and running then, have a transmission failure. A rebuild would be expensive I would think

heykw

Has anyone used the dodge Trans on this swap?
