CA conversations stand alone computer for Allison 1000 on 12 valve Cummins Chevy

This is a walk around on a stand alone computer setup for Allison 1000 with a 12 valve Cummins. I took the Duramax out and put in a 12 valve and wanted to keep the Allison 1000. This is what I ended up doing with my truck. The stand alone computer, wiring harness, tps sensor and torque converter were from www.caconversi... I would say they have one of the best customer service. KC and Dave are pretty great at answering questions. You can call them any day of the week and they will try their best to help. Their product is on the expensive side but you get what you pay for.

Sweet setup.

[@travis8404]

very NICE

[@nicholasbryston9518]

Can you share pics of what the engine bay looks like with the cab down. Would like to see how close everything gets.

[@naudydave]

Can you email me. [e-mail]

[@robertdixon8973]

Did you move it 4 inches back to clear the old Pan from the front end?

[@naudydave]

I moved it back to clear for a stock fan setup. I didn’t want to put electric fans.

[@billywilliams6853]

What is the price of the transmission conversion???

[@naudydave]

I had the transmission so that all depends on what you get. But with the computer, wire harness and torque converter, it was close to $5k. I do wish I rebuilt the trans right away. But to do it again I’d probably put a nv4500 or 5600 in it.

@@naudydave Thanks

[@kclogging6995]

​@naudydave why wouldn't you do the allison again with the 12v?

[@HopefulCanoe-yh8oo]

Hi can you help me please, Im trying to use a 2008 allison transmission into my 1995 cummins 5.9 lts but I can’t find the adapter plate to put them together, do you now part numbers or selling one???

[@naudydave]

@@HopefulCanoe-yh8oo so I got mine off of eBay. I know CA conversions sells them. They have everything you would need. They also can reprogram your computer. You also need a tps sensor for that transmission

Do you remember what the price on the full kit was? Thanks in advance

[@naudydave]

So I ordered it in July 2020 so prices could be different now but it was $5100. That was the wire harness and computer reflash, torque converter, tps, starter, torque converter core and shipping. I got the trans to 12 valve adapter on eBay for like $1200.

[@naudydave]

Just email me if you have any questions [e-mail]

[@nobrakesnation]

@@naudydave Awesome, I appreciate all the information! Do you know if this would work for a 01 gas 2500hd Silverado? I am swapping the 6.0 with a 12v and Alison 1000 6 speed.

[@naudydave]

Yea but they do have a different wiring harness and stuff for 6 speed. Also with a 6 speed you can get a display for the gear it’s in. The owner Dave and kc are easy to take to. They don’t always answer the phone but they call back everyone. They are the experts in the swap. They have adapter plates and everything so you can get it all from them if you want.

[@nobrakesnation]

@@naudydaveAh ok that’s good to know. I definitely will contact them. I already have an adapter plate and everything else to do the swap just need harness and computer, so I’m sure they can help me out. Thanks for the information! Have a blessed one.

[@rubenvor]

Thanks for sharing! What chassis is that? How's that independent front suspension handling the weight of the 6BT? I'm asking because I'm looking for a modern rolling chassis for my project, and independent front susp would be amazing!

[@naudydave]

So it’s a 2003 k3500 dually. I didn’t like the Duramax 6.6 so I put the 12 valve in it. It handles perfectly. I did raise the front but that because I use it to push snow with a older 9 ft western plow and that thing is heavy AF. Also it the brackets hang low so I wanted some ground clearance

[@rubenvor]

@@naudydave awesome man! Thanks for the input 👍🏼 May I ask something else, what about that Allison? Do you like it? Would you have gone a different direction?

[@naudydave]

So I should of rebuilt the Allison when I had the cab off. I think if I did it over I would of got a nv4500 or another manual trans to make it less expensive. I’ll probably end up pulling the Allison out and rebuild it this coming spring.

[@supersport1986]

@@naudydavesweet build! Not very many of these are out there that are actually on the road! I have a 2005 2500hd that I 12valve nv4500 swapped 2 years ago and it's been great have put about 20k on it since the build I used the cooler stack out of the dodge so i was able to run the mechanical fan and i was even able to use the stock drive shafts only frame mod i did was move the carrier bearing up 2 inches for getting my driveshaft alinement right only issue so far is my t case wont shift in to low anymore and I'm not surprised honestly it wasn't in good shape when I put it together I used the 263xhd worked great up till about 2 months ago but I have no regrets on the build otherwise if you look up cummins swapped 2005 chevy 2500hd you will find a vid on my truck my channel is supersport1986

[@darrinstone49]

What are you going to use for hvac vac?

[@naudydave]

I have the stock gm pump on.

[@bodereiss]

What fuel filter and housing are you using? I've looked for a CAT filter conversion for the 12v without much luck. Thx

[@naudydave]

So I used one like the link I put. But i did have to machine it to fit on the 12 valve www.ebay.com/itm/265751345017?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=52f-JFYiQgm&sssrc=2349624&ssuid=ViaQduRPRay&var=&widget_ver=artemis&media=COPY

[@bodereiss]

@@naudydave Perfect-thx. I'm surprised someone doesn't make one that will fit the factory banjo fittings.

[@naudydave]

I ended up doing braided lines and the adapter was metric o ring threads. It was a lot of messing around till you get them right. I also got banjo fittings to an fitting and the fuel intake of the p pump and the return

[@bodereiss]

@@naudydave OK thx- I’ll probably try to cut and flare the factory tubing to save the ends and put the braided line in between.

[@derekpiazza6967]

The filter just screws right on man you don’t need anything but the filter it’s same threads and everything lol

[@Ashroyer86]

Does it shift harsh?

[@naudydave]

No but I do need to rebuild my trans. I should of done it when I had it out right before this video
