    Higher stall tq converter from na grand prix in sc grand prix

    Just wondering what changes need to be applied to make this higher stall tq converter work in my sc car. What tables need to be changed. Or can i just simply copy the tq converter tables from the na grand prix and put them in my tune?.

    The stall speed isn't much more than the GTP, isn't it like 2000 to like 2400-2500 for GT's.

    Not much really has to be done and it might drive and shift just fine.

    But I've read this in the past just never dealt with it. Some get hunting issues with the 3000 stall converter but that's bigger than what you are using.

    Just adjust the TCC table! Best thing to do is to graph your shift table and the tcc tables all together. Then you can see the overlap tha needs changed
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
