the zf5 swap is finally done!

what's the advantage of a ZF with a short throw? I've never had a problem with mime when I needed to jam gears.

Easier for the daughter to shift when driving me home from the local pub!!!

Also pictures of the cooler(s?) if possible? Is it just a big heat sync? I would be interested in making something like that work for my NV4500.

Here are the ZF5 coolers.

save your money. I've never had a failure on a ZF5 due to overheated trans.
I'm grossing more than twice of what most lug around. F450's are usually lugging around 15k-21k if you expect to make any revenue. trans never complained. the ZF6's are a whole different animal. They do need external oil cooling.

I'm not buying them, he is working on an NV4500 and wanted pics for ideas! I just keep a diesel favorites folder full of junk...when I take the time to name it, I can find it, otherwise, it's a crap shoot! Someone posted them on here, I saved the link figuring someone would want it later.

i also had a guy from another transmission shop and parts warehouse, zumbrota bearing and gear, tell me to get some coolers. he was not trying to sell me anything. he said he has seen a lot of overheated zf5s come in. i look at it as a better to be safe then sorry. plus, this tranny has hellacious roll over noise. did i hear something about this meaning the tranny is weak and needing a rebuild. it takes about a 1k in rpms for it to go away.

i have physical proof from my carrier. three transmissions with a total of 890k chassis miles. One died due to a leaky PTO, the second due to a cracked bellhousing/case. It's currently on it's third. if they're getting overheated, there's something very wrong with someone's driving.
