Good point.What I mean of course is that it would not hurt this NA big block engine. Even a long climb would be say 30 to 45 min and that is it.
The transmission with a cooler in the 200 series (assume the 250 has as well) could be the reason you need to back off. Seems that is more so of an issue for the 250 series based on reviews I have seen.
The 250 doesn’t have a dedicated transmission radiator (cost cutting strikes again), and likely the biggest limiting factor when going uphill. The 250, even without towing anything behind it, struggles with (concerning) trans temps on long ascents.
The big weak link in the prado series so far is the transmission.
