Got the cooler installed a couple days ago. The thing is massive compared to the oem cooler. And so far my temps are down about 30 to 40 degrees even with the torque converter cooler on the side of the block still plugged in. Itís been unusually cool for May here in West Virginia. Usually our summers already started but itís pretty cool. I visited my brother in-law and sister right after installing the cooler and my temps the hole way up was 120 . Sensor is in the pan. Usually Iím running about 160 to 165 temperature was 65 out side. When I left it got real cool in the Morgantown area for this time of the year about 50 degrees and the hole way to morgantown my trans temp sat at 100. So it would seem Iím definitely going to have to install the thermostat in for the winter months. Even in stop and go traffic the trans only got up 130 . So the mishimoto coolor has helped a lot. I havenít towed or hauled anything yet but I expect the hay guy to be calling any day now .
Now unfortunately for the bad news .
Iíve very disappointed there was no instructions included . mishimoto just gives a link for a YouTube video. The video does show you how to install the cooler but makes no mention about the thermostat. I had no idea how to install the buy pass . It was 5:30 on a Friday so calling mishimoto wasnít an option. I donít see why a paper with a diagram canít be included to show you how the thermostat buy pass goes in. I put it in how I thought it went and got it wrong. My trans temp was only 20 degrees cooler then my coolant temperature and moved up at the same speed as the coolant did as it warmed up lol. That was annoying. So I guess what I did was I managed to buy pass the mishimoto cooler lol the front side of the cooler was very hot where the lines come in and out but the rest of the cooler was cool. I was really upset cause you canít get to the thermostat plug on top of the cooler because the radiator core support is in the way. I thought I was going to have to remove the intercooler and pull the cooler out to get to it. But then found out you can take the core support blots out and lift the support up an out of the way. I didnít even remove the blots on the passenger side, just left them lose. Pulled the support forward.
Once I got the thermostat plug off and took the buy pass out it was obvious how itís installed. I felt like a retard but got it right the second time. I also found out thereís a video showing you how to install the bypass but I wasnít able to find it when I needed it. My luck In a nut shell .
My other complaint is, Iím not crazy about the gun metal gray color, Iíd personally rather just raw aluminum or Polish even better black .
I also found out the lines are to long , mishimoto says to cut the oem lines 5 inches from the back of the hump on the stock cooler . If I did that that would have put the barb fittings and hose clamps right next to the radiator overflow bottle . There isnít much room with that bottle and the radiator upfront plus the boost tube. So I cut mine farther back so it would be easier to get to the clamps if they came lose or were leaking .the lines included were still to long I had to cut a few inches off other wise I would have had to stuff the lines behind the fender or let them stick up passed the core support. Not a big deal and Iíd rather have more then enough lines then not enough.
Now then to my biggest complaint, and this one was very disappointing. When I removed the thermostat I noticed aluminum shavings all over the thermostat and inside of the hole the thermostat was setting in. Iím not sure if thatís enough to cause a problem like plug a cooling tube inside of the cooler or even damage the transmission if it made its way back there. But I wasnít going to take a chance. I spent probably an hour and a half blowing the cooler out. Both in the Direction the transmission fluid would flow and reverse. I even when I was installing the lines purposely install. The lines backwards so the transmission pump would push the fluid backwards through the cooler and out into a bucket on the other side. I must have got it all when I blew it out with compressed air cause I didnít see anything in the fluid coming out of the cooler. If I didnít already have a filter filtering the fluid coming from the cooler before it goes back into the trans. I might have even just sent the cooler back.
Here some pictures of the doorman oem replacement vs the mishimoto
Over all I would recommend the mishimoto cooler itís leaps and bounds beyond the factory cooler. But I would definitely pop the thermostat out and make sure thereís no metal shavings in there before installing.
