Transmission Cooler Line fix 1972 C10
 

So I went to a mechanic down the street from me, and the transmission cooler line is leaking, and as well as the drive shaft carrier bearing is extremely worn out and I need a new one. With labor and parts and tax, is $350 a reasonable amount? Or is that way too much? I'm in Arizona by the way.

also a 2nd question, how hard would it be for me to fix the transmission cooler line myself? or is that something that you need to have special experience for?

In my experience...and lack of it.....I find that how "hard" something is to do
(including mechanical and every other task) is less dependent upon the job to
be done than the person doing it.

Give it a shot. It's not hard. Once you figure out where it's leaking.

The trans lines should be an easy fix. You can replace them for not much money.
The carrier bearing it a bit more involved but nothing you could not do with help from the board here or a friend that has done it before... If you are going to take apart the drive shaft I would replace the u joints at the same time, and maybe have the shaft balanced. I did not have mine balanced and it turned out fine, just mark it and put it back together the same way... Also get u joints like the originals with the grease fitting in the body and not in one of the cups...
I would think you could do the job yourself for under $200 and that would include all the parts and some of the tools like line wrenches and circlip pliers to do the job.
