I'm still trying to get my truck to shift smoother. I changed the oil in the tranny and used the stock mopar stuff. Well it still kinda has the two step catch feel when shifting between gears. I'm wondering if the syncro's are shot in it. Is there anything I can run in there, that could smooth out the shifts? I really can't stand this. Damn 2000 truck, I've had 60 year old tractor's shift better than this. Please help.
