420 transmission swap question

[Dave Bunker]

I am about to pull the trans out of my 420 and replace it with a rebuilt. Can anyone lead me to a string or web site that give you step by step instructions to refer to if needed....I am an old chevy and GTO shade tree mechanic and have had many trannys out, but not a Benz.....feel free and tell me what I'm getting into as far a degree of difficulty.

Also by doing this myself I stand to save $1000 in labor. The rebuilt is costing me $1500 from a place in SF. CA.
