Tranny overheat

[dickdowd]

1985 300z with tranny problems.

We have a project car that fried it's tranny. We found a used on and replaced the dead on. Then the same thing started to happen again with overheating the suspected problem. Stopped by a tranny shop an they said this was a common problem with Zs. They said to change the radiator as they failed internally. We got a new radiator and are about to put it in. Would it be wise to add an aux Hayden cooler? Are there other problems we should be looking for?

Thanks,
Dick

On the older Z i have heard of the trannies overheating and failling but not that often. But I dont deal with many Z31s, but to answer your question yes it would be wise to add a tranny cooler.

I use a big trannie cooler and a engine oil cooler.

Where and how did you hang them? Space seems limited, but I haven't looked for a place yet.

um...on a z31, probably would have to between the radiator and the clutch fan...somewhere in between there, unless you want to remount the radiator. i have one to install on mine but i havent really looked on where to put it in at...
