I've been wrong before but I think that in this instance,if you fit a new set of leads and plugs and see if you can borrow a coil pack to check your coils and DFI(before actually buying them)there's more than a small chance that your tranny will come back to life There are heaps of threads on this that you can check out.At the end of the day you won't have 'wasted' a cent.Good luck
