if i remember correct, Buck told me when i asked him about the duraflite on the raod that it can be done but would not be as good as the allison due to gear ratio. now i cant remember if this was for the 6spd only or both.
In the end it would be to each their own. I have yet to hear an allison shift on any truck running low 10's or high 9's like one does with a duraflite. This debate will go on forever. I guess once the allison runs as fast as one with a durafilte then the argument can somewhat stop. I mean max effort to compare. Maxed out ran 9.70's in Topeka as clean as a stock truck running down the track on one pass on dot tires. Buck has ran 115-117 mph in the 1/8th in the 6.0's range. Neither of these have been ran all out yet this year. As far as holding hp that all depends on the build of the trans too. Has anyone ever sliped a fully built trans on a dyno holding in one gear? Most problems are during a shift. Like Osubeaver stated...if neither will last, might as well get the most out of what you got.
Also is it just me but swap the converter is what 400 plus s/h
you can replace Worn clutches for that.
J Spruill;396169.. trying for 5s on fuel then gonna spray it again...[/QUOTE said::beavisnbutthead::yourock:
true but this assumes you can rebuild you r own tranny.if not its much cheaper to send off a tc con for refresh than a tranny fir rebuild. whatever works best for the situation i guess....
I don't know anyone running 10s or lower that doesn't either do there own work or have a freind that knows how to replace clutches
we ship em to suncoast from nc...
Hi my name is OSUbeaver.
My trans was shifting great the last time at the track 7 passes all above 140 mph
Jmo but from many friends that are hardcore gas drag racers and telling them I want the best trans and then tell them I want to build up a oem to handle this....... I get this look:screwy:
I also ran 117 in the 8th I don't see what that means?
Yes I like the tall gears and it sounds great but I don't buy parts based on how it sounds
A gain in et can be simply from weight reduction... Something to consider
and yes my truck is very streetable just like maxed out is

Jerry got a manual valve body and shifter when he bought his duraflite, I'd really like to see how it would do drag racing, shift light and shift like the gassers. Would be interesting.
Well if you have ever driven a full out big HP dmax with both then the decision would be easy. Yes both will break, yes the Duraflite likes it's TC changed about every 20-25 passes. You will cut about 2-3/10 at least off your et by going to a Duraflite. We raced one last year all year without issue. This year we have had problems, mainly with the TC. For a full out, yet streetable Duramax I think it's a better option. Look at the quick 50 list. The first 5 are not even real trucks, #6, 7, 10, 11, and 13 are all Duraflites and the last two are just getting started. I have an Allison in White Out. It ran 10.7 with a tranny that was flairing to over 5000rpm on the shifts. If I had a Duraflite in it, it runs 10.5's easy.
If I were starting out and wasn't trying to make a low 9 to mid 10 sec truck, then I have an Allison. If I did and and still wanted to street drive the truck a little then it would be a Durafite.
Well I commend you for hanging with the Allison. You had all those passes over 140 and still in the 10's. Switch to quicker shifting and lighter tranny like the duraflite and get into the 9's and be an instant 100 lbs+ lighter. If Mike L or Big Dipper can get one to shift like a duraflite I hang in there. I just don't see it happening. Too much stuff going on in the shifts and the computer way too smart for simple dumb ass drag racing.

Paint we are still waiting for your explanation of why you are so troubled by the duraflite controller? Inquiring minds want to know.
true, but i really believe we are knockin down the doors on what a allison can do and do well in. Wasnt long ago the alli couldnt do anything near what they are doin today. IMOP and from what i have seen and gathered, i dont think the duraflite has much more to gain in technology or major progression in the sport. though clutches can get better and/or TC's but I think the allison will be the way to go down the road as due to how much computer control there is. I dont know if the duraflite has as much computer control as an allison but with the speed computers are reaching now a days and tuning software that is continually being updated, i see the allison becoming something of a contender in teh next few years. we have already seen the progression of clutch packs and how they have improved over the years, now its what can we do with tuning and making the computer faster and more knowledgable
This is all form what i gathered and could be completely off base but i dont think the allison has been put to its full blown potential yet in a drag truck........IMOP
