Okay so heres the deal. I just put in a new tranny with billet t/c, new trans cooler/ flushed lines/ and exhuast downpipe and intake. I took the truck for a drive today and after 45 miles no problems. It seemed to rev a little high before shifting but ever since I've had it the tranny was bad so I don't know what it shifts like normally. I got a new windshield put in and started the trek back home and the dreaded O/D light starts flashing. I am pulling my hair out. Thousands oF $$$$ on the truck and it never seems to go right. I have not pulled codes or had them pulled. What to do?????????
