Have had this 04 1500 HEMI for less than a month and noticed the trans gets somewhat confused during hard acceleration and shifts late and hard. When driving normally, it tends to upshift to soon to where it's really lagging. I have to really give it gas to get it to downshift. Checked the trans fluid level today and the dipstick came out a brownish red color (more brownish) color and the fluid smelled burnt. Is this the indication of a bad transmission or do I just need a good tranny flush? Help!!!
