Good morning everyone. I've been having trouble with grinding of the gears going into second and third. It's much worse if I'm revving up the rpm's accelerating fast. If I take my time shifting and accelerating easy, it's not too bad. I have a 2002 Wrangler with the 4.0L and 5 speed NV 3550 trans. I've even changed the fluid inside and switched to the Royal Purple Synchromaxx fluid. The clutch seems to work fine for all the other gears including reverse. Any ideas? Rebuild or Replace. Would definitely change out the clutch also. Any brands also to recommend? It's pretty much my daily driver with occasional off road use.
