I wonder what a tranny shop would charge for labour to install this .. any guesses? i would never attempt this myself

Bill and I have discussed this here:http://forum.gopowerhungry.com/calib...y-upgrade.html

What a tranny shop would charge to do this would all depend on:

If they are hourly>>1-2hours.
If they have a jobber rate.
How much they charge for the fluid. You should use new stuff.
