So here's the problem while going around 60 to 65 mph on hwy 50 I was going also ng when out of nowhere my 2005 ram 2500 turbo diesel Cummings 5.9 l v6 truck just stopped being able to move forward. It's like it just went into nuetral. No check engine light came on and I didn't have any warning there was something wrong. Once I got my truck towed home it has sat ever since. It starts just fine but will not go into any gear. I've checked the selector rod going into the transmission and it is moving as it should but the truth will not catch any gears. Any ideas fellas?
