I lost power to fuse #20 in the cabin fuse block. Can anyone share on where I can find a wiring diagram for that fuse and where it draws it's power from. I have power to the ECU/PCM and to and from the ignition switch.

Driving on fwy after a traffic slow down, truck would not go faster than 25 mpg. RPM's would go high but no speed. Replaced trany filter and gasket, 1-2, 3-4 & 3-2 solenoids, trany valve position pressure switch, torque converter modulation valve and throttle position sensor. Replace TCM w/rebuild. No codes on dash. No luck issue persists. If press hard on gas pedal it feels like if it goes into a gear but then revs up and goes back to second.

I'm guessing the latest chase is my positive battery cable gets corroded or something else? I keep spreading money, but now I'm trying to to search around, any one remember the older Chevy's?

Why does my 04 suburban lose power after hitting a bump or power hole at 35 mph.

My suv have lost power, and trembles a bit when pressing the gas. It has been doin this since the service air bag light has came on, about a week ago. I have no clue where to start with this. Has anyone ever had to deal with this?
