How do I strengthen my transmission it's a 2002 automatic? If I have a 120 wet shot, all the bolt ons, upgraded fuel injectors and fuel pump Apexi tuner... Was dynoed at 427 HP... This is the fourth tranny!!!!

 

Were you using stock transmissions?

 

Using a premium trans fluid like amsoil or redline, they cool more rapidly due the their ester stocks. using an aftermarket trans cooler may help aswell. heat kills a/t trans and if you can manage the heat you can prolong your next trans. paired with the shift kit available for the auto you should be set.
