H3 owners with a manual trans. Need some feedback

[Zach]

Yah this was before I found H4O, 3, 4 years ago. I researched and found part number, located it on the website. When I called the dealer to make sure, he told me I had the wrong one, pointed me at a $450 radiator. I thanked them and hung up, and ordered off the website for $200 cheaper It was the same radiator so I don't know? Local dealer told me $750, sheesh

$750. I just had pucker. Was that installed? I know the 2 radiators used to be 1k. Now have dropped to a retail of under $400. Thinking I need a spare lol

07 with 93K. I had the top crack @ about 55K (GM covered the majority of the repair). The replacement was the updated unit with the slightly redesigned top.

124K, 2008, zero issues. So, what's the advantage of using a manual instead of just using an external cooler?

if we use a manual one we have to use a trans cooler. Alrock mentioned that we havent heard of many issues with a manual rad cracking compared to the automatic rad

Not to rain on anyone's parade, but I really doubt there is a difference between the two. Remember there are far fewer manuals out there.....I think the take rate was around 6%.....so it only makes sense you would hear of far fewer failures.

Could be true, but I plan on ordering a m/t radiator soon since I've done the bypass and my current aftermarket radiator is a POS. Not having the trans cooler is one less area to fail (external fittings) and I save a few bucks in the meantime.

From what I've seen. Used to work for a Hummer dealership. The trans cooler side would let go and blow coolant through the trans taking the trans out. It still has the risk of letting go even if you did the bypass and external cooler. In that case, it would dump all the coolant out of the radiator possibly cooking the engine if you are not quick enough to stop. It takes out the engine. Just my opinion.
