The video is nice to watch and full of info with some tips and tricks to make it easier. If you wanted to down the road if you ever get tired of that starter placement, you could order the ATS Allison bellhousing to mate up the 68fre adapter plate. Then you can use the upgraded 47/48re flex plate and have the factory starter location. But I'm not sure if you have to have a custom torque converter made though. ATS had their own bellhousing casting done for the Allison so it could mate up to the 68rfe/Aisin engine adapter plate.
Honestly, once you do the starter swap along with the wiring change involved, it would be kind of a pain to switch it back, especially since the CAConv adapter plates etc. are high quality and work well, and once it's done it's solid! I'll admit I was skeptical about the replacement starter, which is physically smaller than the original, but then pleasantly surprised when I found it cranks the engine over faster than ever before!
Great video. I have a 12 valve with nowhere near the power youre making. I have been considering this swap, curious if youre still happy with it, any problems. Just looking for an honest non paid for opinion. I love my old truck and just want it to tow a little better
I actually have not used it all that much yet since so busy with other aspects of life, but it's been really great so far overall. However, I am currently having some erratic shift behavior which has been linked to my Throttle Position Sensor (TPS) not producing the correct percent throttle to the transmission which I have verified with my scanner, so I have a new TPS coming soon. When I explained the behavior to KC and Dave at CAConv, the immediate response they had was to check the TPS. Sure enough, it would bounce all over, and often read 53% when my foot was off the pedal to let it downshift naturally. It has downshifted HARD at about 1100 rpm when it sees this value, and only then, so that's not a tranny problem, but my TPS which I have never replaced in 24 years. But more to the point, it is AWESOME to have a 6 speed from the 4 speed. The shifts are firm which I like, and I also love the 2nd OD at 0.61. Great for cruising 75 or 80. The 47RE OD is 0.69, but 4 speeds leaves a lot to be desired. And reverse on the Allison is about 4.4, which half the speed of the 47RE, and I've always noticed reverse is geared way too high. So the gearing on this new tranny is very pleasant to me, and the confidence of its ability to handle the Cummins is truly a great load off my mind! The tap shift feature is also great, you can limit what gear it will get to, and also downshift more aggressively if you want. So yeah, if you love your truck like I love mine, it will endear you to it all the more, and it will definitely tow better and more efficiently.
You want to sell the transmission pan off the old one I’m having issues with my 48re was thinking about doing a swap like this but maybe in the future I just use my truck for heavy towing
Can you elaborate on that? Not sure what you mean. The shifting feels a lot different from my 47RE, and the TC lockup between 2 and 3 is really nice, especially since it stays locked from then on and all the way down!
Check out the @brentjones response I gave below. I'm totally loving it. But I need to replace my TPS (in a couple days) to fix some goofiness it is causing
@@RobGADV yes, that is a good estimate, mine was a bit more since I got a billet input and some other clutch enhancements. Not cheap, but when you compare it to having a shop fix your failing stock tranny, it softens the "financial blow" a bit since this thing is a MASSIVE improvement!
Actually you're the first, and I agree, but are you thinking the seal is leaking now? The oil pan is seeping, and I'm assuming the oil there is from that, it doesn't look like the rear main, but I may be wrong...

Surprised this video don't have a ton more views
Appreciate that thought, I don't work super hard to make my channel popular like others do! Hopefully folks that are doing this will find it.
Still sounds like the old slushbox shifting.

Can you update us on the transmission?

That shift knob you used was from a dodge 07-09 3rd gen with 6.7l cummins. Not a chevy
Did the 07-09 trucks include a Tow-Haul button function which this has? They indicate it's from a Chevy (2008 Siverado) but I'm not sure myself
@@AlaskaNostalgia66 yes they had a tow hual button the dodge shift knob is round the chevy shifter knob is flat
Why the Allison 1000 versus a 2000 or 2500? Just because it comes with the GM bell housing and tailshaft housing?
Because it has a park pawl and is basically identical to a 2000 series
@@dieselsmoker Yes, CAConversions affirms these other series provide no meaningful benefit over the 1000 series
How much you pay for the transmission?
I'm waiting on a price quote from CAC but I'm expecting it to be in the $12-15k range.

🙄🙄🙄It's leaking.......By now hopefully somebody told you you should have replaced the rear main seal
Actually you're the first, and I agree, but are you thinking the seal is leaking now? The oil pan is seeping, and I'm assuming the oil there is from that, it doesn't look like the rear main, but I may be wrong...
A little oil loss helps keep the floor pan from rusting out🎉
