LB7: LB7 transmission help

[walker.b]

So I have a LB7 stockish I'm wanting more power I want to get efi from Rob or duramaxtuner so I'm thinking about building my tranny with the alligator stage V my question is can me and my dad build it ourselfs? He was a mechanic for 30+ years I've heard that home built Allison's won't last past 15k miles thanks fellas

Well technically it will last. You can build a transmission strong enough to hold the power a non built motor will make. If you have bigger plans then get it built.

A proper stage 3 will hold the same or more than your stage 5.

And depending how hard you run a built ally won't last forever either

If you or your dad have never done an automatic trans. Before I'd suggest going to someone who has the experience close to you. Also I'd choose a different kit. There's a lot better "kits" out there.

If you want to do it yourself, I'd buy a kit from Suncoast. Talk to Andrew. Just do your research first and be prepared to make some phone calls for tech advice. If your father has rebuilt auto's before and you guys have all of the necessary tools you'll be fine. Don't expect to throw 1000hp at it, but I don't think that's what you had in mind.

He has rebuilt a lot of trannys before I'm only wanting to make about 550~600hp that being said what kit do you guys recommend and I'm not gonna beat it up to hard I don't drag race or sled pull just in a dd street truck

[PACougar]

Sounds good just don't want a failed costly build that won't hold

Have a builder do it. There are no guarantees.

Honestly shippings not that expensive. They'll send you a built transmission for your needs.

Yeah I'm planning a trip to see me sister she lives about 25 miles from the shop in ocean city fl so I could drop it off while I'm visiting

 

[PACougar]

That's a great choice.

As long as I can afford it haha I might just have to back the tunes down and settle with it for a while
