The tranny won’t go into any gear after a 4.5k launch. It just stays in neutral. The controller does display R, N, D, 1, and 2 but does nothing. This was my second time testing the TB. I’m using the Quick 6 controller. Car launched, bogged down and I let off immediately. There was no breaking noises at all. It just smelled like burned oil...and for a reason, cause it puked some but it stopped. What could had happened? A seal let go? Fluid looks like it came out of the inspection cover.

What does the fluid look like on the dip stick? How much came out? It's possible it blew enough out that it can't maintain pressure anymore.

Fluid doesn’t look bad and it didn’t leak that much. Probably a 1/4 of a quart.

US shit tech support leaning towards molded leadframe failure.
