Well if I'm looking at the pics correctly I'm saying you're spending plenty of money on your hummer. That's the Peto-Bismol or Mixcool. New rad, rebuild transmission and flush the cooling system and replacing any oil saturated hoses. I recommend getting a good look at the rest of the vehicle to get an overall condition of the hummer. Curious. Why do you have your cam phaser solenoid out?

 

 

That depends on where you live. If you live near the golden triangle of Ontario, I would say it's fair. Not over charging and not cheap.

 

It cost me around that much when I had it done.

 

Update: found a shop with tons of transmissions and have a lot in stock. They have my transmission in stock which is a rebuilt. Asking 1750 plus tax with labour.

 

Make sure it is for an H3.
Specific valve body and trans pan to clear the front prop shaft.
