I wish my 4t65e fit in a bin…well, all the parts BUT the case fit. I have 3 bins full of 4t65e trans parts.
I originally received my trans from the shop that built it, on a pallet, banded and plastic wrapped. When it broke, I put it on a pallet, banded it, and sent it out. I got it back the same way they shipped it originally. NO problems. BUT, I’ve bought to engines that have been shipped to me and BOTH times I’ve had something break off…ign. coil nub, and a valve cover cracked. I think its just playing the odds and hoping they’re in your favor.
