EFI Connection, VERY IMPRESSED!
everytime i had a question, i would email them. It didnt matter if it was 2pm or 2am, i would receive a response back from them almost immediate.
even when my transmission was acting up, i thought it might have been something with the harness. i emailed them at about 1am and received a detailed response of how the electrical aspects of the transmission works, along with 2 wiring diagrams of the 4l60e input harness. they then told me if it is the harness, to send it back in for a total new one
turns out it wasnt even the harness
just wanted to say thanks to efi connection for the great customer service and quality products!
