4l60e question I couldn't figure out where to ask this, so I'm going to post this here. Can the LT1 4l60e and the LS1 4l60e be built to perform to the same level? Im only going to push 400whp. And I plan to go with the PB Level 2 4l60e. But I have the LT based 4l60e. But other than the removable housing. Is there any other reason to go with the LS based Version? Because they are all the same price and have the same HP rating. I won't be tracking or launching the car with slicks. I am mostly confused Bc there is a guy in my car group that always says he has a built LS 4l60e not the LT 4l60e in his Caprice as if they can't be built to perform the same.

Moving it over here where you'll get some discussion.
It's mostly a matter what's involved in your build. The later LS trannies had fixes and upgrades not found on earlier ones. And of course they are not interchangeable - an LS motor requires an LS tranny and vice versa.

The input shaft on a LS 4L60E is different than the LT, but other than that they are basically the same other then a few upgrades. The LT trans can be built to handle the same power as a LS trans.
They can be built to the same capabilities the units are virtually identical from a build perspective,

Thanks so much to everyone, I figured he was just blowing smoke. I will be buying a trans from you guys very soon! I only plan on having 400whp in the 4200lb land yacht. So the level 2 should be sufficient for a street car that will never do more than a stop light pull.
