What automatic fits a pre 1975 BBC?

Hi all. Will all modern GM automatics (700R, 4L60-E etc.) fit a 1968 396 big block Chevy? Is there anything special I should know before bolting one of these up? Honestly, this is the first automatic I will own. EVERYTHING else has been a Muncie or Richmond manual trans.

Thanks a million!

Well I'm getting ready for my 1st standard shift.

as far as I know a Chevy is a Chevy is a Chevy

There are 2 different flywheels or flex plate as far as tooth #'s :168 & 153 I think

Oldsmobile. Pontiac , Buick , Cadillac , Had a different Bell housing

BUT

Some automatic transmissions were Dual bolt pattern
& I've seen the OLDS Pont..... on a Chevy motor with just the 2 bottom bolts & the dowel pins

The 700 R~4 is a overdrive with NO Computer*

The 4L60-E & all that other{NEW}stuff needs computers.*

*{I'm 90% sure about the last 2 so don't hold me to that}

I'd first decide how much power you plan to have in the 396. The 700R4, 4L60 (newer version of the 700R4) and 4L60-E (computer controlled) should be able to handle the power if they are built right. However, you could also use a 4L80-E, which is the overdrive version of the TH400. There are kits to use the electronically controlled transmissions in non-computer cars.

If you want a low cost auto transmission, use a properly built TH350 (non-overdrive).

This site is for jeeps, but has some useful comparisons of transmissions.

virtually every rear wheel drive automatic transmission model GM made has been made with the chevy 90 degree bellhousing bolt pattern at some point or another

some were BOP and caddy pattern only though, and some were 10 bolt pattern and would fit all the divisions of GM

for more on this read up on wikipedia.com

lots of good info on this on there

heres one good page on wiki about this:

http://en.wikipedia.org/wiki/List_of...using_patterns

there are other pages of info on this subject on there


read this one about the transmissions models and info on them
