sorry guys for the delay been very busy at work but i did tear it back down and pulled pump apart again am replacing the slide and o-ring but i wanted to ask what if when i tore the pump down the first time i used the alignment band but what about if the pump was misaligned in the holes
like if the two halves were set to one side of the holes and not center
going to get pinless sonnax accumalator pistons this week and thinking of repairing the original spacer plate with the hole repair kits just to be sure its not that
also going to replace the 3rd accumalator capsule in the case
jays ssz28 what should the 3/4 clutch pack measurement be book says 60-94
i have the pump back together and it seems alot better when you air test the circuits where before it felt like it was bleeding over to another circuit
at 75 psi holding the hole in the stator and supplying air to the port on the pump it shows a little leak between the cases and its torqued to 240inlb
you can just see a couple air bubbles but you can hardly hold the air pressure in the circuit holding the hole in the stator
I like to run the 3-4 clutch at no more than .030. I've run them as tight as .010
I wouldn't bother with the original separator plate, just go by the transgo instructions for the shift kit and their plate.
If the pump halves were off bad enough it would not go into the case before it gave any other problems.
Tranzman: Technically you are hijacking this thread, but I understand your problem is in the same ball park and you are mostly just watching this thread. So forgiven. However, if you want to start a new thread, I can move your post to a new thread.
So, I assume you have a scanner which confirms that the 2-3 shift is commanded, but the trans stays in 2nd gear. Very strange indeed; I also would have first replaced the shift solenoids and then the VB. I would expect the 3rd apply fluid to release the servo/band and thereby cause a free-wheeling condition. Perhaps an intermittent leak is so great that the serve/band do not release and the trans stays in 2nd gear. Sounds like higher line pressure causes the condition. Strange indeed.
Perhaps we should make this a new thread and you can then followup after you open the trans and hopefully find the problem.
And great having another experienced trans builder join this forum!
Sorry for the appearance of the hijack, I have no intention to hijack it. no need to move my post. I edited the content down because it is my current LS swap project and will be getting a newly rebuilt trans built for the set up. To answer the assumption, yes I have an OTC Genisys Touch wireless. i verified and even used full controll of the transmission with it and a friends Snap on Solus pro same problem, yes very strange indeed.
383Camaro! I had one like that and sold it to a friend, I made my own. I wanted to add the L/R oil and the P/R oil circuit. I also added 3rd release oil circuit. I drilled the holes at the factory locations in the separator plate. If you drill it on yours it requires 2 same PSI air sources to test. The second apply side, then the 3rd release side. 3rd release is a feed bleed set up like the reverse input drum.
hey guys got back to working on it and rebuilt the pump again put the new teflon slide and support in and put a new boost valve also pulled the ball and spring out of the pump and cleaned the ports didnt have anything in them
then put the 2 halves of the pump back together and clamped it with the pump band and lined up the holes the best i could and torqued to 240 inlb
then pulled the front drum and reverse drum and put the pump on them and turned it over and air tested it i can put 120 psi to the 3/4 port on the pump and before it used to bleed off right away now it has to bleed the air off before it releases the clutches
all the ports seem to air test alot better i am wondering if i torqued the pump enough the first time i am thinking i only torqued the pump bolts to 124 inlb
put it back together this time with the pinless pistons and new 3rd capsule and new boost vavle and pulled pump apart and installed the teflon slide
pressure tested before putting it in all shows good installed trans and still no 3rd or 4th
gave one last try with trans still in pulled and installed original valve body and also installed original spacer and we now have 3rd and 4th and lock up
i do want to thank all of you that were helping me and i am glad jays_ssz28 was pushing me to tear it back down cause i now know the quality is alot better

Did you see anything in the known bad VB that caused the no 3-4??? I would like to look at it and would pay for the freight here and back to you...
