LB7: Allison 5 speed to 6 speed conversion

[sam_rork]

Thinking about building my 5 speed transmission to handle my current modifications to my truck then ran across the 6 speed conversion kit. Would this be the better option over a built 5 speed tranny? I’m mainly looking for fuel mileage On the highway and not tearing up my tranny when I want to have some fun.

The 5-6 speed conversion will not allow you to put any more power down without building the trans. If you need a built trans to handle your power then build it, if you want the 6 speed then add the conversion to the built trans. Then you’ll have both.

I just did the 6 speed conversion in my 02, should have done it 10 years ago.

Thank you that was my next question. I think that’s the route I’ll go. Conversion then rebuild.

You're doing this backwards.

X2, make the trans hold the power, then do the 6 speed conversion. The 6-speed conversion doesn't require removing the transmission, just the valve body, and can be done fairly easily at any time.

It is also possible to build the transmission and do the 6 speed kit at the same time, and you will save a little bit on labor this way. That is what I did in my Suburban.

What would cost be for building the 5-speed? I believe for my mechanical abilities I could do the conversion kit but how intense would the rebuild be for an individual that doesn’t work on Allison Transmissions every day be?

If everyday means that you never did rebuild an Allison and you might have the ability to bolt on a valve body , you might wont to contact one of the great transmission guys on this site. Unless you love a challenge , then go for it !

Ok I do not find this comment very helpful? He is wanting to know if you do a 6 speed conversion. Can you then rebuild it as a six speed? Because a 6 speed rebuild is a lot cheaper then a 5 speed. Again looking for help not sarcasm. Thanks

There was no sarcasm posted. Who ever told you that a 6 speed was cheaper to build than a 5 speed?

Conservatively $5-6K if you have a shop build it. LOOK IN OUR VENDOR SECTION for MikeL (Inglewood Transmissions) or Evan (Limitless Diesel Perf) for their phone numbers and call them about your options. Evan sells a kit if you want to do it yourself. I am not sure if there are any competent shops near you to do the build.

How about you do some searching and reading around here before opening your mouth? "The guy in sheeps clothing" is MikeL. So torqued's post was helpful.

So then explain the Statement “The guy in sheeps clothing” because that was very confusing and misleading to us that had no idea what that means and for being new to this “Tapatalk”. But thanks for explaining who it is and about the “Vendor Selection”.
