I installed a bypass trans cooler on my Escalade because I live in Arizona and would operate 20 degrees higher than normal operating temperature. Now that it’s bypassed, it runs at the correct temperature even in the 110 degree summers.
I don't care how big your cooler is...your transmission will never run too cold. Oh, if it's 30 below zero, when you first start the vehicle...sure it will run too cold for a few minutes....but, not for long
No need to bypass in the winter. Minnesota here, 210k+ on my trans and I got a big 11 x 11 hayden cooler, bypassed the rad for the last 7 years, never a problem.
or just place a cover over the cooler, the Radiator cooler works both ways to strip heat and transfer heat so it can also warm the transmission oil in the winter, but will have to watch the temps and see where they go
All alI know about the inlet and outlet lines, is that the inlet to the radiator is from the bottom, in order to kick out all the air from inside, and the outlet is at the top of the radiator.
If your TC has a thermostat in the condenser u should in line new cooler after ur condenser , that way no matter what ambient temps are , the TC will always keep the warmed up oil temps to operate correctly which in return the new cooler will keep ut from not going too high ,,,
Hey. Bro I put a thurmstat on my cooler. So when it is cold it runs throw the stock rad to wome it up then when it gets to 160 it opened and lets the fluid go to the cooler. Works like a champ
I saw those too. The only problem with that is 180 degrees is much warmer than the transmission needs to run. It's clearly not excessively hot, but with heat accelerating the degradation of everything from clutch packs to rubber seals, I'd prefer to run the transmission only as warm as necessary. Someone should make a lower temp thermostat that opens at around 120-140 degrees, that's still plenty warm. For people who don't want to use a thermostat for whatever reason, covering or partially covering the cooler during the winter can be an option too.
was just thinking about installing a cooler on my future daughter-in-law's '15 civic because it has a CVT, & u do know they r not good wen u hav 80k... i also use & sell AMSOIL, so between the 2 i believe it will add long life 2 that trans... can't believe the drop in temp... liked the vid, good job my friend...
Beautiful seeing those temps drop. I have the same radiator, engine/trans, in my 06 TJ and my transmission temps are a lot more than I'd like them to be and it's not even hot out. Might have to give this cooler a try.
@@user-gb1ne5jj8v nah, it needed a cooler 100%. I am at a much better temperature now with my Hayden 689 installed. I was hitting 220 degrees on a cool spring day before just driving on the freeway, this is a fresh build mind you with only a few hundred miles on the new oil.
@@user-gb1ne5jj8v I think you are jumping to conclusions. 220 is certainly on the hotter side but that's not really indicative of a bad transmission or bad oil. That means the transmission just isn't being cooled properly.
The drop in temperature with the cooler installed was mainly caused by colder air hitting it at 60mph. The fan on that cooler isn’t going to be of much help. The large hub of the fan covers most of the surface area of that cooler; barely any blade coverage. A fan with a much smaller hub would be better. Ever stand directly under a ceiling fan and notice that when you step to the side a little, you get more air blown on you? Plus the two bars also impede what flow that fan will provide.
Thank you. Straight documented results. No flawed theory or BS discussion - just before/after comparison. Well done. That said, many modern systems run with a small 'thermostat' that must be bypassed, like in my Crown Vic. Thermostat bypasses the cooler until it reaches 180 degrees or so. There are kits to eliminate the thermostat, which I have done AND added an additional cooler. Other systems utilize engine coolant in a heat exchange unit such as in my Jaguar XK. In that case I replaced the factory cooler with a heavy duty unit and eliminated the transmission coolant loop from the engine cooling system. Now they're completely independent and have fewer failure points overall - like a normal, old fashioned car.
Whoa my cvt on my Altima would run 240 and after the cooler it’s at 230 I changed the trans fluid and filters and still nothing tried 2 different ways to run transmission lines
It's a hayden 676. Personally I'd opt for the 697,698,699 internally bypassed coolers instead if you live in a cold climate. They're only $50 @ rockauto
Others are buying factory cooler with four tubes and install together with aftermarket transmission cooler, and others just disconnect pipes from the current installed factory transmission cooler and take the pipes from the after market transmission cooler and connect it to the return hose pipe and the inlet pipe of the transmission direct. What is your opinion, what do you think is the best? ?
You can buy a fan kit that puts a thermostat in line and will only work if it gets over a certain temp. I have one that turns on at 180 and off at 165. I bought the kit from AMERICAN VOLT on eBay and its worked well so far. They also sell different rating thermostats to turn on at lower temps or up to 210.
I have a 2007 dodge 2500 Cummins 48r factory large transmission cooler it has a bypass built in. It's like a cheap 40K cooler. They go for like $120 or $10 at a pick a part. Keeps the 6l80 under 165f towing in 110f ambient. Never seen higher than 170f doing some hard wheeling under 10mph.
I have a trans coole twice that size on my 14 tacoma...it cools about 20 degrees here in az hear ....i wont believe that little cooler will drop temps 60 degrees....lets go brandon🤡🤡🤡
i have a 2014 jeep grand i drive on the beach you think i should install it to on the beach its hotter and i you air down to 12 and drive in 1 low 4x4 ,,,,,ty i like ur video by the way
yep great job, but only really good if towing or racing or heavy duty work for the transmission ,still a good external trans cooler will help extend the oil life and the transmission as well. :)
Was your transmission overheating? I have an 08 patriot and just on normal driving on the interstate for about 35 minutes and I get a trans temp light and the car gods into limp mode.
