Hi Weakminds, and welcome to the boards!
If you have a 1993 Chevy 1500 4X4 truck, you *probably* have the 4L60E transmission (a.k.a. the newer version of the TH700R4). The 4L60E is an all-one-piece cast aluminum housing (bell housing and main body are all one piece). The really important part here, is that the transmission is aluminum, and not steel, which means if the aluminum wasn't prepped REALLLLY well before welding, then it will be more susceptible to cracking than a steel case would be (for example).
Your transmission is well worth saving, as it is, in my opinion, the best automatic transmission ever made. However, if you plan on doing any serious off-roading, you will probably want to swap the housings or replace the entire transmission (will probably be about the same price).
Now, if the shop that did the welding prepped the material really well, and they are VERY good welders, AND you're not heavy on the throttle when in low-range, then you will probably be alright.
But (sorry, there's always a "but"), if your housing does indeed crack while you're wheeling - you're finished. It's not like breaking an axle or getting a flat tire where you can limp your rig home or fix it on the trail. When the housing cracks, oil goes everywhere (not good for the environment either), and you're completely finished, requiring your buddies to strap you home, take pictures of your rig being towed by a Ford, and dealing with life-long ridicule. :)
Anyhow, that's probably not what you wanted to here, but heading off-road, especially in 4-LO (where torque is multiplied a GREAT deal) - this quickly becomes a problem waiting to happen (even moreso with a freshly rebuilt motor that is producing a good deal of torque at the flywheel).
Hope that's helpful - Rick
