I had good luck with taking out 1/2qt of oil and replace it with transmission
fluid.I would run it for 4 or 5 days then change oil.That will clean the top real good. good luck deweyii

My best guess is it is going to be either the crank positioning sensor, or camshaft positioning sensor. Hope this helps.

i have an 04 gmc sierra. 4.3l 4x4. 5 speed manual trans. i have a cpl problems i cant figure out. first i am having what i think is water proofing issues with the distributor. it will start misfiring and lose all power. i replaced the entire distributor. i also replaced plugs wires and cap and rotor button. still does it. is this a common problem? can anyone offer suggestions please? also when i am accelerating it seems like the trans rattles and the speed odometer fluctuates. after the rattling continues for a bit the abs light comes on. i have replaced the front wheel bearing as they were starting to go bad. the trans has always rattled kinda bad but the light never came on until i replace the wheel bearings. im sure i put them in correctly. not sure what the issue is please help. thanks.
