xtremerevolution Posted September 10, 2007 Report Share Posted September 10, 2007 So I bought a heavy duty transmission cooler to install on my car. Just out of the blue, I figured I'd ask simply because of how easy it is to install them, is it at all worth it to add a secondary transmission cooler to double up the cooling power? Just curious.

I'd imagine it would be worth it to get the second one then. Quote Link to comment Share on other sites More sharing options...
Nick1234 Posted September 10, 2007 Report Share Posted September 10, 2007 i heard from the guys on zzp that heat isn't an issue with the 4t65-e, although i do know that you have the 60. no arguing cause i was supprised too and i also have one i was going to put on the impala Quote Link to comment Share on other sites More sharing options...

Oh shit for what you got you'll only need one....and if you actually do the L67 swap the 4T65HD won't need a cooler it does fairly well in the heat. You dont hear of many of them shitting the bed.

Its supposed to be rated for up to 10,000lbs towing on R/Vs and trucks, so I think I'll be ok. I'll take pictures when its installed.

Crazy K Posted September 10, 2007 Report Share Posted September 10, 2007 WHOA!!! make sue it is capable of fitting on the front of your radiator, othersie you might wanna get a smaller one. IMO the smallest size they have is just right for our cars. Otherwise, being the j/y rat I am.. I have only used used coolers I pulled from junk cars. 5-$10 from many yards. so 3 of my cars currently have one and only 3 more need it.

It looks nice too. I already took it out for a test drive and checked it for leaks and its all good to go. Here are the dimensions: Thickness: 3/4" Height: 10" Length: 15 7/8" It's an Imperial Econokool trans cooler, model 241018. http://www.partsamerica.com/productdetail.aspx?MfrCode=IMP&MfrPartNumber=241018 I hope I didn't go too far overboard, lol.

ManicMechanic Posted September 10, 2007 Report Share Posted September 10, 2007 I got an RV sized cooler for my L27/4T60-E....But then I have a Silhouette, lots more heat under the hood of one of those than a Regal...That and the TCS light keeps coming on.

You dont hear of many of them shitting the bed. Then how come a lot of L67 cars I've looked at has or needs a new transmission? Yeah I'm thinking the same thing... I hear most of these biting the dust between 130k and 180k miles. I had to rebuild my 4T60E at 148,000 because it had a bad shift from first into second gear under WOT (shift would lag about half a second and car would jolt pretty bad by the time the gear caught on). It would shift just fine under normal driving though. Either way, $1150 later I have a rebuilt transmission, and I'd like to make sure this one lasts me the life of the car.

I'd actually like to take a look at that, just for future reference and knowledge. I was under the impression that 9 out of 10 transmissions fail because of heat. At least that's what I've been told everywhere I've looked. The 4T65E could be an exception though. Quote Link to comment Share on other sites More sharing options...

ManicMechanic Posted September 10, 2007 Report Share Posted September 10, 2007 I know when I was looking for a dustbuster, 80% of them under $2000 needed a transmission. It gets REAL hot under the hood of the early U vans. Quote Link to comment Share on other sites More sharing options...
xtremerevolution Posted September 10, 2007 Author Report Share Posted September 10, 2007 http://www.zzperformance.com/grand_prix/articles1.php?id=23 Nice article. I learned a few good things from that. As for the 4T60E, even the cooler I have plugged in now heats up like a crazy mofo, so I know my tranny is running a bit hot. I'll have to re-check the connections I put in to make sure everything is tight enough though. Quote Link to comment Share on other sites More sharing options...

kuwaitliberation Posted September 21, 2007 Report Share Posted September 21, 2007 When you consider the air temperature is often over 100 degrees here in Texas, most of us have a tranny cooler. I have the very small GM cooler. Quote Link to comment Share on other sites More sharing options...
slick Posted September 21, 2007 Report Share Posted September 21, 2007 Yeah, that thing is huge. Hopefully it's not too big though. Quote Link to comment Share on other sites More sharing options...
xtremerevolution Posted September 21, 2007 Author Report Share Posted September 21, 2007 Yeah, that thing is huge. Hopefully it's not too big though. How would it be too big? On a side note, I was quite shocked at how soon the thing heated up. The radiator could be completely cold 30 seconds after the engine starts up, but the transmission cooler would be pretty hot. After a 5 minute drive, it would be too hot to touch for more than half a second. I would imagine it would be blistering hot without it, so I'm guessing it will do quite some good.

pwmin Posted September 21, 2007 Report Share Posted September 21, 2007 that was a pretty good writing. i would def put a trans temp gauge and aux cooler on 60's. Quote Link to comment Share on other sites More sharing options...
xtremerevolution Posted January 9, 2008 Author Report Share Posted January 9, 2008 Bump for Adam. This thing isn't very difficult to install, but you have to know what you're doing before you start. As it is, your car's main radiator on a w-body helps in cooling down the transmission. There are two metal pipes coming out from your transmission into your radiator. If you're facing the front of your car, the pipes will come in on the left side. There will be one going into the top and one going into the bottom of the radiator. The top one is the inlet, and the bottom is the outlet. The point here is to have the outlet from the bottom of the radiator go into the transmission cooler, and the outlet from the transmission cooler going back to the metal piping to the transmission, so you basically have both the main radiator and the transmission cooler cooling your transmission. In warm weather, this method will help further cool your transmission, while in colder weather, it will help control your temperatures so they don't go too low by running the fluid through a hot radiator before it goes to the transmission cooler. The size of the transmission cooler you use is entirely up to you. I opted for the largest one I could find because my engine produces a lot of torque and I drive it like a grandpa on crack and viagra. One very important thing to pay attention to is the way that everything is connected. The transmission lines go into the radiator through a male metal fitting. When you pick up your transmission cooler from your auto store, make sure to also pick up the GM transmission line fittings, which will a female fitting made to fit with your male transmission line fitting, and an additional male fitting made to fit inside your transmission where the original transmission line used to be. I'm not sure how everyone's radiators will look, but I ran my cooler's lines around the side of the transmission cooler. Its a bit of a tight fit in there but they should go through just right and end up right where you need them. Mounting the cooler basically consists of 4 ziptie-type strips of plastic that you push through both the transmission cooler and the radiator, and attach a locking piece at the other end and cut off the remaining strip. If you look closely at the pictures I posted earlier, you should be able to see what I'm talking about. This part can be a bit tricky because you have to mount the cooler in a place where you can reach the other side, while avoiding the fan blades. Past this, the instructions in the box that comes with the transmission cooler should be all you would need to install a cooler in your own car. Let me know if you guys have any further questions or anything else to add to this. Quote Link to comment Share on other sites More sharing options...

Guest GrandPrixlover1 Posted January 19, 2008 Report Share Posted January 19, 2008 does anyone know where I can find what kind of transmission I have on my 96 Grand Prix SE Coupe? Quote Link to comment Share on other sites More sharing options...
