Thanks for visiting CAConversions, with 20 plus years of research, trial & error & patience we CAN make all Allison 3rd and 4th Generation 1000/2000 transmissions work properly behind almost any engine.
Using only Allison Medium Duty programming, which locks your torque converter at 2nd gear, the converter no longer slips, which reduces heat significantly. Heat is the number 1 killer of transmissions! Only Allison programming will keep your torque converter in lock up at 2nd through 5th or 6th gear while both up shifting and down shifting.
Allison automatic transmissions have adaptive learn capability, proper parameters in the programming along with correct set up of TPS are essential for developing smooth and consistent shifting. All of our 6 speed programs have tap shift capability.
The more we learn about these transmissions the more nuances we have discovered, thus making CAC’s solutions ever better.
