box is zf24hpeh, but lets assume its a gm box (same princilpes)..when i load the gearbox at say 15mph to drop it out of 2nd into 1st (ie boot it) it slips like mad..ie no go..
now i have been trying to sort by altering line pressures and shift compltion delay etc...but not much success..
now i know i am lacking in autobox knowledge, and have hense been googling galore, but no results of interest.
so got any thoughts as what i need to adjust..no msq included as its related to box i dont think anyone here is using,principles i am after..
thank you simon
ps other than that is perfect..
