Are there cost effective Allison 1000 Tranny upgrades
I have an 03 Dmax LB7, 4" Magnaflow exhaust, AFE Stage 2 air filter, coupled with a Banks big head wastegate Actuator. Now that I have so much power the Edge attitude warns me of impending slip and or slip. I have only ever let it slip 1% or so briefly.
My question is there a cost effective upgrade for the 2003 allison to allow it to take more torque by increasing tranny pressure without tearing apart the tranny and doing a full blown upgrade to a suncoast. I cannot effectively use the power in anything higher than level three.
slip is almost non existent in tow haul pulling a 30 foot 9000 Lb fifth wheel unless I am pulling steep hills and pushing it hard. the Big head is set for max boost of about 23 psi.
