Honestly, the 6L90 may just be having the same intro years teething problems all the trans seem to have when they first come out. GM will get it dialed in over the next couple years after getting some warranty failures.
600 hp to the wheels is nothing to be ashamed of. It takes some minor mods to make a T-400 handle that reliably. Getting that bone stock is nice.
You will have a great truck when you get it done. |
Thanks for the offer but i think i stick with 6l90 cause it got 4l80 internals
600rwhp is alot of power for everyday truck i think if i pass the 400rwhp i be satisfied
