Do I have this right? Hey guys, after researching and reading and watching videos, I just wanna run some things by all you guys.
Building a 4l60e going in a 2002 Yukon 4wd, has a freshly built lq4, 11.5:1cr, 218/222 112+4 cam, 2800 TCI 10" anti-balloning converter.
Have all but maybe a couple pieces for the trans, some **** I used just to use. Probably unneeded but idk, lol list is as follows:
TCI Input drum (stock drum with Sonnax reinforcement kit),machined by Mason to make it a 4l78 drum, 8 Reybestos Stage 1 friction and 8 Steels. 050 dry, Sonnax apply plate, BW HE frictions everywhere else.
Sonnax HP Performance Pack, 2-3 shift valve, Forward and Reverse abuse valves, End plugs. Using Masons 3/4 springs, as well as the TG 7cs springs, Sonnax black wide band,
13 vane PWM case, 13 vane slide, 10 vane rotor, TG billet rings
"corvette" 2nd, Sonnax Billet 4th.
I tested VB and pump today. All - 17 or better except low/overrun valve @-15in.
Will be blocking the 3-2 control and downshift valves inboard, drilling 3rd feed to .135, BR to .101, will set band apply to .060. Blocking 4th acc. Leaving bore empty. Plugging PWM TCC feed hole per Sonnax instructions. Using Superior K0136 for 3rd accumulator check ball capsule.
Unless otherwise suggested I'll follow Sonnax instructions for rest of plate holes, which is. 093 for all but the. 052 AFL balance.
Believe I have to grind slots In corvette servo spring cover following TG 700R4 Jr shift kit.
So far that's what I've gathered. Any suggestions are very appreciated.
This truck is a daily driver, might see the track once or twice a year, definitely alot of passing, as I live in the country.
Will be tuned by me with HPT. Originally removed all TM but going back to 50%. Redline will be around 6200, or should be if I've built the engine correctly.
Thx in advance.

Anyone? Lol...Halp! If anyone has a better and easier to read spacer plate diagram that's labeled it would be appreciated too. Have the ATSG and Atra, and Sonnax, Presicion diagrams but some change checkball numbers, some are different names. Hard to learn with data that is different for the same parts.
