Good Day,

I'm trying to confirm if my TC is installed correctly. During installation I heard two defined clicks instead of three200969200970200971. But it seems it is very far out from the underside view.This is my first swap of this kind and don't want to ruin this built transmission.

Who made the converter? I would call them and ask. From the looks of it, I think it needs to go in more into the trans.

I will do that. It's from TTC (Total Transmission Chicago).

Below is from his website:
How do I know the converter is completely seated?
The old “3 clicks” method is not an accurate way to determine if the converter is correctly installed. There MUST be clearance between the converter and flexplate when the trans is bolted to the engine. In a perfect world this would be 1/8″ or .125″ everytime, and you just bolt it up and go. In the real world, we have to check it and make adjustments as necessary.

On a typical GM engine, the flexplate mounting pads are 1″ away from the bellhousing flange area of the block. The converter pads when seated completely will be approximately 1 and 1/8th inch ( 1.125″)recessed into the bellhousing. Seat the converter, then measure the distance from the engine block bellhousing mating flange, to the mounting pad on the flexplate.

Then do the same from the transmission bellhousing mating face, to the converter mounting pads. You should have the converter sitting deeper than the flexplate protrudes from the engine. If so, you can now bolt the transmission to the engine. With the trans bolted to the engine, you should be able to turn the converter freely. Check the distance from the converter to the flexplate with the converter completely seated into the transmission. You should have 1/8″ to 3/16″ clearance. (.125″-.187″) If it is more than 3/16″, you should use flat ground washers to shim between the flexplate and converter.
