Finally bit the bullet & bought something I swore I never would, That being IMO an overpriced oil. But anyway, put Amsoil ATF on the truck last Fri, Didn't drive it too much over the weekend considering the front end work that was going on. Looked over yesterday @ the trans temp & it was 167, that was after crusin unloaded on the interstate for bout an hr. Before with "normal" fluid only time I seen temps that high was pullin heavy in stop & go traffic. Normal crusin temp before was never over 130. Anyone else seen their temps go up after putting Amsoil in?

 

I use Amsoil in everything I own. You should not see temps that high running empty. It is NOT the oil, you have some other issue that needs addressed.

 

same here, I run Amsoil in everything, I did run higher temps, after tranny build my tranny temps have dropped back down.

Normal range is 160-180F anyway.

double check your rad, most times inbetween the intercooler and rad its completely blocked with dirt/oil, (tranny is also cooled via tranny cooler on the pass side of the block)

 

here is something to read with reguards to normal trans temps:

Double check your fluid levels, too. Truck parking brake on, shift D,R,D,R,N, then check fluid level while running in Neutral....

 

I am with these guys, I have Amsoil in everything I own, That would be 1 Dodge 2 Mercedes and 12 or so tractors. Amsoil actually invented synthetic trans fluid. I have never heard of it causing the trans temp to go up, on the contrary always down. Has to be something else. Oh if you compare Amsoil to the other synthetics and their 5000mi drain intervals, it's a bargain.

 

Another AMSOIL cheerleader here! I've been using it for 20 years in everything!

 

I know I'm in the safe range with regaurds to temp. Sender is in the Mag-hytec DD pan. Just find it odd that in the 38K miles since the DTT trans never saw un-loaded temps that high running plain ole ATF, but a day after switching to the best you can get, temps go up. Also noticed today it seems to get warm quicker. Will say I do love the way it shifts!! Alot smoother. Will be pulling around 17k tomorrow, so we shall see.

 

I'm not an Amsoil fanatic... but I do love their ATF in my DTT.
In clear air I never see hwy temps over 130-140.... even in the summer, over 100* OAT..

Worth double checking which Amsoil auto tranny fluid you have. Make sure it's producy code ATF?
They also have ATL, ART, and 2 or 3 others.

Anything else different this time around? Different filter? New temp probe? etc. Also, What front end work?
You changed more than one thing at a time... always possible something else is making the engine work harder?? Just guessing here.

The jug says ATF on it.

Nothing different WIX filter that Amsoil guy sold me, same probe.

Front end work was just all new ball joints & new unit bearing only on drivers side.

Pulled the little trackhoe around yesterday, Crusin on the interstate for close to 15 miles temp actually staid around 155, "with OD off". But once I got on the little roads got up to just under 170..Then once in the steep devolpment it got to 190. But was expecting that as this place is ridiculous steep. But same roads with same trailer & load before changing 175 was the highest I saw.

Another interesting devolpment, after unhooking this eve, on the 45 mile interstate ride home it never got above 145. Which is 20 degrees cooler than the same trip monday. Also swear my converter dont hold as well either, seems to "flare" some now, maybe I'm just paranoid. But so far this is the first "mod" I'm second guessing myself on!!

 

Very hard to evaluate subtle differences with the temp probe in the pan. Especially with warmer weather showing up?
Don't know the WIX tranny filters.
DTT recommends the filters from the 97 CTD's. Claim they are better than the 24v filters.
If Tim did your DTT, you might ask if that could be the difference??
I'd give it some time and just keep an eye on it.

 

I don't consider a 20 to 30 degree change "subtle". Power by poole did my trans. Will give him a shout about using the earlier filter.

From what I've gathered this week 150 to 155 seems to be my " normal " operating temp now, VS 125 to 130 before Amsoil.

 

That is where mine runs too. I think you will be fine there.

 

I think that you have gotten use to the winter tranny temps and now that the weather has got a little warmer you may be paying more attention to it due to the fact you just changed it??? If you say that your TC has been slipping a little that will also aid in higher temps. As long as you are not getting above 200 you are fine, expecially pulling a heavy tractor up a steep hill going 55 or less. Be sure to check your trans cooling system. If you flushed the tranny to install the AMSOIL (which I'm sure you did) you could have moved some gunk in to the coolers and have caused a small obstruction. Good Luck and trust me...the AMSOIL is the Best You can Run PERIOD!

 

As I said in an earlier post, Trans was built 38k miles ago, in 07. And even in the hottest part of july the highest I would see was 165. That was stop & go traffic for 2 hrs pulling 12k with air temps over 95. While "normal" summer cruising temp was around 140. Seems to me this oil responds faster to changes in condition, in reguards to air temp,conditions & load pulled. But also seems to cool down faster, which is a good thing.



Reguardless going to talk with the trans builder in the morn about the filter and see what his thoughts are.
