Archived No shift, trans torn down 3 times, electrics replaced 3 times. this is long details

Is it possible the VB has a leak? Drainback had been getting worse in the last year but much worse now. Best as i remember the BD vb I have stated it did not fill in park back then like they do now. This is a 15 year old vb I installed 15 years ago. going to put gauges on it again.
Thanks

here's the final answer. Had to be air locked or pistons still too tight in the bore with the teflon seals and steel piston rings. Checked all the pressures today. All are 20# over specs except reverse which runs a steady 250 any speed or rpm and O.D. that runs a steady 100 psi. Tried to run off computer again. No go. Checked pressures on trans again. They be good. all are 20# over specs except O.D. which is 100# and reverse that runs a steady 250# nomatter what the speed. plugged in computer, still won't shift except 1-2-3
Works fine on mistery switches.
will replace that p.o.c. in dec. when I figure we have enough $ saved to buy one. Thanks for everyone's help. it is VERY VERY much appreciated.

You are saying that it goes into OD with the mystery switch, correct? When OD is engaged it is showing 100 psi and you have OD, correct?

Off hand, I'd have to say the PCM is the culprit now.

Yes, it works well with the super duper switches. I like the switches at the end of the armrest but will get a PCM when I can. I do not like my things cobbled together or something not working. upgraded is different. took a 7 miles driving before it started to shift right. I think it was working air out. all the sudden it was working fine. have 25 miles on it now and it is getting better. Another reason i think it was air locked is I had to put 1 more qt of oil in to get it on the full after the 23 mile run in trip.
Thanks for your help! d
