Does anybody know offhand what year they started putting the 700r4 into Blazers? I need to get a set of the struts that go from the cast transmission shield to the engine mounts and the plate that goes under the engine mounts that the struts attach to.
 
I needed the two braces and the two brackets that go under the engine mount. I go down to the local Chevy dealership and wouldn't you know it, they don't have either. They were pretty good though. They got online and accessed something called "OEConnection" or similar. I guess all the Chevy dealerships subscribe to it. They all have access to each others inventory all across the U.S. He types in the part numbers and then prints out who has them. As a result, I am getting the braces from Franklin Chevrolet in Russell Springs, Kentucky, the left hand bracket from Oakland, California, and the right hand bracket from Levelland, Texas. A PITA but at least they are all on the way.

Yeah, but I don't know their names. They have always been pretty helpfull, even though they never have what I want.
 
They are braces that go from the engine mounts to the cast aluminum bottom torque converter cover on a 700r4 transmission.
 
You will get varying opinions here on that. Other folks are no doubt in the same boat and if they haven't had problems, they will probably tell you not to sweat it. My personal opinion is, they put them there for a reason. I also had the side bracket on my NP205 that is now no longer possible since I did a doubler. So, I want all the added support I can for all that weight back there.
 
I just swapped transmissions and the new one doesn't have the holes to mount the cover so I can't use the braces. I have been wondering if this is going to be a problem?
 
If you have a 700r4, then you should be able to put the cast cover back on. Unless you put in a 2WD 700r4 perhaps?
 
As said, you can buy a cast aluminum cover from a dealership, which is what I did. The question is, does a 2wd case have the same configuration as the 4wd case allowing it to bolt up? Of that I'm not sure. If it does, then you buy the cover, braces, and brackets. I will post pics of when I install mine in the other thread I have going about my Doug's headers install.

The 4wd models came with these strut rods one for each engine mount and they attach to the bell housing cover. As for the 2wd models, they were not needed and there for did not come with the extra support and would have the tin bellhouse cover instead, which used sheet metal screws to attach instead of bolts like the 4wd aluminum cover. The 4wd models had alot of different things then the 2wd models like the strut rods, transfer case strut rod, different engine mounts and so on. I recommend you put them on if you do wheeling.
 
The question is, are the holes for mounting the sheet metal on the 2wd model tranny body the same as the holes on the 4wd model that you can mount a cast cover on? I can't imagine them making an entirely different tranny body, but then again..... If I recall correctly, and I might be wrong, it seemed like on mine there were two holes available on the outer edge. One took a screw, the other for the cast cover used a small bolt.
 
I've seen only two 2wd 700r4 and they both had the tin cover as for the bolts I really dont remember but I just looked at my 700r4 in the garage and didnt see any other holes for a different config. So this ones up in the air unless someone could enlighten me on the matter.
 
The only other difference I have found here is that the torque converter cover (dust cover) for the 4WD version was made of cast aluminum instead of stamped steel or molded plastic, and it used much larger bolts to attach to the transmission, as it also made provisions to attach strut rod reinforcements from a bracket that mounted under the motor mounts to the lower portion of the cast aluminum dust cover.
