It has the TF-2 kit. I will pull the pan and rear servo and make sure that the heavier spring is there. And I can drill the piston, too.

Is the #40 drill the largest that should be used or is it a starting point? In order to clean up the 2-3 overlap, I ended up pulling the valve body 3 times. I tried a .010-.015 smaller orifice each time till it cleared up. Could I do the same thing with the rear piston? Start with the #40 drill bit and go up .010 or so at a time till the shift responded?



What year is the trans ? If pre 70 maybe get the valve John mentioned and possibly tweak the passage, or switch to the later VB ??

Drilling the hole bigger and bigger till you fix the not really a problem may cause a problem ... allowing the band to slip in reverse, reverse doesn't have the sparg helping to hold the drum ...

Just a thought .
