I feel knowing what I know now and previous experience cars above a certain power limit having the oem od trans would need cons attention and I feel like it would run different almost every pass the availability of a shop parts and time would be overwhelming I would think…. Aftermarket trans i feel like actually slows it down a tad but it’s sooo frowned upon I don’t get it… OPINIONS 👂
Aftermarket trans allows for most peoples power goals. An OEM one will not last and cause issues further down the line.
Ultimately: Less shifts = faster times.
