hello yall., im Darryl.. i have a 2013 Ramwhich the tranny is over heating at various times,,, it isnt consistant so far and it doesnt skip like it is about to go out,, but it will roar when it gets to 208... so far it has not went over 219 that i have seen ,, corrective action so far,,, i had it flushed and also the radiator flushed i dont know if they did the tranny cooler or not i will have to talk to people who did it to find out,,, i have been looking at the parts list on Mopar to see if it has a thermostat like the engine and cant find it listed ,,, i saw another post here of a 2011 that has a type of thermostat in it ,,, so my question is does a 2013have one too and does anyone knows b4 i tear into this

There is a H block type thermostat (I assume it's a thermostat) that can malfunction and not cycle the trans fluid to the trans cooler. Somebody with more insight should chime in soon. In the mean time, search the forum for transmission H block. I know I've read about it before.

This is the part that could be failing. https://www.mymoparpart.com/p/Ram_2016_2500/By-pass-valve-COOLER-BYPASS-VALVE-64-LITER-67-LITER-TURBO-DIESEL/64477782/68186711AB.html?partner=googlebase_adwords_parts_motor_make_model_year_ram&kwd=&origin=pla&gclid=EAIaIQobChMI7rafnIej3QIVRrjACh3JVAEuEAQYASABEgJkf_D_BwE

You can check by grabbing the 2 pipes coming out of it after driving a while. If the ones heading forward to the transmission cooler are cold, then it is stuck closed.

i see the H block on the mopar diagram but no way to purchase it ,,,

 

[Darryl Baldowski]

it appears the H block 2013 is the same in the diagrams as the 2016,,, but is not listed to fit it

 

[Darryl Baldowski]

update it was the H block,,, it is a thermostat basically ,,, easy to change and is the same as the ones on 2014 ,,, running great and holding under 170 now,,, thanks for the help

This seems to be a fairly regular failure on here. Wouldn’t be surprised to see a recall on this at some point. Saw the same warning signs with water pumps failing on here.
