How and when this product was developed...
In 1999, when we converted our shop car (a 1973 Dodge Challenger) from a small block 360cid engine to a low-deck 383 big block, we knew we needed a bullet-proof over-drive transmission that could handle high horsepower street cruising and 1/4 mile drag racing in a full weight, steel bodied car.
We decided to build a GM 4L80E because there were limited performance transmission options for 1000HP Mopar street cars back in the day and we wanted overdrive. The GM 4L80E was just starting to gain traction as a "high performance" transmission. Learning as we were going - especially because we were mating it to our Mopar - we successfully kept the transmission in one piece with minimal issues for over 10 years. We racked up thousands of miles of street cruising and track abuse. That started our love for the GM 4L80E.
As our customer base grew, the cars were getting faster and we were using more 4L80E's, we noticed issues with fluid starvation and lazy 1-2 shifts. It seemed more noticeable in the cars with 1.7 second and faster 60ft times.

Naturally, Scott's endless quest to know the "HOW & WHY" about all things mechanical brought him to proof out his theory. He questioned why he never had any fluid starvation issues or late/lazy shifts in his own car and determined that his "redneck" reverse filter assembly was the reason!
Since its inception 25 years ago, we polished up the original prototype design and ran it thru rigorous testing in several other high horsepowered cars.
We're excited to offer our Rear Feed Filter and Transmission Pan for the 4L80E to anyone that can benefit from it.
If you have any questions please call 401-270-8409 and we'd be happy to help.
