just looked up my tracking number, my converter should be arriving at yank on thursday next week. don't know how quick they jump on things around there but maybe sometime monday or tuesday the following week i'll know something. And Yank, I'm probably gonna be pretty busy around that time so if i dont pick up on either phone line i left on the original invoice below my address, just leave a message and i'll call back first chance i get.
Yank is a good company , i would not sweat it one bit!
I know from experience that the company backs their product,i had a SS4000 after about 15,000 miles i started having a issue with it not locking. i found material in the filter and called them after talking to my transmission builder.
They asked me for the vertor back and found the lock up clutch had a issue with a small bit that had com apart,causing a issue.
It was covered under warranty and all ended well.
Now i have a PT4000 and just started having issues with the convertor not locking up. It could be a convertor issue, but i am going through all other areas of my car first(tran,mechanical,tuning etc.) But it is odd that i have about 15,000 miles on this vertor too and a lock-up issue is happening.
I really like the way the PT4000 performs ,above and beyond my VIG3600 and even better than the SS4000 . I am just tired of having a loose convertor that will not lock up.
It cost me over $450 to prove the trans ,electricals were not the cause the first time around.
Once the stock vertor was put back in , i had no more issues.(Also no more fun
)
Good luck,post up what is going on and pray for an early spring so i can start driving my car again

well Dave got back to me early today and told me that the clutch was burnt. he said it had to be locking in order to have burnt it up like that. it was at first but quit like i said. he thought i may have a crossleak in the pump? dont know if i'm sayin it exactly right, but anyway he's puttin a new clutch in it and sendin it back so he did me right and i'm happy with that. picture of the clutch is attatched.

I had a two aussie hi stalls burn and drop their clutches clogging the cooler, got the check engine light due to the heat in the tranny I suppose,
I had lockup in third disabled and 4th lock up set at about 60 mph, thinking among other things it might have been locking too early before..
Have the Yank Py 3400 now and its all good except found the snout that drives the pump cracked for some reason, gotta sort that this week, while the tranny is out being modified again.

Yes, the torque from STR ratio that is seen by the stator shaft will twist the alum pump housing and can allow for leakage between the halfs as this happens it also loosens the torque on the bolts that hold the pump together
and the Yank converter also has a larger clutch with more surface area that the other converters out in the market and needs a good supply of high pressure oil to hold it in total lock up
this is common with the alum cast front pump used by the 4l60-e type of transmission, a resurface and rebuild are requiered during the rebuild process of any 4l60-e transmission due to this problem area

The 4L60's are touchy. i ran a yank 4400 and i would loose lock up alot on the street. I deff dont blame the converter though, do any of you guys have trans temp gauges in your cars??? It would be a very good investment. that way if you loose lock up anymore you know when to draw the line and pull over, a 4000-4400 will get a trans hot real quick!! Ive buried mine at 260* a few times, thats with an aftermarket cooler and fan and BnM deep sump pan 
ive always pulled over and let it cool down though. that kind of heat will burn up clutches. not pointing any fingers though just some things to keep in mind.

I guess if what you have been told is true, your tcc should be shot within the next couple days. I wounder if it is possible that the converter could of developed a crossleak. I will have to ask that question to Jack or Vicki the next time I talk to them. Vince

My car has a P0757 code and it goes in and out of limp mode. I need to change the damn shift solenoids and see if its that but i know a tuner will have to delete the code. I'm getting tired of having to pull over and shut my car off for 10 seconds and start going again laol. So Jasson you had the same problem we are having no lockup at all untill you started having someone tune it?

damn, reading all this has got me worried
my Yank 4200 wouldnt lock from day one, my tuner checked the file, everything is set right, he talked with hp tuners and verfied some things, no lock up, we can manually lock it while your driving with the tuning machine. only hope i got is the trans temp sensor is saying i have a -36 degree trans fluid, so hopefully i can find out whats wrong with the trans temp sensor it will lock up for the first time.
