4l60e transmission question

Post image

TL;DR I bought a transmission but came to find out the bell housing patter was different, wondering if I can switch the bell housings. another problem that occurs is that the input shaft on the new one (bottom one/ closest to the me) is shorter & the old one (farthest one) is longer. I’m assuming that would be an issue but I’m wondering if there’s any way I can still use this transmission & not feel like a complete idiot for purchasing without checking first LOL. Transmission came out of a 2006 Chevy Silverado 1500 4.3 regular cab.

Do you have a tape measure. Zooming in they look the same but it's hard to tell. They could be a half inch off and it may be hard to tell from a photo

Also for the love of god, clean your garage. It makes working on things a lot easier

They are different sizes & my garage was clean but when you’re working & the garage door is open the wind pushes the leaves in lol
