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.

What causes transmission fluid to overheat in 4L80E?

Overheating: Transmission fluid helps to remove heat generated from the moving internal components in the transmission. On the other hand, if a heavy load is hauled or towed and the radiator cooler can’t cool the ATF properly, it could lead to overheating of the 4L80E.
