Heater hoses?

I blew a hose on my 100K 2005 TB the other day. I took it to the dealer, they sold me a cople hoses and a water pump and T stat. They also told me there are two hoses that should be replaced "Behind the transmission" and it would be $1200 to remove the trans too replace them.
Does this sound right? Or are they trying to squeeze more money out of me?

Thanks
Anthony

They are trying to squeeze money outta you. Anytime any mechanic or dealer tells you something needs done it prolly won't other than what your there for, so always check it out your self first. I say that if it's not in your OM (owners manual) on the list of things to service then don't service it. Unless it's a common replace item you know for sure may need replacing. $1200 yeah right i'd tell em to shove it up there A**. Sorry that's just ridiculous to remove the trans to service something that may not need to be!

Which hose did you have to replace? Heater hose, radiator hose?

What hes describing up above "The line that goes behind the engine around the transmission" is the heater hose that goes from the drivers side of the block, to the heater core.

How do I know this?

Mines bad too.

The only (practical) way I can see to replace it w/out causing myself too much grief is to mickey mousy geri-rig a 4' long piece of 5/8" or so heater hose around the back of the block and totally BYPASS the OEM heater hose that is attached to the block with two little bolts, leaving the bad and leaky OEM heater hose still attached but bypassing it completely.

For my 2002, GM has discontinued the stock heater hoses and Ive been told to use heater hose as a replacement anyways.

Fortunately, my heater hose hasnt blown yet but is seepy and leaky.
Im running on borrowed time!

So this is somewhat legit? There are hoses that cant be gotten to without huge amounts of labor. Wow, that makes me feel better. I still think $1200 is a little high. I will try to do it myself.

Thanks

Hey, I do all my work myself and have tackled some pretty big PITA jobs on my 'Voy...but after trying to trace down the heater hose, the only way I could think up that would be somewhat easy would be to disconnect the heater hose that wraps around the block and bypass it with heater hose, leaving the original heater hose connected to the back of the block about the transmisson still.

So yeah, it is legit. The price is wayyyyy out of line, IMO
