tore it all down and started back with the corvette servo, it has you cut four oil passages in the plate I started out with a large file and cut small squares in it only to find out they were covered by the snap ring when installed so I broke out the flap wheel and opened them up and still barely clear the snap ring but I didn't want to cut out the bend fearing I would weaken the plate. installed larger boost valve in the pump (very long nosed snap ring pliers needed to make it easy). Drilled the separator plate all directions was clear except for the 1-2 shift hole stock its drilled .065" but said it could be drilled to no larger than .073 well the kit does not come with a .070-.073 drill so I found one that was just barely larger than the factor hole and went for it, cleaned and replaced springs in every piston in the valve body, installed all the pin less actuator pistons, this is where it kind of got confusing,
Transgo gives one set of instructions and Sonnax gives another when it comes to how the pistons should be set in the bore....I installed it the transgo way and hoped for the best.
The transmission gasket was baked on I used the flap wheel on a 4" grinder to remove it, buttoned every thing back up (less than 12hours total) and waited a day to put fluid in it still thinking about those piston discrepancies.
Then went for it, filled it, stuck it in revers and to my surprise it went the direction it was supposed to. I cycled the shifter a few time and filled to level and took if for a drive, pulled out of the drive and when it was supposed to hit second it held for about 1-2 seconds longer, I was ready for the hard shift(remember the .073 hole I guessed on), and it shifted super smooth and crisp. So now I'm thinking what did I do wrong it was so smooth. I ran it all the way up highway speed and every shift was smooth but crisp, I stopped and pinned it to the floor, spun just a little and when it hit second this time at 6 grand it knocked stuff out of my tool box but didn't bark second (I was disappointed). I stopped and did it again, and again and again...LOL the only thing I noticed after all those hard runs was the 1-2 shift is hard but almost feels squishy like when a leaf spring rear axle is twisting the springs. Today I took it out in the rain and did the same run it shifts hard enough to break second and jump side ways... I will take it for a longer drive this weekend up in the hills to see if I burn anything up.
