Trans swap

Anybody know if a turbo 350 transmission will fit an 04 silverado 5.3 LM7? Just got a deal on one

It will bolt up to the engine, as long as it's a Chevy version and not a BOP trans, but why?

Just wanted to know if it will fit my truck. Dude I know is selling it for $50 but I wasn't going to buy it if it didn't fit. You know how the 4l60s are, can't hurt to have a backup

Will not bolt right up lol.  The bolt pattern for the bell housing will bolt up.  Everything else wont.  The distances probably wont be the same.  You'll need a different flex plate.  Not to mention you wouldn't be able to run the trans without some kind of controller because your 4L60 is electronically controlled and the TH350 is not. Different driveshafts as well because its a different length.  Dont waste your time and money.  Spend a bit more on a used 4L60e or just rebuild yours when it goes.  TH350's are good transmissions but they dont have overdrive.  It would probably hold up to the 5.3 for a while but youd be happier with a 4L60e.
