Is it possible for the canned tunes in an evo to trash a transmission?
I got the incorrect gear ratio in gear 1 and 2 code and also the p1000 code which I don't think matters much. It won't shift into any other gear but 3rd and reverse after tearin around in snow drifts the other day nothin happened till the day after though which is weird.
I had torn around a little in snow before and never had issues but it was before I had the tuner.

That's why I was wondering if these programmers can possibly fry a transmission cause I don't tear around often and a truck isn't a truck unless you get it dirty now and then.
Oh yea the only thing I modified on the tuner was the tire size and advanced the timing since I ran lvl2 I never touched the shift firmness control.

Dropped the pan and found a glob of tiny shavings on the magnet and burnt smelling fluid and I know for a fact it wasn't burnt nor dark a week earlier.

I have an 04 newer body style F150
with the 5.4 and the 4r75e transmission, 33" tires and only 43,000miles on it.
I hear these transmissions are supposed to be indestructable. I ran it on lvl2 since lvl3 caused a loss in performance for my truck.
I noticed it shifted pretty hard but never thought much of it since the evo warrants the stock tunes. I dropped the pan and the fluid

Thanks in advance for the info
