Of First i did the sonnix repair flushed it and drove it for a few weeks and it started to do it again. I had the van apart for the brakes and struts so i dropped the pan and govenor and MADE sure the valves moved FREELY no binding and anything. Put it all together and its still the same from time to time.
I do have a spare fresh trans but i wanted to save it.
Someone told me to turn up the line pressure one or two turns and it should help will it ?
OR is it time just to say screw it
