1999 4l60e compatibility question

[Get Bent]

I have a 1999 Tahoe with a 5.7l. My 4l60e transmission is trashed. I came across a 1999 Silverado nbs with a 4l60e that had a 5.3l. Will there be any issues (electrical, torque converter, mechanical, etc.) with putting the 4l60e from the Silverado in my Tahoe?

Thanks

You'd have to swap the pump, input drum/shaft and bell housing from your existing transmission to the 4L60E out of the 5.3L to get it to work. And if you're going to go through all that trouble, you should just rebuild your existing transmission.
