I did my trans fluid change almost 2 weeks ago. I've had problems with engage into 2nd gear for some time now, but when I refilled the trans with Royal Purple trans fluid, getting into 2nd seems a little difficult, specially in the morning. Can it be that it needs more fluid, even though I filled it up to the fill hole? OR can it be that the Royal Purple is less thick that the ATF that it originally had? or maybe the shift fork is getting messed up on the trans. Any Clues?
