lbheart,
thinking it over... take a look a tables D3802 and D3803 (type one of these in the search box and click the search button)...
if you decrease these tables then line pressure will go up.
i see what you mean.
how much should i decrease them by?
i'm wondering if i should decrease entire table or just the low pressure side of things i dont want to send the pressure too high and do damage
what are your thoughts?

The low pressure side of the table is the high current portion... try 10-15% decrease.
Do you have a pressure gauge to connect to the line tap on the side of the case...? If so you can watch line pressure after you change the table.
i have several pressure gauges ill have a look and if not ill buy a suitable one.
what sort of pressures am i looking for?
where is this tap?
picked up new full recon box yesterday its in my shed ready to go for the weekend
where are you from joecar?
The stock Holden values for these tables is very very low in the left top corner, to the point my built 60 wouldn't select 1st gear at idle....
Another "cause" of the 3/4 failure is if you leave the shifter in D and the car kicks down to 2nd under any sort of load the 3/4 pack is still partially engaged/ slow to exhaust when it selects 2nd and the 3/4 pack loses... :( (ask how I know this)
Doesn't happen if the shifter is in 3rd at the time of kickdown to 2nd.
