This converter is 12" on the outside, and the inner converter section is 10".

It has the numbers "78396" on it and a sticker that was painted over that has some numbers and a barcode on it.

It fits a 4L60E.
Any suggestions to identify it?

 

Same design as Lashway advertises, except theirs are purple. Maybe someone painted it black?? Hope your not planning on using it.

 

The whole build was only a thousand miles old before the truck was totalled. I want to send it back to the manufacturer to have it inspected.

 

Thats a PATC converter.

You might consider reading up on 'spaceship' converters. It was an early attempt to get a decent sized clutch in a 9.5" converter, the bad part is the weight and lost efficiency.

Now most quality converters are using billet fronts.

The barcode sticker is just a left over from the original 12" core. These converters are made from 12" cores for the front and 9.x cores for the rear.

 

I am 99% sure that Midwest manufactures those for PATC. I bought one from PATC back in the day and I bought another from Midwest about a year later and they were identical. I had good luck out of them, but that was back when I was around 350 rwhp. I would go name-brand with anything over that power level....
