Replaced Trans Now No Oil Gauge Wont Read. I start up and it stays at 0, i have a check engine light on but when i scan for codes nothing comes up. Its a 2000 Jimmy 4x4auto. does anyone have ideas on what to check? Thanks

 

Mike - oil sending unit is on rear of engine below the dist. make sure wires to it didn't get knocked off or even pinched between block and bell housing when doing transmission

 

thanks im gonna take a look at that tomorrow, i guess worst case i'll rewire the gauge or just run a new one
