I've encouraged people to rebuild their automatic transmissions and stick shift transmissions for that matter ever since I've done it myself for the first time and found out how terribly easy it is. I've said it once I've said it a million times if you're going to go through all the trouble of taking the transmission out and being the one to put it back in do not give the easy part of rebuilding it to somebody and pay them a boatload of money to do it....
