So the complaint with that "pink" (Vigilante) Converter of mine was that - something was rattling in there and I noticed that the stall speed had changed making it substantially "looser" and to tell you the truth - I was NEVER happy with this converter from the day that 800 dollars left my checking account. It never stalled right - when I first got it, all I could "squeeze" out of the 0-Pump stall configuration was 2800 when I had the laptop connected and my foot on the brake and squeezing the shit out of that thing it would max at 2800. Not happy. Back on my back on my garage floor dropping the trans again, and had it changed to a 6-pump - which proved to be better - yet not very long lived.
The NL Converter I got from Lonnie years ago worked better than this thing - yet I wanted to make a change cause I had a history of pushing front pump bearings forward and cutting the front seal. I found a nice front pump bushing with a "shoulder" on it - yet this was after a couple of incidents - and it was at that time I went back to LU with this pink converter.
Remembering the old saying, "If you do what you always did - you will get what you always got". Hence I decided to not send this thing back to Precision, and per Bulletin Board Members and a good discussion with Dusty, I sent it off to him. He cut it open and examined it, and his assesment is as follows:
---------------------------------
It's been cut open. The liner was burnt indicating the clutch has been slipping. The major issue was the fins in the pump had broken loose which will make the converter very loose. It started out as a converter I would rate at 3400-3500 at 0-1 psi which is very loose. We need to replace the pump due to the broken fins so I can put a pump in it to make it closer to a 3000 stall. Do you feel it was to loose to begin with? The fins being broken can cause a rattle. They will also cause the stall to be higher than normal.
