okay, time to venture into the world of automatic trans. my local used parts yard is having a half price sale this weekend. i was thinking about going for a chevy automatic overdrive. i have several questions.

1. what is the difference between 700R4, 4L60 and 4L60E? is there a difference?

2. is there anything i should watch out for good or bad while i hunt for the perfect one?

3. are they somewhat easy to rebuild? an engine is relatively easy for me..

4. is it better for a transmission shop to rebuild my find?

i have installed several in the past and have learned the steps. i will be putting this in a 64 pickup. i have read in this site about good books to buy and will probably get them whether or not i do the rebuild.
now that i have said all that, what are your opinions of rebuilds from the local auto parts store? good deal or someone elses problems?
thanks for any info.

answers:
They are essentially the same transmission, just updated versions and version number designations. 700R4 had 2 versions, but basically go for anything in an 1988 or later.
The 700R4 came first, then was updated in 1985, then in 1993 it was given a more technical name designation 4L60 (4-speed Longitudinally mounted 60 series transmission), and the E was added to it later when it became electronically operated.
