Transmissions

Today's modern turbo diesel's churn out a lot of torque. As OEM manufacturer's are trying to accommodate this power with larger cooling systems, bigger torque converters and better clutches, the aftermarket has created even more powerful tuning devices, larger turbos and bigger injectors that absolutely overpower the stock transmissions. At Alligator Performance, we understand this and that is why we sell the best parts to fix weak factory components. We carry the top Diesel Performance brands such as ATS, Suncoast Converters, Southbend Clutch, Valair, BD Diesel, Mag Hytec and Firepunk Diesel. If you aren't finding what you need, email us at sales@alligatorperformance.com and we would be happy to assist you.
