Tranny over heating while towing


Recommended Posts

Posted

The electric fan replacement won't give you that much of temp decrease. I've had dual 6500cfm setup on my rig for few years now and it has kept me @ 195 engine temp and 175 tranny temp but I still go over 200deg while towing with stock tranny cooler

I know my temps. stay that cool because I monitor them with my bully dog gauge/tuner. I have all brand new lines, radiator, auxillary cooler, and my tranny has a fresh rebuild on it. Last time I towed, I had 5000lbs. and it was 85 outside and my trans. temp. did not exceed 170, and that was stop and go. When I go and park the trailer I let my truck idle for a while and I have had it drop 40+ degrees. I have not seen 200 degree transmission temperatures since I replaced my lines and all that other good stuff

Chawkins6789... Is that one pictured a direct replacement? That's what I am looking for, I just want to bolt on a more efficient one

 

 

My new one? Hell no, It uses AN lines and I had to make my own top bracket

Not sure how long you've had it installed, but what are your temps. so far?

Usually under 150* cooler if I turn on the A/C and those E-Fans kick on high

I have all new lines too. My truck has 80k mi on it w/stock rad and cooler. I always have issue when I pull trailer around all day.. I see temps bet 180 (usual) - 220 and it's not even really hot out yet

I don't know what to do

Nice. If I keep my tranny out of OD that's normally what mine stays at. Whenever I save enough money, the 4.88 gears should keep that temp. about the same :)

Have you tried an aftermarket cooler? Not even my stock auxiliary cooler kept temps. that warm while towing the same load. Also, keep it out of OD. I don't use tow/haul mode anymore, just keep it in "3" the entire time. It makes a world of difference while towing (keeps rpm's up). It sounds silly, but it definitely worked for me.

Bigger cooler, I can help locate one for you and get you what you need to install. Maybe not like I installed running all -6 line but the adapters for your factory radiator

no I don't have an aftermarket one that's why I started this thread I never knew that about the tow/haul mode seems like I've always kept in overdrive while I tow

yeah that's why I started this thread I've been trying to find a good replacement for my cooler factory one

Hey, you gotta admit, I do have a Bitchin' cooler. Tooch, you want to upgrade and dont mind spending a bit of money(not as much as I did) get with me and we can find you the perfect cooler

Give me your needs and your budget. Some things I may have to deal with in PM because of discounts I get places. but I need basic info. What you tow, engine, how often you tow, and driving style

I have the 6 liter gas engine I tow a 12 foot trailer for work most of the week. Itis full of tools (I'm a GC). I'd like to keep the materials around a hundred bucks

 

Pm me of you like

or email me

$100 wont buy you that great of a cooler(compared to mine lol) I would go with this for your needs

I get it about $20 cheaper from them and I can find your fittings if you want to go this route. If not the B&M 70266 is cost effective but not as great as a cooler, its the thicker version of my old cooler. I can get it for around $75 and find fittings for you as well if you go that route.

 

I hot rod my truck and want to save the poor little 4L60E. I also tow a 16 ft horse trailer. So I needed a lot of cooling with the 6.0 spinning the 60E

    • I wasn’t commenting on your post. Certainly wasn’t arguing. I was making an observation on my long term experience with supposedly proper length of driving for proper heat cycles. Works for me. Although I have seen water or vapor come out of exhaust when vehicles weren’t run very long and shut off. It’s very humid in the morning. Then hot and humid. 
    • Not what I said but I can work with it anyway. Complete combustion produces CO2 and H20. When it's cold enough you can 'see' it as water vapor but it is always there and more so the better the tune up. It's physics, not an argument. In a cold motor when the cylinder jacket is below the condensation temperature the water goes to the pan and not the PCV system. Heating the oil moves it from liquid to vapor where it is removed by the PCV system. When and how much depends on temperatures. Of the air, the water and so on. It has little to with the humidity. Water is a combustion product.  
    • I can only guess as well that something was clicked on that brought you to the half ton choices by accident. By all means try again and chose the 3500 and sort out that its the cab and box configuration you want and choose four wheel drive ( rather obvious to have a transfer case ) and to make sure the dually isn't chosen. I find or at least did a couple of years ago when I was sifting through the options that it would sometimes jump ahead after choosing the series of truck and in this case 3500 and skip some of the other initial configuration choices and have to watch the heading bar and sometimes back up by choosing the first in the series of option break downs. I think sometimes the computer will remember items that were last chosen and skip over the first part. Anyway go through it all and depending on the trim level chosen and I think the LT is one that may fall into that where the option of having the 4 high auto transfer case can be chosen, where as a High Country doesn't show that option as it just comes with the fancier ( not necessarily better though in terms of potential problems ) transfer case but for sure both transfer case choices are equipped with high and low range in the HD truck segment. Like Newdude said who works at a dealership, its the half tons that are the ones that will come with the single speed unless certain options or trim levels are chosen that add the two speed transfer case but as your looking at an HD, you don't have to worry about that hot mess.    One item that at least didn't show up and not sure if it does yet or not in the HD options on the manufactures pubic website is the upfitter in cab switch option if one is desiring that. Unfortunately its not wired in at the factory but the panel with the switches is on the dash but the wiring harness to be installed gets tossed under the rear seat to be installed by whomever after the fact to complete the installation. 
    • Yesterday we brought home a 6yr  old Havanese dog from a nearby SPCA.  We've had her for 24 hours and we are delighted with how well she is adjusting to her new home.  It  was a huge decision to adopt a dog at this stage in our lives but we believe we made the right choice!   it was reported that her first 6 years were ones of neglect.  I think she's already realizing her life is going to get a whole lot better...  so is ours!    
    • I thought I was building a HD 3500 srw, maybe I was lost.
