Installing TransGo TF2 kit. Is there any advantage to not taking hole C in step 1 on page 1 right to .187?
Would smaller help reduce potential 2-3 shift overlap and eliminate the need to restrict the feed to the front clutch?
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

I always drill them out to 3/16" (if smaller) on the premise that it's easier to drop the VB and install an orifice restrictor in the case if needed than it is to pull the VB and disassemble it.

Thanks guys.
I’m setting this up @ 12 springs in the front clutch, .073 clearance, 3.8 KD lever, solid band, early kick-down servo with 2 springs, and the TF2 set up to all of the advised “race” settings, with their supplied restrictor.
4 clutch forward drum. Valve body is a 73 valve body. TA 3500 stall converter.
Any feedback on if this is likely the right track or if I’m likely to have an imbalance causing too much overlap?
Thanks

i'm thinking i would tap the hole where the restrictor goes in the case to 1/8npt. the hole is already the correct size for the tap. then get some female hex pipe plugs and drill several different size holes in them to get the results you want. just make sure the holes are tapped deep enough to allow the plug to seat below the valve body sealing surface.

I did this mod to mine last week to replace the existing stamped restrictor plug w/ a threaded one drilled to the same .14" orifice.
