if you are NOT looking for OD then THM350 or THM400 would your best bet

The C20's were available with the TH400 originally. If you plan on using it hard, I would go with the TH400. If it is mostly a cruiser/driver, then a TH350 will work just fine. However since most C20's had fairly low gears, an upgrade to a 700R4 will keep the engine rpm's down and up your mpg's a bit.

captainfab I have heard lots of people say to go to a 700r4, why is that? arent they electronic and dont you have to have a computer or switch to run them? I have one in my truck but havent been able to drive it yet, the transmission shop said they made it so that I didnt have to have a computer, will it still work? what did they do to make it run without the computer?

1 question to ask and that is what are you going to use it for. if you are going to use it as a truck to carry loads and or pull a trailer than the 400 is more the trans to use depending upon your budget. if you just want it for going to church and driving around (highway driving) than a 700r4 would be the choice'
you could use an a/t column from the same vintage that you have or you can install a later model tilt column(not difficult to install)

NO,the 700R4 is not electronically controlled. The successor to the 700R4, the 4L60E, and the 4L80E are electronically controlled. The 4L60E and the 4L80E can be built as a full manual trans. When installing the 700R4, two things are very, very important. 1) the TV cable needs to be connected and abjusted correctly, as well as the carb connection having the correct geometry. 2) the torque converted lockup needs to be connected and operating. There are many, many, many threads in the 'Engine and Drivetrain' section about the 700R4 as well as the other 2 transmissions.
