Hello. I have been looking around the forum but can't find anything quite like what's going on with my truck, so I decided to post. My truck is a 1999 dodge ram 2500 Cummins 2wd and it is having transmission problems. When it's cold, it won't lock into gear very well, so I have to give it a little bit of rpm and then it will slam into gear. Also, when I'm braking to a stop, sometimes it will stay locked in gear even when I'm stopped and it will lunge forward and sometimes even die. I've hear things about cleaning the grounds but that didn't help any. Any advice would be appreciated. Thank you!
