I have a older model stall that I traded for to possibly use or resell. I have a 2000 trans am 4l60e, ls1. I was wondering if i could make this stall work on my car, I really love yank converters and was going to send this one to get restalled if i could make it work. Here’s a picture below, if i need more info let me know kinda new to this transmission stuff
*edit
I remember seeing somewhere that it has to do with the flywheel, but not sure y’all let me know!

Yanks website doesn't show any information on "ST3500 LT1".
First you need to identify that converter. Is it made for the LS engine's 300mm input or is it made for a 298mm input shaft.
I would give them a call. If that's a date code. 09/01, makes it 24 years old.
I'm going to guess that the "LT1" indicates it might be for LT1 engines, e.g. 298mm input shaft and therefore completely incompatible with an LS1 300mm trans.

That's my guess too, just figured it's better to hear it from Yank.
ST series was their "Super Thruster". This was an NA converter that offered a harder hit (higher STR) than their "Super Yank" (SY) series converters at the same stall speeds. SY was more efficient but softer off the line (great for street tires, I loved mine).
ST was very popular for street cars before they introduced such current models as the SS series.
But yeah, it seems certain that this one is for an LT1.
