Hello all, I am mostly a search and reader but needed some help on this one,. I have a 97 4.6 RR. My H tranny works in P. R. and 1 initially. Once I take off in 1 and shift manually up to dirve as speed progresses it does just fine after it hits 2nd gear of about 15mph+ and continues to work fine in drive until I have to stop of slow below 15mph. Apparently 1st gear isn't working? I have changed the fluid 2x recently and added Lucas and still the same issue. Not to mention today after trying it again, my purge ****** on top of the radiator broke off and spewed coolant across the drive. Is it as simple as gettin some sort of brass or metal replacement to insert or is this task more difficult. Thank you all for your advice and wisdom on this.
