Torque Converter help

[cfitz]

I'm looking for some technical info on the specs of a torque converter. Per VIN, my truck has a 24217235 GM part # in it, can anyone tell me the impeller hub dimensions of that part #? I need to know if its a 2" or 2.5". I can't seem to find anything and the local GM dealer doesnt have that info... Thanks in advance!

 

 

Edit- figured it out, its a 2.625 impeller hub height if anyone comes across this issue

Just curious, what was the issue that required that measurement?

Apparently GM has two impeller heights. The company I called asked me for the measurement, the 4l80e can come with either. It is a pump interference thing, if you try to put it together with a 2.625 when it requires a 2", you could destroy the front pump and if you do it opposite, the converter wont reach the flexplate....
