I am looking to upgrade or reinforce my Auto Transmission...
currently was slipping....I was change 2unit AT pass a year...
currently my setup is Power Enterprise Twin Turbo 330whp.

I saw some ebay selling heavy duty Alto red eagle AT clutch kits...
I have no idea is this workable or not with Twin Turbo...
