Th400 converter turbine locked up
New fti sst converter decided to lock its turbine solid for reasons beyond my comprehension.
wasnt doing anything drastic. Drove 3 miles, then wanted to test the stall so put it in 3rd (manual valve body), break stalled it, got some boost built up like 7 psi, let the brakes go and rolled in the throttle.... with street tires that made for a nice smoke show but within second of letting the brakes go, it was game over. Came to a stop, motor stalled out like when you forget to push the clutch on a manual.
converter is out, can confirm i have no turbine rotation in any directions.
Stator moves as it should, smooth (mechanical diode).
sparkles in the fluid out of the converter so looking like a full trans fluid change, new screen and flush out the cooler is in order... yay me... trans has 200 miles and brand new (stage 4 fti).
anyway.... anyone knows why it would do that?

S happen but that trans is brand new to (200 miles)... one of your stage 4... hope it's ok! (I think it is but will pull pan later this week)
I called Monday am and sent it out ups on my dime that day. I can't recall whom i talked to. As an aerospace engineer i am really interested to know what went. My educated guess would be something like a washer or Torrington bearing not properly hardened from the oem or maybe the tolerances went out after welding.

Can I offer some extra FTI merch like a couple shirts or a hoodie in exchange for the freight you covered? We'll know if the transmission needs to be looked at after we cut the converter open. Based on my suspicions I think the transmission will be ok. but if it does need attention I will make sure we take care of that for you too since it is one of our transmissions.
