Well fatherhoods absolutely kicking my ass along, with work and maintaining the property…
BUT…
I got a good chunk of the valvebody started, along with the sonnax performance kit. Took me awhile to get a grip on things I had laid out 4 months ago.. but I got there. Washed the valvebody with acetone and started assembly the pieces. I washed them as they went in with a synth brush and acetone. It appears I took out quite a lot of valves that don’t seem to get mentioned much online, so I’m sure glad I have this thread to confirm orientation and position.
I have one valve left to put in which is the TCC valve and spring from the sonnax part. I need to verify if the bore is worn out or not, if so there’s a sonnax kit with a reamer and oversized valve.. I think this one should be alright though.
Although the 1-2 and 3-4 shift solenoids are cheap enough , but it’s so easy for the money to add up… I decided to test them and re install. First test I found, had me activate the solenoids with a 9v battery and listen for the distinct open and closing noise, and that checked out. Next was to ohm them out. It seems gm says 20-30 ohms but some people seem to say 20-25 is preferred. One of mine read 20 .3 I think and the other 19.9. I figured I’d try and re use them. As for the pressure switch that tells the pcm what gear is selected, the kit came with new gasket rings for them but there seems to be a plastic film and some debris under. I’m going to see if I can just flush it out in the parts washer or something.
The black valve and new spring are the upgraded sonnax parts compared to the OE on top.
The kit comes with a rounded shim which is placed in the bore to take up space against the wall of the valvebody and against the spring and valve. I used a feeler gauge to push the spring back.
The kit came with all new metal pinless accumulators, and some plastic check balls, and 2 steel balls to insert into one of the pin bores that isn’t a blind hole. It states to pean a stake in the bore after inserting them.
I drilled out the separator plate to .093 and 0.52 in the holes specified and gave it a once over with a fine 3M nylok brush type thingy. The sonnax kit wants me to peen in the PMW hole in the separator plate, with a supplied aluminum plug and 1/16 hole drilled prior. Also there are a few spots where the checkball obviously sits, that overtime depress and form a little ridge on the opposing side of the plate, gently tapped it with a body hammer to smoothen it out.
I left the PWM/EC3 modification to last because i wanted to be sure that id want too, before i close up the hole in the plate. It seems to be for partial slip in the torque converter from factory which many higher perfomance and aftermarket ones only have on/off. It states unless you know you have partial slip material in the torque converter this modification is recommended.
After going through i dont know how many garbage bags, using one everytime i wrapped these parts, i decided to just buy a roll of film for wrapping parts better and without so much waste.
