So I just had my shop install a built tranny and vigilante converter and the car feels like the converter never locks up. I pulled the codes and this is what I got

Very common codes for a stall converter--- Good news is that all the codes are "false codes" and just a result of a stall --To get rid of them all you must get a re-tune--and not from any handheld as none address enough tables to correct the codes----False misfires must be addressed -- and the PWM of the converter lock-up--as well as all the slipping tests and codes--

So do you think once the car is tuned the codes will go away and the converter will stop slipping? Also I had a converter in my other tranny and never had this issue

Well that depends-----If the slipping is caused to false triggers from the stall--yes they will go away---however if you have a mechanical failure issue then that will need to be fixed---All I can say is that stalls create false codes which can result in problems---
A stall converter creates extremely high trans temps--So the trans/converter can very quickly fail if ran too hot too long---It is a MUST to install an additional aftermarket trans cooler with a stall to bring temps down--The magic number is 200* ---You don't ever want to have it run at say 220* for more than 15-20 mins or so--
Also these cars have a trans cooler built into the radiator---so a lower radiator thermo and lowering the fan settings will also help cool your tranny---I always use a 160* thermo and lower the fan settings---
