Trailblazer isn't blazing. Perhaps a match and a quantity of gasoline would help.

 

what are the codes...it is a code for slip rate or gear ratio error? Sensors can't cause a pump failure. these aren't wheel speed sensors but trans input and output speed sensors

 

the trans uses 2 speed sensor to check convertor slip and gear ratio errors. the first is on the trans input shaft and the second on the trans output shaft. wss data is for the abs.

 

how have you confirmed the pump is bad?

 

Hey Whiskey, pleas humor Tech and answer his question!

 

-is the pump physically damaged?
-is the pump intact but develops no pressure...what is line pressure?
-how soon after install does the pump fail?
-what is the end play of the rebuilt transmission...it should be checked before teardown and after rebuilding.
-is there an associated vibration?
what does "replaced 5x under warranty" tell you diagnostically....go for #6

the bewilderment is due to the description...I really don't have time to fight you to pull this information out of you.

 

I'm looking for assistance from specifically educated/ experienced people familiar with this topic. Maybe other Trailblazer owners who have gone through the same thing, or transmission experts who have had the same issues with customer vehicles. People who have found solutions to this issue. I've put in a lot of time Google and found little in the way of solution. I'm not made of money and can't afford to simply take it elsewhere. The transmission shop is at a loss for words. I might have signed up at the TrailVoy forums but I'm not paying to be there for one issue. I'm aware there's a free option but it apparently offers limited and advertisement-riddled access. I'm not the only one who has had this issue.

 

Hey Tech, you tried, some guys just don't seem to know how to ask for free expert help. I am a bit disappointed as I thought you were more of a mind reader.

 

magic 8 ball says "outlook not so good"

 

That's probably the best expert advise and diagnosis that he has received to date!
Whiskey, if you simply play along, answer questions asked, supply needed info about your specific problem, you may be pleasantly surprised with the information you get here (for free no less). You have googled alot - I realize EVERYTHING you find on line is true, but you cannot google the brains of all the smart guys on this forum - but they can't help you if you choose not to supply them with the needed details.
Ok, I will end my little rant now. Just trying to help.
