    1998 z28 tranny problems

    bare with me. I did the best job I could at getting the most data the only way I new how. my buddy and me put a factory torque converter in...all was fine for a few days except the shifting at WOT witch wasn't a big deal. well he calls me the other day and says he lost 3rd. now when I drive it feels like its all gears. It feels like its not holding pressure inside the transmission. I have no idea how to go about fixing this without yalls help. I have a log with all the transmission parameters that it would let me load. if someone could take a look and let me know whats going on.

    Anyone? If i loaded the wrong log i will load whatever someone needs. We put a new converter in it and all was fine for a few days. Then all of a sudden slipping in every gear except 1st. Like when a 5 speed clutch slips. This is a auto however. I beliebe something is losing pressure. Do i need to start with putting a pressure gauge on the 4l60e?
