If they move without sticking then they're good. Some valves can't be checked without further disassembly tho. That is an extremely tiny 1-2 shift hole, so you'll see lots of improvement there.
Ok cool I'll do that, I also found instructions for a B&M kit online would it be a good idea to drill the other passages too?
Also the part about installing a 1/4" check ball inside the spring on top of the 1-2 shift valve, I could use one of the extra 1/4" check balls I now have from the old valve body would that be a good idea? What does that do exactly? In these instructions it says to do that for "off-road racing applications only" but a TCI kit I found says to install the check ball for all applications...?
