Question Tranny Got Hot...now what?

j:

you best give a call to brian at BTS and ask him kindly for his advice.

iirc- what he advised me to do with my 2000 4R100, is run PLAIN JANE Mercon through it and change the fluid and filter every 30k per the book. The stock clutches don't like the slipperyness of the synthetic fluid.

i am not saying that your tranny is toast, i am saying talk to the expert.

my 4r100 with the 5r100 cooler barely blips on the temp gauge.

Yea ive def heard that too. I go back and forth between the synthetic and conventional...never know what to do cause the synthetic disperses heat better.

Have you ever had your tranny under a serious load like i did with that cooler in there? How did it respond? How difficult of a job is it to get that 6.0 cooler in there?

CALL a reputable tranny guy like brian and talk to him. he can explain it to you better than i can. after talking with him and thinking about it, for my needs, i DECIDED to stick with conventional fluid until the day i need tranny work done. hopefully that day is far away. remember, i am a person of a technical background so my mind works different then most.

did you loose any fluid? if so, how much? i'd think that at worst, you burped the front seal on the pump. top off and monitor it.

load- 2 up bumper pull horse trailer, 2 horses, fresh fluid, 60-65 highway then into hill country the gauge never gets above 180. lets say i was a little heavy. truck grunted, but never complained.

it fit fine. but you have to do some southern engineering on the hoses. you need to adapt from 4r100 3/8" lines to 5r100 lines at 1/2". bolt holes all line up. but i put it in when i yanked the IC so i had plenty of room.

yes i think i need to call a reputable tranny person...cause the guy i had mine serviced at last (which i deem reputable becuase he built one for my uncle that is just unbelievable) pushed for royal purple real hard.

didnt lose a drop of fluid. fluid looks ok, smells ok, level is fine.

yea you got me beat...

i can do that...but what about the auxiliary cooler on dieselsite? looks to be a bit easier? will it be as effective?

which one? the v10 one. look at how big the 6.0/5R100 one is than the 7.3/4R100 one is..

7.3-6.0 Trans cooler comparison

what do yo think?

the v10 is in between these two.

sweet jesus!!! the one i was referrring to was this one.

thats pretty impressive. if all you have to do is some custom hose routing (and the hoses are rubber)...it couldnt be that bad right? How does one go about removing the factory one...for that matter how in the heck to you get that I/C out of there?! That looks like a task!

Another recommendation for the 6.0 Cooler. It isn't that hard. Give BTS a call and they might have a "kit" for you. It would be easy to tell you what needs to be bought at Home Depot and the auto parts house.

A Rant if you will...

Well I finally went to meet up with the guy that was going to sell me the tranny cooler from a "6.0." I'll be darned if i dont go and meet up with him and find a cooler sitting there that is NOT from a 6.0!!! It looked identical to the one i had in mine. He swore up and down that the cooler is inside the the radiator. Funny thing is, the guy knows what he's talkin about because he was talkin about the motors he's swapped out.

Correct me if I'm wrong here, but he is partially correct. There is indeed one inside the cooler, but there is also the external one. The 6.0 is significantly larger than the 7.3. The one he had was identical looking to mine so I know it wasnt right. Sooooooooo going off of DP's post with comparison pic, I'd say I've got the wrong cooler, so I didnt buy it.

Where can i buy another that is correct?
