Soo the other day i hit bump little hard and sadly my dodge doesnt have best shocks, but same day my truck hit 260 so i shut it off and what not. Later i was working on figuring out what my overheating problem is so now i think i fixed it ,but as soon as i get her in 2 gear she sputters and my lights dim my check engine light comes on and stalls. It starts up everytime also ice rev it up in park/nuetral up to 3500 doesnt die also run her in strictly 1 gear up to 3500rpm and doesnt die on me but as soon as i either put it strictly in 2 gear or it shifts into second everything goes wrong. Also i thought what if i ran truck in reverse and went roughly same speed see if itll die it shows no sign of quitting. Please help
