ats banging down shift 2-1

[dirttymaxx]

ok,we have a ats (bad word) i know,and it's banging the down shift from 2 to 1st. we serviced the trans about a week ago with a new spin on and new filter,and fresh royal perple fluid..still doing it...

this trans has a total of 4 years on it and two of witch have been some hard sled pulling...

whats your thoughts?

i got a feeling i know what everyones going to say,it needs a rebuild etc...just thought i would ask before we jumped right in and done it


also here are pic of what we found in the pan when we serviced it

 

[Mike L.]

Time to pull the trans.

 

[MACKIN]

Is that the first time in four years you dropped the pan?

 

[dirttymaxx]

yep 1st time in 4 years...that the pan has been off...but not the 1st time the fluid has been changed or the spin on

yeah MIKE L i didnt wanna here that but i already knew that was coming....

MIKE L send me a pm with the cost of a rebuilt kit etc phone number also

 

[MACKIN]

IMO that isn't a whole lot of debris for 4 years. Just saying

Since you aren't staying ATS on the rebuild I'd like to know what it will take to convert a Purple built transmission to a Suncoast style conversion. ATS does not use a Transgo and make different changes to the valvebody and who knows what else. So what is involved?

 

[dirttymaxx]

^^^^^^^ X 2

i was thinking about just pulling it down and putting clutchs in it...if i cant find out what to change...imo i think thats the best opp seeing as how pulling seasons has started already...

i can do that for about a grand,but whos to say the tc isnt tost as well...
cuz ill be the first to tell ya im no trans man...

 

[MACKIN]

If the TC isn't replaced at the time of rebuild IMO it should be sent out inspected and or flushed. Has to be cheaper then replacing as long as your satisfied with the one you have.

Just replacing clutches would be reasonable in cost . But can you just buy Alto's? Mike needs to chime in I've never been in side a ATS transmission,if he would. He has had to of worked on one previously so he'll know.

Come on buddy I've been curious as to what is involved.

I smoked my trans and my converter after 4 hard years and I still had less material in the pan than that.

A friend of mine built an ATS Stg2 for his LLY a few years ago, IIRC it came with an all new C2 drum instead of modding it like the transgo, also has new backing plates and apply pistons so I don't think you'll be able to run regular Alto power packs, but then again I'm no trans guy either :thumb:

 

[x MadMAX DIESEL]

Mine does that too, and I was always told that its normal, "nature of the beast". From people on here even

 

[Righteyeblind]

The alto clutches will not go in to an ATS trans and be right. Clearances will be way off.

I hear you but for ATS clutches that's clean for four years! :rofl:

That's what I'm saying. My thought was you are better off using it as core by the time you gather necessary hard parts but I'd like to hear Mike chime in as I'm not 100% sure. A new plate for the valve body can't be that much it's mostly what mods are done to c1 c2 drum. If you could get pistons and backing plates as a kit with the clutches then it can't be that bad.

Maybe we stumped him! :roflmao:

Have you reset the taps, done a fast learn, and checked the psi at the port?

The only difference I found in my trans with a ATS stage 2 is a stepped HD thrust bearing and a machined p1 drive flange for the extra snap ring ats uses. I also called ATS and one of the builders confirmed that's all they change.

 

[IOWA LLY]

The port is beside the spin on filter. Since its an ats trans you will probably have around 315-325 psi at 1800 rpm. You can also reset just the taps for the 2-1 downshift so you dont have to re-learn everything.

Thats odd, was it a kit or built by them? Maybe he built a Stg3 but I thought the only difference was the co-pilot.... My buddy (Colin) had bought a kit from Crankitupdsl.

Crankitup did mine. The only difference between the stage 2 and 3 is the co-pilot.

 

[Evan@InglewoodTrans]

It was a kit.

I'll have to ask him again, but I remember him asking why mine didn't come with a new hub when I installed the power packs
