how's it goin I have a 03 Dakota has p0943 low pressure code replaced all sensor it hard shifts only if I turn the truck on agian after warm only in 2-3 could this be leaking trans cooler lines thanks

 

Good lord learn how to use punctuation.

 

Go under your rig and check the two cooler lines from the trans all the way to the radiator. If you had a leak you would know it though? Shift your dak into N while running and check your trans fluid. If its low that could be your problem. I dont know much about the 545rfe?? but if its anything like the 46RE the cooler lines should go from the drivers side of the trans to the radiator or aux cooler.
