Transmission help

[Kristi Huffman]

I have a question.. Can you put the translation from a 2000 chevy blazer 4/4 4.3 v6 into a 2003 chevy avalanche 5.3 4x4 4L60E

My daughter's truck has transportation troubles... I'm trying to figure out if we can just use the tranny from the 2000 Blazer it's a v6 4.3..... The problem is that it needs the 3-4 clutch and Piston but I've been calling around and it's expensive to get a tranny rebuilt.... And we have this blazer and it has a good tranny in it.. So will it work.......

Welcome to this forum!  Your translation/transportation/transmission question is understandable but I'm not sure why you're asking.  Taking an old, major component from a donor vehicle and transplanting it into a different year and model of vehicle will only be cost effective if you do it yourself and you know what you're doing.  Get some estimates to fix the Avalanche from places that specialize in transmission repairs.  Leaving it to the professionals will save you a lot of headaches and money in the long term.
