No.
same bolt pattern if the 4l60e was behind a v8 or 4.3and the th400 was from a chevy and not a (bpo or caddy )
Sure, preferably a short tail TH 400 with the Chevy/Buick bolt pattern.
they are not maintenance adjustable on the th400
as long as it is a chevy bolt pattern th400
It can be done, yes.
Automatics would include th350, th400, or the 700r4, if you want a overdrive.
just about any Chevy trans, a TH350 or a TH400 are the most common and will both fit. as far as engines and transmissions with Chevy's there just about all interchangeable without to much messing around. only difference with a TH350 to a TH400 is that a 400 will take higher horsepower/torque. but for most stock applications a TH350 will be fine , oh and the TH400's are slightly longer to.
you can purchase an atsg manual, ron session th400 book or other print. google search for it or go to helpwrench.com and find an exploded view if one there with diagrams.
1 and a half to 2 qts
4L60E, (the electric decendant of the 700R4 and TH400)
Most likey its the TH400. If it has 4 speeds, its the 700R4 (w/overdrive)
Yes, It is not even close. It will not work.
