Well heres another trailblazer trouble I've got to deal with. I was on way to work and to take my kids to school when without warning no sounds (whining, grinding, etc ) it was like I was in neutral all of a sudden. I had to pull over in someones yard to get off the road. After the kind gent pulled me home I noticed that when I shifted gears the indicator was showing I was shifting. No power at all to the wheels. I shut it off let it cool down and when I pulled dipstick it had fluid all the way up the stick. I then let it run for near a half an hour and checked again same result. Fluid looked good no burnt smell, no metal debris or any debris for that matter. Fluid looked clean as well. I'm guessing pump failure from my research, but with labor to pull and replace transmission around 450-650 and the cheapest decent used I could find for $550 Im hoping replacing pump may be a little cheaper. Also a nearby shop offered to tow it there and rebuild the one I had for $1250 I have that option as well. After having to install main interior wiring harness among a host of other electrical and hvac problems, (still need to replace the plenum or whatever the hell its called) I'm about done with this thing. I'm looking to trade to a 87 Monte Carlo Ls with a rebuilt 4 barrel 350 and transmission excellent stock interior and 22" wheels but now this. What's the best option or how close am I with the idea of a bad pump, any and all suggestions greatly appreciated. Thanks.
