Jakes makes a 'manual' version but it's just that, manual. The thing is, electronically controlled is one of the best things about the 4L80E, can adjust shift points, firmness, lockup gear/rpm/speed/TPS, can unlock on coast, it's incredible the control you get with one. It's a shame to remove that feature.

A simple on/off lockup was one of the big problems for the non-E transmissions, lurch, jerk, hunting, all that is gone in the E versions. And it's more expensive to do a 2004R or 700 than a 4L80E these days.

The adapters these days are excellent, and there's nothing wrong with using one. But, as you see on Jake's website, there is a JW SFI bell housing that can be fitted that gives you not only whatever bolt pattern you want, but is also SFI. Shoot, even Mopar guys are using them.

Cable-X boxes came down in price, see them now new for $280 on eBay:

It's becoming more common and more affordable to go to a 4L80E, and once you have one, you will plant your palm on your forehead thinking "I should have done this long ago'.

And you can recoup some initial costs by selling the trans you're replacing, as well as some of the other parts.
