What trans can fit a 2008 4.3?

[Fredboy2287]

I have a 2008 Chevy Silverado 2wd 4.3 Auto. My trans is going out and I was wondering what transmissions would fit it, could I use one from a older truck or from the same year. Just wondering what transmissions would fit it.

You are limited on what you can do because you must have the correct year range to pick from.

 

Your transmission should have a purple connector with a 15pin harness and that started in late 2005 and in all 2006's. Then in 2009 they switched to a 19 pin harness.

 

I would just remove yours and get it rebuilt unless you can track down with ease the year range you need.
