Oh shoot sorry I didn’t realize the truck wasn’t near you. I can definitely pull mine in the garage tomorrow and measure the tranny length if you think that’ll help you.- 907powerwagon

swap my 66RFE for a G56....cost?
Hmmm interesting idea. I can definitely measure the 66rfe but I doubt that’ll help much since I’m sure you can do that as well. If I remember correctly, I thought there was only about an inch maybe inch and a half difference with the g56 being slightly longer. I only looked into it because I was...- 907powerwagon

swap my 66RFE for a G56....cost?
Glad to see this is still on-going! Sorry for such a long break but I was doing training there in Texas and it required all my time. Sadly, I had to abandon the swap and just get my auto rebuilt so I could get moving back to Alaska. It works great now but I would still have rather had this done...- 907powerwagon

swap my 66RFE for a G56....cost?
Im going to go with the cummins rebuilt tranny with the hemi bellhousing from Lazar smith. He has a lot of the other little things i would need for the swap and has been a lot of help. I decided on the 'AE' model g56 which will have the slightly lower RPM on the highway. The gear ratios on the...- 907powerwagon

swap my 66RFE for a G56....cost?
Nothing yet. Just trying to source some parts and figure out which path I want to take (stock hemi G56 from a 3rd gen vs rebuilt g56 cummins from Lazar smith) Going to pull the ECU from the truck soon and send it in to get unlocked. When I get it back ill use the HP tuning to double check the...- 907powerwagon

swap my 66RFE for a G56....cost?
So HP is just the software portion of it correct? Is there a preferred hardware to use? I assume you need a computer program and then a flashing tool to plug into the truck to load it so I was curious on whats good out there right now. Thanks! Edit: After reading for an entire 5 minutes I see...- 907powerwagon

swap my 66RFE for a G56....cost?
Additionally, for consideration of just using the hemi g56 from the 03-08 trucks, I came across this clutch setup after some reading of other forums. It’s better than the stock clutch and claims 641 ft lbs for torque. I’ll never exceed that from what I can reckon. Adds a point to the score for...- 907powerwagon

swap my 66RFE for a G56....cost?
Any of you guys know of any places to find a potential g56 core? I’ve been looking through junkyards, car-part, Facebook, etc., just haven’t had a lot of luck. I can find the remanned g56 for both hemi and Cummins applications but since lazar is going to pull it apart anyways for the input shaft...- 907powerwagon

swap my 66RFE for a G56....cost?
Still putting together ideas right now but I imagine I will start the process after the holidays. I have my daily to drive so it’s not a big rush for me. I’m still debating getting the diesel version g56 with having to change the bell housing and custom clutch setup vs just getting the g56 that...- 907powerwagon

swap my 66RFE for a G56....cost?
update again after talking to jerry and rick at tapped. Rick informed us that you actually only need to perform the unlock on the pcm (since mines a 2015) and then all you need is a tuner from say HP or diablo and you can literally go in there and disable the automatic transmission setting and...- 907powerwagon

swap my 66RFE for a G56....cost?
I did talk to Jerry at Tapped performance about the tuning aspect of this. The 6.4 manual combo was offered on trucks in canada and mexico so the factory operating system already exists. It should be as simple and taking the pcm, unlocking it, and then uploading the new factory tune. Im not...- 907powerwagon

swap my 66RFE for a G56....cost?
Just for clarification, you could absolutely just take the manual transmission that came in the 5.7 hemi and use it behind the 6.4 with the normal flywheel and clutch combo. Additionally you could take the cummins g56 and swap the hemi input shaft and bell housing on to it and then also use the...- 907powerwagon

swap my 66RFE for a G56....cost?
If you use the g56 that came with the hemi's then yes, I believe everything would be normal, however, lazar uses the g56's that come out of the cummins and then throws in the input shaft and bell housing from the hemi so i think that changes the size of the flywheel and clutch because of the...- 907powerwagon

swap my 66RFE for a G56....cost?
The only other thing that mike at lazar was telling me was that with the different input shaft and bellhousing of the 5.7 g56, is that the clutch/pressure plate combo is basically a custom job, which means money, not to mention the availablility of parts. Im not planning on breaking anything...- 907powerwagon

swap my 66RFE for a G56....cost?
Yeah i found the bellhousing upper portion on ebay. All i gotta to is give that and a g56 tranny to lazar in texas and he'll change the input shaft and housing and then its good to go. shouldnt be too cosmic. i need to put together a list of the other components though. should be able to use the...- 907powerwagon

swap my 66RFE for a G56....cost?
I’ve been reading around trying to find more info on this. Talked the the guy at lazar in Texas today about the mechanical portion of it all. That part seems pretty straight forward. Take a diesel g56 and swap input shaft and front upper bellhousing and it’ll bolt on. I’m not sure what would...- 907powerwagon
