Mounted like so,


Would it hurt and or, could I run another cooler in series with this guy? Or, do you guys think its up to the task?

I have a cooler just like yours & it keeps everything around 170-190 till I start running it hard or in stop in go traffic I have seen 210.

Whats a good operating range for a built 80e?

If its a plate cooler then Y them off. Two in a row adds restriction to the fluid flow.

Gonna buy this guy and attempt to mount up front.

So I run the coolers in series or in parallel?

Parallel. Y them.

Sits at 190* in stop and go traffic, falls down to 170 area when cruising.

Eh?

Bumping this back up.

Jakes level 2, what kind of temp should I worry about? I got told lower than 190* but theres no way its gonna sit below that in stopped traffic.

Before I add another cooler in the system I would like some more input.

The trans temps should be inline with or lower than engine temps 190 in stop and go traffic is not that high you are right where you should be IMO.

Would adding a large cooler like a 70274 hurt any, or could it only help?

It will not hurt anything but you need to ensure the cooler you use does not create a restriction.

I'm running a hayden 679 in front of the a/c condenser and bypassing the radiator. The highest temps I have seen from my 60e sensor that is installed in the pan is 160. And that was only after my converter kept unlocking at interstate speeds. I normally don't run over 140 so long as I am reaching lockup speeds. Stop and go will sometime get it up to 150 or so until I get back to cruising speeds.

That is, I am assuming a non-built 60e, where as I have a built 80e.

My old stock 60e used to run the temps you said, which is why I am concerned with the current temps

I don't really see how having higher quality parts in the transmission is going to appreciably increase it's operating temps. You do not mention if the existing cooler is in series with the radiator or if it is bypassed. If it is in addition to, then that will cause the temps to remain on the higher side. Also, the cooler you are using is tube and fin which will not cool as well as the plate style. Having it mounted on the underside of the car like that, it is not likely it is getting nearly as much airflow as one mounted up front would be as the air dam is re-directing most of the flow.


Just a couple seconds of searching turns up this thread from a couple months ago which has similar sentiments.

I am used to allisons and they run hotter when built from higher line pressures etc.

I am gonna add another cooler up front, the couple hundred is worth it if that prolongs trans life.

Stock "cooler" has been long since abandoned.
