There 9"? Is that the only way you can tell they are the single disc? My stock 4.6l isnt PI so the converter shouldnt be.

 

Actually, my trans came out of an 01 f-150 so it would be a PI converter... I need to replace it then with what year and engine converter you think JL?

 

No,no..PI=Precision Industries in this case.
The only torque converter that they make that's worth anything is the multi-disc,and it needs work after you get it.They use a crappy clutch material that fails and flakes off clogging the fluid passages in the trans. The stock torque converters in F150's are a 12".

Really, I hear wonderful things about thier vigilante line? Perhaps factory tech would be the way to go anyway.

 

At one time PI made a good converter. But with the introduction of the lockup converter-they just didn't think about how the high HP cars would literally destroy the wimpy little single discs,so they had to back up and redesign it as a multiple plate lockup clutch for high HP applications. Problem is-they use what I consider to be the crappiest clutch material that's made-clutches in stock converters are stronger.
The other problem I've seen out of them is lack of quality control,and hackjob methods to get stall speed.
Personally I refuse to buy anything from Factory tech. Greg goes on and on about trans building like it's a black magic voodoo art of some kind when it's not anything like that. Deceptive practices in marketing a product gets me very irritated-I despise an unethcial vendor that sells product based on customer ignorance,and IMO-that's what he does.
