Default th350

Ok guys I am pulling my 4l60-e out after it grenaded last week. This was a preformance built trans by monster transmissions and is my second from them in 2 years and only about 3000 miles total. I am going to get a quote from my new trans guy to rebuild the **** out of this thing but I also NEED a cheaper option due to the fact I am going to be buying another house in a month. What all is invlolved for me to swap over to a th350?
The car is a 97 z-28 with a 383 lt1 with LE2 heads and small cam made for torque. Car runs the 97 lt1 pcm and tune was done by trifecta. What needs to be done to convert if I need to.
