it’s cast iron,...so no. Besides, way more of a concern are the imprints the spacers left inside the front pump.Can't you TIG the hole closed and redrill it, using the proper bit?

and even if I could...there’s that.
Heat = warpage = vibration
It's a GM transmission, until 2007 they were all low tech AF.Cast iron? That's low tech AF

Gotcha.i am talking about the 4l80, i was also stating a fact for those that think cast iron is a GM only metal.
I have a different pump coming, I have new bushings, gears, and seals coming. I'll go buy several .042 bits so that drilling the one hole will be possible, as there is no counting how many of them tiny assed things ill snap off.Chuck the pump, buy a new pump. This time buy the correct tool for the job!
I'm not sure there's anything like this that would be sufficient. These look like something you'd get with your ikea desk. I think I would install time serts or helicoils. Every time i look at this pic. i cant believe they used those...I don’t know much about T nuts. Can they be had in a hardened version?
