Here's a photo of the new Jake's converter on the RIGHT (black paint). Disregard the left one, it's the old 4L60E.

This is what the snout looks like, it has 2 flats machined in it.

Update – it runs and drives! Currently NA with the charge piping off to shake it down, it’s a dog since I have the turbo timing (11-12 degrees) in it right now but I’m just happy it moves under its own power.

Picked up the trans from the shop with the Rav4 2500HD




















Immediately loaded it up with junk to take to the scrap yard



Turns out one of the valve body gaskets had shifted when I installed the HD2 kit and it was blocking some passages. The gasket had some impressions where check ***** had obviously pushing into the gasket material rather than the hole in the gasket, resulting in massive internal leakage. The shop confirmed that the pump looked fine and clutches looked good. Although it wasn’t fun to pull this thing out a couple times, I think it was worth it to have a pro go through this $200 80E and give it a clean bill of health.
