Tannie temps

[xelaescal]

My name is Alex i have an 95 f350 OBS and I’m new to this fourm, i have a question on my trannie, my trannie runs fine but once i get to 180* it acts funny, i do a lot of stop and go driving, but i dive like an old man and don’t drive my truck hard at all. Why would it heat up like that, my trannie maybe has 10000 miles on it. what could be the reasons for this issue?
Thanks everybody for the help

Clogged cooler... if you had it rebuilt and they kept it running through the rad they probably didnt flush it...

i dont know much about trannies but how do you flush the trans cooler and is it hard?
Thanks for the help i really appreciate

I cant remeber what its called but you can get it at carquest or napa. Its in an aresol can, basically cleans out any of the gunk in the cooler.

If your lines are still running through your RAD, I DO NOT RECOMMEND FLUSHING AND REUSING!

Get an after market cooler. If you plan on doing alot of towing the I would go with the 6.0 cooler. If not then I would make sure its atleast a 10 row cooler.

The cooler isn't the best in the world, and depending on the ambient temp, stop and go traffic can get it really warm.
Also, since it's new, all the clutches are a lot more firm against each other and that can be another reason for the heat; more surface area and more friction

^^^^^ And the fact that you are circulating your fluid through a hot radiator...

A small cooler will run you like $50 tops. Trust me it will be a solid investment. Heat is what kills a transmission.

okay cool cause it runs fine all the time but when it heats up it wont get out of 1st unless i release the gas paddle, i going to get a transmission oil change and have my mechanic flush the cooler. i hope this is my problem, and thank you everybody for the input.

You might want to get your mechanic to pressure test your tranny. If you are having to lift your foot to get it to shift out of first when hot it sounds like you may have a intermediate seal starting to go.

sure thing i will ask him to do that, thanks for the help,

one more thing, where can i find an 06’ trans cooler, i would prefer new if possible, would a autozone carry one or should i go look else where.
