trevdogg67 My comments on thermostat delete are the same as there are no instructions with cooler. I had to look on this site to confirm proper installation.

I drove my truck around yesterday during the 90+heat stop and go traffic, no towing yet, and saw trans pan temps max at 155. Normally around 120-130.

I'll report back after I go camping at the end of this month with truck all loaded up and towing a boat over Mt Hood.

This is with only the mishimoto trans cooler, heat exchanger is deleted.

Well Iím glad I wasnít the only one . I guess the way I installed it the frist time I just buy pass the cooler [emoji23] cause my temps were only 10 to 15 degrees cooler then the engine temp and would rise and fall as it heated up and cooled off . Once I opened it up again it was obvious how it installs .

Think it would be better to be included in the installation video. But thatís just my 2 cents.

The cooler is a definite improvement over stock. Consistently getting 30 to 40 degree temperature drop on the transmission fluid.

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. It’s been unusually cool for May here in West Virginia. Usually our summers already started but it’s 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 I’m 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 I’m 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 haven’t towed or hauled anything yet but I expect the hay guy to be calling any day now .

Now unfortunately for the bad news .

I’ve 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 wasn’t an option. I don’t see why a paper with a diagram can’t 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 can’t 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 didn’t 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 it’s installed. I felt like a retard but got it right the second time. I also found out there’s a video showing you how to install the bypass but I wasn’t able to find it when I needed it. My luck In a nut shell .

My other complaint is, I’m not crazy about the gun metal gray color, I’d 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 isn’t 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 I’d 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. I’m not sure if that’s 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 wasn’t 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 didn’t see anything in the fluid coming out of the cooler. If I didn’t 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 it’s leaps and bounds beyond the factory cooler. But I would definitely pop the thermostat out and make sure there’s no metal shavings in there before installing.

Yeah Iím glad I was able to help him. I think he had a concussion. A sheriffs deputy and three ambulances showed up . They checked him out and recommended that he go to the hospital. His head hit the windshield twice. He also almost busted windshield out buy hitting it so hard. He also hit the steering wheel hard, air bag never deployed . He refused treatment and they told his son and his sons girl friend that show up, donít let him fall asleep cause he could go into a coma. He fell asleep 3 times . One time he woke up and was confused but snapped out of it pretty quick . Both his son and girlfriend and a friend of his was urging him to go to the hospital. But he wouldnít he wanted to help get the truck on the trailer .they threatened if he feel asleep again they would drag him to the car and take him lol . The girl did mention that he had been up for 15 hours . So Iím hoping he was just tired. One he was awake he acted fine . You never guess he was in a wreck. I hope he did go to the hospital later . Iíve been wondering about him.

I hope everyone has a happy Memorial Day and to all the veterans thank you for your service.

850 ford thatís a nice looking tractor , I googled that and the picture that comes up looks exactly like the tractor a guys friend had I helped pull his truck off the side of the road and pushed it up onto my trailer. He apparently got over to let a truck go buy and didnít realize the road dropped off cause of the overgrowth . Once he started to slide he said it kept going and he hit a tree head on . Totaled his truck that he had just finish fixing up, bent the steering linkage , bend the steering box and frame where the box attaches to the frame . I happened to be driving buy on my way to mow at a other property my family own and stopped to help him out , thankfully this happened very close to home . Pulled over off the road unloaded the tractor and used it to pull the truck out and pushed it up onto the trailer . Had to drag his truck through a field with the tires jammed and slightly pulling to the left . But thankfully the tractor was heavy enough it didnít matter. I could force the truck to go where I wanted it to go. But once I got out to the place he was staying at . His friend had a tractor that looked just like a ford 850 , we used it to pull the truck off the trailer . I wasnít having a good day that day and was in a bad mood , but when I saw his truck and got out to make sure he was ok I had to help him out .He couldnít afford a tow truck and wasnít sure how he was going to get his truck home. after helping him out I was in a much better mood and felt good I was able to help him in his time of need . When I heard his story and what was going on in his life, it quickly change my perspective and I realize yeah this guy is having a much worse day then I am , his wife apparently broke up with him recently kicked him out of the house . He now living on his friends property in a trailer , heís a handy man and was pressure washing a customers house and went to Home Depot to get cleaning solution for the washer and then he had the accident on the way back. He been working a lot of hours trying to make ends met and now he totaled his truck. Really felt bad for him. But at lest I was able to help
Him . I donít believe it was a coincidence it happened so Close to Home, and thankfully i was able to drive the tractor back home and park it once I got his truck up on the trailer. I wouldnít have been comfortable leaving the tractor near the side of the road so that worked out great.I was in a bad mood cause I wanted to get out to the other property but things kept coming up and I wasnít able to leave as early as I wanted to , then when I finally was ready it started to rain as I loaded the tractor up It wasnít supposed to rain that early ,I couldnít make my mind up on weather I should Just head out to the property or stay home. Then got frustrated and said screw it im going lol . But I believe the Good Lord had other plans for me that day . If I hadnít left when I did I probably wouldnít have know the guy had an accident and there for wouldnít have been able to help him out .

Also the horse with the Tyroid problems is going great . The vet said if he keeps doing as good as heís doing we might be able to take him off his Tyroid supplement and maybe not have to wash his hay anymore. That would be great and save a lot of time . Stupid expensive pets , the horses and chickens and ducks live and eat better then I do . They live in a liberal utopia where they donít work but I have to still feed and take care of them [emoji23] at least the chickens and ducks produce butt nuggets I can eat and sell so thatís something [emoji1787]

I was pulling nothing but the trucks own weight. My set up is Mishimoto front cooler, Derale with fan mounted below cab, all -8 AN lines, and bypassed liquid/liquid cooler. The transmission has a shift kit with billet parts in the valvebody only. I also have the Goerand GOV manifold and solenoid and a Goerand double deep pan. In the near future I plan on installing the Dieselsite remote trans filter. For trans temp display, I’m using the Edge Insight which I think reads somewhere atop of the valvebody.


Yeah the tractor has been a God send . I live on 65 acres about 30 acres or so is Field rest is wooded . We have two horses and ones sick . He has a thyroid problem and excess sugar will aggravate his thyroid and make him sick and his lymph nodes will swell Up as big as a Apple . So the vet said to chop the grass as low as possible cause low grass has less sugar . Also have to soak his hay over night to wash the excess sugar off. It’s a real pain . But with the tractor I’m able to keep the Fields mowed for him . It also big enough and heavy enough to bail Square bales and medium size round bails . I was disappointed to find out it’s made in India but I rather India then China . The sales guy told me that the parts are still made in the USA they just ship them over seas to be Assembled then shipped back. Have no idea if that’s true . Since it was made in India and to bring awareness to cultural appropriation. I have nicked named the tractor the mighty Ganesh [emoji57]

cultural appropriation and trigger words aside , I took the truck out today unloaded, had to make a tractor supply run. It’s very hot 90 plus and sunny and humid. Trans temp was running 150 definitely a improvement before I probably be 180 or so .
