95 s10 5sp trans question

Trans Problems. I have a 1995 Chevy S10 4.3 2wd. 5sp. The trans has gone out on me, When i first got the truck i towed it from NJ to Va and took the drive shaft off. well no one told me or i just didnt know that the trans fluid leaks when you do that so i drove it for about 4 months with out any trans fluid. I took it to a guy down the street who is good with trans and he took it apart and said it was toast so i was going to drive it into the ground. Well 3 years later it finaly goes out. he told me that it was a trans that was only one year the new venture trans and i was wondering if he was right and can you put any other trans in it?

Have your local salvage yard check there interchange book on what will or will not fit.
