Inspection of a 904 torqueflite

I’m definitely sure it’s a 904. It even has a drain plug in the corner.....nice.

It’s a heavy fully loaded custom van. The 318 has the 302 heads I just took off of it. It has a single wire coming out the back near the tail shaft.

I looked up a part number and got a random website identifying it as a 999. A van like that would need a trans like that.

I checked the differential.....it’s running a 2.90 gear.
I’m guessin it is....l

But that number would tell all. I could use a 999 and want a lock up clutch. It’s basically,y what I’m doing sort of anyway. The trans is $100
