Transmission coolers

Been thinking of getting a stand-alone transmission cooler for the T and not use the radiator cooler so I could clean up the trans lines. Is anybody here using a separate cooler for their automatic trans cooler? If so, what are you using and how much space does it use up? Just thinking ahead and trying to keep things clean...

 

Yes, I added a remote cooler and filter to my setup. The cooler is a "Derale 51908 19 Row Core Stacked Plate Cooler". The remote filter mount is a Derale PN 35729. Filter is not shown in the pics, it came a few years later.

The trans is a 200-4R. It's the same length and output spline as a TH350, so you can use the same driveshaft. You do have to relocate the trans mount. Four speed w/lockup TC.

 

Is this trans electric controlled.

 

No, there is no electronic control of the shifting. It's just like the 700-R4, it has the TV cable. If you want the torque converter to lockup, then you will need to supply 12v when you want that to happen. That can be as simple as a switch. The TC can be locked up in every gear except first, the valve body prevents this from happening.

I have a self latching relay, so I press a momentary button when I want to lockup the TC and the relay keeps it locked up. When I tap the brake, the relay drops out and the TC unlocks.

 

I used a GM map sensor with a relay setup on my 700r4. I also had a switch wired in to bypass it and manually lock it. The only time I didn’t like it was low rpm.. the cam profile wasn’t favorable but it worked well other than that.

 

So the 5v was enough to latch the relay? With a little electronic wizardry, you could have made that adjustable from inside the car.

NICE !

 

What are the benefits of lockup?

Thanks,

I am curious if anybody has used the derail long tubular type of coolers. I would think they would be pretty good if mounted solidly to the frame rail. I see they make several sizes length wise, and they are heavily finned. I read how good they were a few years ago but wonder if that was just hype or real word installations!

 

Lots of factors... the converter being one. Also overall drive train: how much stress is on the trans from the great ratio/hp match up and how hard do you run it... it’s not a issue on mine, three pedals.

 

Stock cooler (integral w/radiator) works fine on mine. Mild Chevy 350 with TH 350 and 2100 stall convertor. Do I run it hard? (Only when nobody's lookin'!)

 

Trans will run cooler, it's like having a standard trans at this point. The rpm will drop about 300, so I get better gas mileage.

Temperature is measured in the pan.

 

Putting a gauge on the output line going to the cooler will drive you crazy. The temps vary greatly, just climbing a regular hill on the highway will make the temps jump from 210°F to 240°F in a couple of minutes. You can see my sensor in the first photo of my post #2. I have mine in the pan now. They are always going to be higher there compared to the pan temps.

The bar chart above I believe was first done by ATI Performance Products , so I sent them an email asking where they took their temperatures. They said it was in the pan.

 

We used one in a dirt Super Stock car. It ran a 'Glide with no convertor, and we used a 30 inch long cooler. Three years with never an issue.

 

That’s the difference between older guys and kids... kids run em hard to get attention... lol. Me, I ran the pi$$ out of everything wether anyone watched or not, but I’m “older” now!
