I just had a guy ship me what he thought was a VP converter.. delt with him before, and I am sure it's just an honest mistake, but it made me realize that we don't have a visual ID Thread for the Variable Pitch pumps and converters on the board here.
So I took some pics..
Fixed Pitch Converter T-400 Stator shaft (part of the front pump) VS. Variable pitch
Here's the Fixed pitch stator shaft:
Variable Pitch Shaft..
Converters - Fixed Pitch VS Variable Pitch
Fixed Pitch- When you look down the hub, all you see is the Stator splines.
Variable Pitch- Looking down the hub, you see two bushings with a space in between, and then the stator splines. This is true of both the 12" and 13" VP converters, and no other converter will look like this.. This is positive ID!
12" VS 13" VP converter ID
Close up of the 12" measurement..
Visual ID- Converter Cover
The 13" converter will have recesses to mount up to 6 mounting lugs-
The 12" unit has provisions to mount only 3 lugs
Now you can Field ID both the VP trans pump and converter, as well as tell the difference between a 12" and 13" VP converter.
For you junkyard hounds.. print this out and throw it in your toolbox.. I actively purchase any 12" unmolested VP converter I can find. I pay $75, provide the box and pay for shipping, for a good 12" core (can't be a Poston (PAE)) unit, this offer only applies to a stock, untouched core. These cores are located in ST-300 two speed transmissions, in various 64-67 GM A bodies. I have also found them just laying in a "converter pile" in a junkyard in the past.
I will ship you a box, plug and return lable along with a check for a good 12" VP converter.. all you have to do is take out your check, plug the converter and stick the Shipping paid lable on the box, and take it to a UPS shipper.
