Its the same transmission but with a HD case. Keep the Heavy Duty case and rebuild it. Rock Crawkers seek these Heavy Duty cases out.

I'm probably gonna pick up a 700r4 from those guys. Definitely reasonable and a few stages of options.

thanks for the info, just a few more questions. im new to rebuilds and i took apart my tranny so it doesnt look too hard todo, just worndering if overdrive is an option i should be looking at and if im going to need any special tools for the rebuild? im assuming the spindles or w.e their called im going to reuse, but the rest of the internals will be new from the kit right?

For the Blazer you do not need the Over drive unless you plan on changing out your axles 3.08 gear ratios to something like 4.10, 4.33 or 4.56 ratios. The Blazer is fine with a standard 3 speed auto. No need for Over Drive.
