ATS trans cooler bypass valve

[RVTRKN]

Does the device you purchased actually block the bypass? The term "installed the bypass" reads that your bypassing the cooler/heat exchanger. This device, I assume, actually removes the ability to bypass the heat exchanger, causing the flow to allways flow through the heat exchanger? I don't like the fact it will cause longer warmups and even cooler than designed temps under normal driving temperatures. Is there an aftermarket bypass that is more reliable than OEM that performes the same function? It would be nice to have an adjustable temperature controlled bypass for extreme cold climates.

It allows flow from the trans through the cooler at all times. I live in Louisiana so extremely cold temperatures are really not an issue.

It doesn’t need to be extreme. The trans does need to warm up thou, and you have greatly delayed that action.

Just went for the first drive with the valve installed. Warmed up just as quick as before, 84* right now outside. Temp settled at 147*. That is a 20* decrease. So is it worth it for me, I really don’t know. But warm-up did take any longer than before. But when we have our “3 weeks of winter “, it may take a little longer.

Had a Banks trans temp gauge. 2011 got stuck in slow traffic, uphill, 6% grade for 2.5hours. Chk'd later & trans fluid smelled different & changed a little color. NOTE: later told ATF+4 formulation doesn't "look burnt" like the legacy fluids when cooked.

Return trip home almost same thing happened elsewhere in PA. Both times exceeded 230 deg. After a little research I decided on installing the following under the body, directly below my seat, as it were. Fittings were Parker Push Lok, using Red hose for hot & Blue for cooled. Note the Winter By-Pass valve I found on their site. Good luck.

EVERYTHING........if you are a retailer like ATS or RevMax

I put ATS and BANKS in the same box.

Depends on the climate you live in, even then it will take longer to warm up and my 0.02 is that’s not good.

I’m still not certain it’s a real issue, but rather a marketing gimmick.

I think adding a thermostatic bypass to the trans was a big benefit over older transmission cooling systems.

There is a reason thermostats are used for many different applications.

The 47RE has a fluid to cooling water tank, to help get the transmission fluid to engine cooling water temps quicker. Seems they wanted the fluid in the 180 degree range.

I set up a cooler for my G56, as it has gotten up to 250* at only 15K GCW. The heat exchanger is the OEM auto trans cooler, that fits both manual and auto equiped trucks on the radiator. The bypass is still active, and I plan to leave it that way. I manually run a pump, when the G56 gets up to 180*, cooling it down to 160*, so the bypass is not necessary.
