Is the GM 700R4 a heavy duty transmission?
The 700R4 was a pretty tough transmission, but not quite in the class of the TH400. GM needed a heavy-duty automatic overdrive. GM used as many TH400 parts and designs as possible in the 4L80E, but the added overdrive gear would require an extra gearset and slightly longer (~1-1/2″) case.
