Pulled my trans yesterday and opened it up. 14,000 miles of easy driving. 2,000 of those miles were with a Quadzilla 80 hp programmer. The C3's were burnt on the inside diameter. 80 psi of pressure and 4 C3 clutches is not going to hold this Alli with a program. I replace the 4 C3 clutches with 6 Raybestos clutches and changed the pressure regulator spring. I also installed a Goerend converter.
The stock LML Alli idles at 80 psi and spikes the pressure to 220 psi on the upshift and down shift. ( not enough ) With my new custom spring ( different than early Alli ) it idles at 150 psi and spikes to 290 psi on upshift and down shift spikes to 240 psi which is exactly what I was looking for. Truck pulls alot harder and likes to spin the tires much easier than before. The Goerend converter couples like crazy. No other mods were done and no other clutches were replaced at this time.
