2004 Isuzu Axiom willnot shift into 3rd gear...goes back and forward with no problem...when i turn the wheel, itt resists a little and the back two wheels kinda slip...when the truck is in 2WD, the indicator lights on the dash flash...when in 4WD, they dont flash. I live in MS and there seems to be no one who works on Isuzu's anymore. What could this be?
