Some quick help please

Thanks for the advice, that's exactly why I asked for some help on here. I want to fix the car right the first time, and not have to deal with this issue again. I'd much rather spend a little more upfront, than have to throw money at a rebuild later on.
I'm sure others will chime in too. I completely understand wanting to get it right the first time. It's not much fun taking that trans in and out. Hope that helps.
