Not Ben. I know, I knew this would get interesting in here knowing about what Nick has done in the past with the rod situation. This is very hard to explain without saying too much. Trying to figure out what I can give you guys or not. Iíll know more in a little bit

Default 5 speed to 6 speed conversion.

Will the existing kits or the new kit work with a Mike L built transmission? Just keep Mikes springs in the valve body? Iím very interested in this, since I put 4:30 gears in my lly a couple months ago and it would be great to get the rpms back down when running 75 or 80 on the interstate. I do love the low end now though!

No matter who does it or how it's it's done at the end of the day it's a 6 speed conversion.....its not that amazing in the 06 and up trucks it came in and the big fuel economy and other benefits aren't going to be there with 5-6 conversion either. For some it may be just what they want but it's nothing I've ever or ever will push when you weigh the cost vs actual results for the majority of people.

I'm guessing the tcm won't be open for us to make our own changes?

If the TCM is unlocked, I'll buy in in a second for my GMC, and possibly chuck the Suncoast 6-speed conversion TCM in the Suburban for this as well. The Suburban is a stock (hard parts wise) LB7, so the Suncoast 6 speed kit is great, but I can't run a locked TCM on my built motor. I'm changing things too often that require remapping the shifts to keep street manners.

But I am guessing it is locked, like the rest. I understand why they do it, but I don't have to like it.

And thatís the conclusion I always come to thanks for the honest reply Evan
If someone is really worried about mpg they should sell their truck and get a Prius

Well, the same thing can be said about trying to run 9s and faster in an Allison. At the end of the day, it's still an Allison; a transmission that was never designed for any kind of racing and provides no benefits at all trying to use it in the field either. It's ancient tech. If someone was trying to build a full tilt race vehicle, an Allison is on the bottom list of recommendations as well. It's not for everyone, but there are still people out there trying to use it. No difference here. Because when you weigh the overall cost of trying to use an Allison to run 8s and faster vs better options out there, the cost effectiveness is just not there either.

But we do it anyways.

If everyone was honest and trust worthy it wouldn't have to be locked. But unfortunately this is not the case.

For the avg guy this would be great if the price is right. The 5 speed was my biggest complaint with the LLY. On a back road at 55 I was right around 1700-1800 rpm and all was nice and quite. Get on the interstate running 75 and rpm would be around 2200-2300 and a little loud. It was not the end of the world, just a little annoying.

I would pay in the $300-500 range to have gotten a six speed but that's about it.

I figured you'd have an ornery post and I understand you taking offense because of your time invested and it being your project and I agree on the Allison not being a race transmission because well...it's not. Unfortunately what I said is true and no way of going about is going to increase its effectiveness. But some people will still want just to have it as with many other modifications. I build competition transmissions on the regular and I get not even a handful of 6 speed conversion request a year so that says all I need to know. Unfortunately not to many people want a $20,000+ TH400 swap and 47/48 are far from the best option. This just my opinion from what I've seen and I apologize if you're taking it personal that's not my intention. It's great to have incredibly smart people like yourself in the industry who are able to come up with ideas and actually apply them.

you cant hardly get parts for that price. Imo its more worth the swap if you do a lot of traveling with small or no trailers. Which is what the guy that came up with it does.
