Hi RAEME, i hear what your saying , i seem to have the same problem , ive replaced the gasket tightened bolts put sealant on the gasket , the ute sits for sometimes months , sick of having to top up trans fluid. This time ive put in a deep sump pan and and new gasket sealant filter and gone over everything, bolts the way i did it gone over the tension of the bolts for bout the 50 th time now ill just cross my fingers and see . Think its just good luck if they dont leak.
