940 rebuild... should I?

Wow ok so I should get really good at these and do them for 1/3 of that price and have a nice side income.

Just for kicks I looked on jegs and Summit and they have them new (refurbished) for 1,000 to 1200 with a warranty for crying out loud
You should go ahead and look up what a rebuild kit is on Summit? Or a transgo stage 2 shift kit?
And don't fall for that having to buy crazy special tools bologna! You can make the tools you need at home.
