i love my 2012 challenger r/t but the crunchy 1st to 2nd shift is really starting to annoy me. ive done the cvd which from what i remember helped at the time. ive run royal purple syncromax and it it was any better i couldnt tell. i ran that for maybe 6k miles or so. 2 weeks ago i switched to redline d4 as ive heard it helped some people. i dont think it helped at all its just a different kinda crunchy now. i wanna drive a newer one to see if its any better. if they all suck like this as much as i hate to i may go automatic. i cant see the thing living a long life the way it shifts now. has anyone found the magic bullet? i really dont wanna get an auto.
