I have a 94 dodge ram 2500, with auto trans, 5.9l cummins. While driving I noticed my oil gage at 110(maxed out on gage). I also noticed that when I let off the accelerator even a little it would go down to normal. It goes up and down as the truck shifts, how far up depends on how far I push the accelerator. If I put the truck in reverse and back upit stays at normal. If I put the truck in neutral, or park and rev the engine it stays normal.

I also notice that it is actually shifting better than it has. Anyone have ideas?

Thanks
Dave

 

dont know dodge but you might have to hook up a different guadge and check it. 110 is kinda high. my jeep will get to 90 on the guadge cold driving . when it is hot its normal.

 

I found a ground wire off, reconnected it and the oil pressure problem seems to have been solved. I'll run the trucka few days and let ya know if it works.

 

truck is still running ok after I connected theloose ground
