do you have custom tunes on your sct because if so that shouldn't have smoked the tranny.

yeah i do, i got a heavy foot, but i dunno maybe it was a combination of both. a little before it happened i noticed that it had a weird shift going down the highway, then about 45 minutes later it was done. i had been getting on it, then one the way through town it kept shifting weird and wouldnt let me get out of 3rd gear.

if i owned your truck with your setup, i would get 5.13 gears with those big ol bolognas. it would take alot of stress off the tranny especially with your heavy foot lol. sct's are not suppose to kill your tranny. who did the custom tunes on it?
sorry im a slow typer lol.

i got 4.56, which runs good because at 1900 rpms im doing almost 70, and it runs just fine going down the highway like that, i run over the speed limit a little so it works out good

im telling you, it needs to be bigger to be close to stock. just look at this chart and it will say you need at least 4.88 or 5.13's
Chart Gear Ratio
