Customer Question
I have a 2002...

I have a 2002 Chevy Avalanche 1500 z71 4x4 4dr truck....i got it 3months ago.....few days after I got it the transmission started leaking ...

Mechanic's Assistant: How old are the hoses? And what driving conditions do you most often encounter?

All the guy who I got it from said was he has had it 5yrs an never had any problems with it.....

Mechanic's Assistant: Are you fixing your Avalanche 1500 yourself? What have you tried so far?

Wait a minute....

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I was driving it till the transmission just stop working driving down the road....i step on the gas pedal an it sounded like gears bouncing around in something

Automatic

Have you been under the truck to see for sure where the leak is coming from? Will the truck move if it is in 4wd?

Customer reply replied 7 months ago
Well.....i can't tell...its leaking to the cross member....an it is in 2wd...when I got under the truck I found out that the driveshaft to the front tires is gone
Chevy Mechanic: kalamykid, Shop Owner/ Tech replied 7 months ago

Was it ever there? Look at the transfer case and see if you can see any cracks in the case.

It will not move..when I give it gas it sounded like gears bouncing around in something
Chevy Mechanic: kalamykid, Shop Owner/ Tech replied 7 months ago

With the engine running and you put the trans in drive, if you put it back into park do you hear a clanking nose that is repetitive?

Customer reply replied 7 months ago
I called the dude I got it from.....he said he didn't know...he never put it in 4wd
Customer reply replied 7 months ago
No.....it only makes sounds in gear
Chevy Mechanic: kalamykid, Shop Owner/ Tech replied 7 months ago

Did you go out to the truck and check it for cracks in the transfer case?

Ask Your Own Chevy Question
Customer reply replied 7 months ago
Don't c any cracks on it.....an a friend of mine that works on cars said that the only way it could be the transfer case was if it was in 4wd
Chevy Mechanic: kalamykid, Shop Owner/ Tech replied 7 months ago

That is not true. Go out to the truck and start the engine, pull the transmission dip stick out and wipe it clean, then restick the transmission and see if the fluid level is low please.
