Allison refresh
- Thread starter Jakemax04

Are you talking high horsepower allisons or what?
If an allison has a lot of power ran through it then you can sure bet it will need a refresh about every year/season.Sometimes more often depending what it is doing.
Other guys rebuild there perfectly fine stock trans simply so it will handle more power.
Other guys refresh them simply because there worn out or damaged.

From what I have read it seems a lot of people do it who have built motors. But I'm wondering if it's performing fine why would you want to tear it apart? Or am I mistaken in thinking people do it before anything is broken? Personally I wouldn't want to have to take my tranny out unless it wasn't performing
It's done for what it means to "freshen" it up. When under a lot of stress clutches and other parts are going to wear or weaken. In addition you want to look for any potential problems that might be happening unexpectedly when you want the transmission working at it's peak performance. No different then a motor with drag racers in the gas world
I have over 200,000 miles on my suncoast trans since I built it myself 8 years ago...never had any problems and dont intend on "refreshing" it unless something happens.

I should have mentioned those with daily drivers aren't going to do anything unless it breaks but those that are competing semi or professional are going to be the ones doing the freshening.

Ya but everyone knows that you aren't really putting any power down to the ground through the Allison! You'll wear out 10 batteries testing your Gizmo's before 1 transmission! :thumb:
I don't know of anyone who is going through transmission that are working perfectly unless they're in a race (or mostly race) only application. In something like that it's a good idea to check things out in the off season (or between races) to make sure you don't have a problem developing. You don't want it to let go in the middle of a race when you could have prevented it by doing a little preventative maintenance. At big power levels, these things don't live forever.

my white trucks trans has been perfect all season but its on my bench right now for me to open it up and see how everything is looking. in hopes that if something isnt liking life, i can address it so it wont fail during a race 2000 miles from home.
now my black lbz DD truck, unless something fails i wont pull it out just to check it lol

That's what I was looking for lol! Those were the good 'ol days...

Just curious josh at what good power level do they live the longest I understand the variables of it, is daily driven is it wot all the time and so on..... But where do they tend to last the longest? I've heard that sled pulling trans usually last longer than drag racing because there is more stress trying to make 6-7-8000lbs move 9-10-11-12 sec in the 1/4 is harder on them than most think. Just wondering thanks in advance
I have a 04- LLY with 100k miles--PPE running on 2, and driven like an old man-- "cause I is".
I just had Mike :hug: go through the trans [no problems], because I want another 100k carefree towing miles out of it. Looked good inside, but the C3 were really worn. Maybe from the stress of the 6 speed conversion. Just got back from 6k mile trip and it worked great.
If the clutches and converter disk starts to flake, and you continue to drive it, That can send debris through the system; clog filters and cause valve body problems.
