Do I need torque management? YES! TORQUE MANAGEMENT IS ABSOLUTELY NECESSARY FOR PROPER TRANSMISSION OPERATION. DISABLING TORQUE MANAGEMENT WILL CAUSE TRANMISSION DAMAGE AND/OR COMPLETE TRANSMISSION FAILURE.
TORQUE REDUCTION DURING RATIO CHANGE IS MANDATORY!
TORQUE REDUCTION MUST BE PROPORTIONAL TO TORQUE APPLIED!
Do I need a NEW torque converter with my NEW SHR transmission? YES! We always recommend a NEW torque converter with your NEW transmission. We have them for sale right HERE. At the VERY least, you will need to have your converter cut and cleaned by a professional torque converter builder. We can handle that for you if the need should arise. **NOTE** FAILURE TO EITHER REPLACE, OR CLEAN YOUR TORQUE CONVERTER CAN RESULT IN SERIOUS DAMAGE TO YOUR TRANSMISSION!
Do I need a custom transmission calibration? YES! FAILURE TO HAVE A PROPER CALIBRATION (aka TRANS TUNE) CAN CAUSE TRANSMISSION FAILURE.
Does my engine calibration affect my transmission operation? YES! Poor engine calibrations can DESTROY your transmission rather quickly!
Does SOUTHERN HOTROD LLC calibrate/tune transmissions? We do not. We focus on hardware. There are many qualified tuners available.
I have an 8HPxx 8 speed transmission equipped 2wd vehicle (Challenger, Charger, 300), should I install a single piece driveshaft? NO! We DO NOT recommend single piece driveshafts of ANY kind in 8HPxx 8 speed equipped vehicles. Vibrations and/or dynamic loads could cause CATASTROPHIC damage to your transmission. THIS CAN LEAD TO VEHICLE DAMAGE AND/OR PERSONAL INJURY. If you currently have one we recommend that you remove it.
