Looking at getting a Trailblazer Ext and can only find the 6 cylinder models. I was curious of how hard it would be to swap a 6.0L in it. I tried doing a search, but didn't get anywhere with it. I assume it would be as straight forward as swapping out the motor mounts and setting it in there. I wasn't sure what tranny they have in it and whether the 6.0 would bolt up to it. If anybody knows about this swap, I'd appreciate the input. Thanks. Tim

 

definitely a different tranny. you might find better luck on a tbss forum. good luck man, let us know.

 

Shouldn't be much different than any other lsx based swap into a vehicle. The transmission should even bolt up although I definitely wouldn't leave it stock.

 

If I were to settle for an I6 version, the swap would be a while down the road. Just checking on it ahead of time. If it isn't going to be as straight forward as my 4.3 to 6.0 silverado swap, then I would probably hunt for the 5.3 version a little longer. I was thinking it might be the same tranny as the 5.3 version with a different bellhousing, but that was just wishful thinking.

 

Don't forget that people swap in i-6 converters into their trucks all the time so it is at least a 4l60e variation.

 

I thought when people did the converter swap, it was out of the v8 models. That would be nice, if it is the same.

 

Nope I'm 100% positive people desire the i-6 converter.

 

agreed, the i6 converter help us v8 guys out

 

ok, I've never done it before, sounds good tho. Is the I6 Trailblazer tranny the 4l60e?

 

It's either a 4l60e or a 4l70e. I'm willing to bet it's a 4l60e. Either way I'm positive it's a 4l60e variation.
