Howdy!, I’m Truckdoug, aka “the 4L80e guy”
I build 4L80e’s and Turbo 400’s for high performance vehicles. I offer custom and stock options for a range of budgets and applications. Not sure what you need? I’m happy to discuss your situation and offer my recommendation.
As high-quality component prices continue to rise, I must raise the price on complete units Jan 1st 2025
