"Built" Allison longevity?

[Mike L.]

Sometimes they're tuff. You have to line up 2 sets of spline and the pump lugs. Sometimes billet shafts are tite if you're using one.

What would make it so hard to get it to seat?

its not hard, DONT force it...it just takes some "finesse", I guess thats the best way to put it...the first time you put a converter in an allison you'll probably screw around with it for a minute or two before you get everything aligned so it drops into place (or you might get lucky and it goes right in)

I use that term too often nowadays with careful, slow stuff lol but I gotcha

I always pull the converter right after I lower the transjack, and set it in just before jacking the trans back up. The only problem I have had doing it this way was getting my finger caught between the converter and bell housing when it seated once..... It didn't feel good!!!!

I'm gonna pull my tc when I get back in town this weekend just to see how hard it is

Never had good luck with the ATS trans myself through the many, many visits to Clints. Scraped it. Only trans I've had hold up is the Mike L. special. Still holding up good too. 45K of serious poop thrown at it. 1057 converter holding the Mike L. special.

I noticed mine was harder to stop in 4 low when I installed the ML Precision converter. Not bad just had to press the brake slightly firmer and I am used to it now.

My ML definately has a good bit of bite to it in 4LOW, so much so I have to go to neutral before park when in 4 low because it torques the bURB enough that if I don't I get a NASTY ratcheting sound when it unloads the driveline and engages the parking pawl(it also throws a VSS code when it does this). It's manageable, but you will notice a difference.

This concerns me a little...Is there anything that can be done with EFI-live about this short of lowering the idle a little or is that a bad idea since the LLY's seem to have a low oil pressure at idle anyway? Or is there a converter that doesn't have such an early bite?

Waiting on production now.

Looking forward to seeing what you come up with Mike! Thanks for what you do here.


Thanks for all of the input too guys!

Lowering the idle to 600 is just fine, and is pretty easy to do. It helped ALOT on mine.

 

[DieselS10]

Sweet, that should help a lot. Not being able to stop it, short of throwing it in neutral, doesn't appeal to me since I have a tendancy of driving it where it probably shouldn't be, lol.

"comparatively", yes, its easier to get the converter seated all the way with the trans standing vertical. It would probably be really difficult for someone who has never done one before to get it seated all the way with the trans sitting horizontally...but after you get the practice of doing a couple dozen of them, its no harder to do it horizontally vs. vertically.

just when you think its in.....it still has to go deeper

On the longevity thing, the only thing I have heard (from Mike) is that running REALLY high line pressure will cause the C2 steels to beat up the input drum. Dunno if that shortens the life of the trans, but it might require a new drum come rebuild time

So, I'm going to be using a stock DMax converter with my wimpy motor. How does it "creep" in low range compared to the ML? I'm going to have 4:1 low range as well.....

Wendy's is 5 1/2 years old with 70k plus miles on it. But everyone knows I drive like a girl :roflmao:

Blue's is even older then that.

Casper is a guinea :mikelsheep: :woott:

All only touched be Mike L :hug:

Another thing I noticed was I ran the 6 speed C1/C2 drum for about 2K miles, and when I pulled it down it had a noticeable amount of wear from the C2 steels riding inside of it. My 5 speed one with the PTO ring gear on it had virtually no wear inside of it after 20K miles of driving. SO I think the C2 wear also has to do with which drum you have.

Tim built my current transmission in the spring of 09, its a gmax kit, it has lasted through 11 and 10 second passes, and 2 years of sled pulling, it will be seeing a 4th season. Ive went through quite a bit of converters last year though. Im not blaming suncoast one bit, im not sure any converter will last long with 1-2 minutes on the line trying to light the turbo. There was quite a few times the paint was boiled off the converter, they usually lasted longer than i thought they would. At the end of the year we got the stall time down, and they seem to be holding up great.

Any special tips or tricks in your trans? Or just a regular "off the shelf" kit, installed just like it says?
