hey guys, haven't been here in a while. i posted this up on ls1tech and didn't get too many replies. maybe yall can give me some idea's. thanks guys...

i spent almost all day putting my new torque converter in. i added fluid to compensate from the fluid lost from the stock converter. also removed the checkball if that helps. still had it on the lift. started the truck, everything sounded good, put it in drive, reverse and was working fine. drove out the hobby shop and it was fine. got on the road and gave about 1/2 trottle. the converter was doing it's job, flashing like it should. slowed down and put it in first. poked it 1/2 to 3/4 trottle and rpms jumped quickly to 4 to 5k, shifted to second and nothing. the motor was sitting there reving like it was in neutral. pulled in the parking lot and tried every gear and nothing, the truck wouldn't even budge. checked the fluid and was good. i thought maybe it could have been the fluid to low or to high. please give me some ideas on where to start... thanks fellas.
