I have a 4L60E that needs replaced... badly, and with the demand put on this truck i figure it would be better to go with a heavier duty transmission ie the 4L80E so i just need to know, are they directly interchangeable? if you can help me then please do, thank you.
And another thought... honestly, what is the difference?i know the 4L80E is heavier duty but what real difference is there? is it the gearing? or just the basic overall construction?
