I am switching the Muncie 4 speed in my car for an automatic. I want a 4L60e for it. How many of the transmissions would interchange with the original from a '98 Camaro? Hopefully something a bit newer that are plantiful to find will work. I bought an automatic wiring harness the first time and will have my PCM reprogrammed for the automatic. No 800+ horsepower or anything just a cruiser. Thanks for the help.
