is there any way to to increase the line presure on a 5.2 ram 1500? I have been told that this is the reason for most of dodge transmission problems. I am also getting a fluxuation in rpm at highway speeds. You can hear and see the variation in rpm. At 70mph with the cruise set it will bounce about 300rpm. So if the rpm is steady at 3000 it will bounce up to 3300. Its almost like a mini slip. I was told it could be my lock up converter going bad. Any info would be great.
