Default 4l80e Front Pump Mods...

Hey guys...

I'm looking for a picture of where to drill the front pump... I was told to drill from the pressure port to the converter charge port.... helps prevent converter charge loss during full line pressure situations.

Has anyone heard of this or have a picture showing where to drill?

Thanks

NVM... after reading through my ATSM and looking through the instructions for the trango shift kit... the same mod is done in that kit.

Thanks anyways
