Transmission Cooler Kit

[Baconbit]

The MM did not come with a tranny cooler correct? Is there a particular aftermarket cooler that is better? Or a style that is better? Is the radiator style or the finned skinny dual pass cooler better? Looking for suggestions. Gonna have my front bumper off and I wanna add one just not sure which one and might as well do it while the bumper is off.

The Marauder came with a cooler from the factory. Some have added an additional cooler in series with the stock cooler. You can't go wrong adding more cooling for your tranny.

^^^^^what he said, heat is a trannys worst enemy!

[musclemerc]

Keep in mind the MM came with a very efficient plate type trans cooler that also has a thremal loop built in to it.

[ctrlraven]

I added a aftermarket one in line after my stock one.

[Baconbit]

Ahhh ok did not know that. So then there really is no need to waste the money on a cooler if it already has an efficient one.

[dbc1965]

B&M cooler will work great.

[musclemerc]

I never said it was a waste.
If you do it correct and plumb the thermal loop properly then fine.

[Baconbit]

Plumb the thermal loop? I thought you just mount the cooler and run the lines? lol

No, Casey and a 12 pack of KY is!!! :D

[fastblackmerc]

As I said, plumb it in series with the factory cooler. I hooked up the output of the factory cooler to the input of the aftermarket cooler.

[boatmangc]

Has any one logged trans temp differences before/after an additional cooler was installed?
I just did a 200 mile trip in 90 degree weather and watched my trans temp stay at right around 200 degrees at 85 MPH and went up rapidly if I sped up.
Just curious.

Gary,

I put a deep pan on mine and with 2 extra quarts and it takes a little longer to reach temp but ran no cooler so I installed a small auxiliary cooler and it runs about 5 degrees cooler.....maybe!!??:cool:

When it's hot it sits right on 195* at 75 MPH and at times it will run at 200*......about the same as stock!!:bandit:

[napolitano]

Wow, I never paid much attention to the stock temps for the tranny and cooler. i now know with the additional cooler, deep pan, aeroforce gauge and the hotter than balls florida 95 degree weather I drove in from 9am to around 2pm. tranny temp never went over 180. It usually stays around 160 -170.

What cooler did you use?

[sailsmen]

Watch you don't end up raising your coolant temp in order to drop your trans temp, particularly if your trans temp is within the range.
In some cases all that is needed is a shorter schedule for changing the trans fluid.
Compared to a motor rebuild a trans rebuild is cheap!

[napolitano]

We're good. Coolant temp stays 170 to 185the maybe 190 on a hot day. I have to ask DR which tranny cooler we used. The Reische thermostat works good for the cooler temps.

I noticed my coolant temps are higher than normal (comparing to the past years in the summer).

I've really been thinking getting the Reische thermostat.

[napolitano]

Works great. Just make sure to change your fan settings afterwards. Also if you have to go to the parts store make sure you remember to wear shoes. Landy knows what I'm talking about.

oh yes. i was easily over 200 when romping in summer. now 190 is hottest ive seen. 185 at 80mph now.. long coolers work well.

+1. I have 170 stat, and rear head cooling mod. works well. my coolant on a 90f day on highway =180-184

[sailsmen]

The Reische Thermo does not increase the heat dissapating capacity of your system.
It only allows the coolant to run at lower temps when the heat dissapating capacity is less than max. Example on a cool day at the track.

I removed the stock cooler when the stock trans broke. Now I'm running an F-350 Superduty cooler mounted in the stock location, deep sump pan and a remote thermostat. The highest temp I've seen in the pan is about 175-180*. All through a Lentech trans and 9.5" convertor. Coolant temps aren't noticably higher than before, it just gets there quicker.

If you want 180F coolant you need a 170F stat as it opens sooner. Riesche works very well for me with ambient 90+ temps in August goosing it. It took 5 minutes idle time of sitting still in the sun to hit 191.

My MM runs like a horse with the timing advanced - Even in the summer heat. No predetonate issues.

edit: I also have rear head cool mod and an EMP, not just the r170

not to derail this thread. nice setup, Lentech has a great rep. I added a in line thermal bypass. 2 total as I drive in the winter. 9.5 converters make a lot of heat, my fluid was over 200 quite a bit before my 22k mini max cooler and I already had a deep pan.

temps from pan may be cooler than inside. I read trans temps from PCM, how are you reading yours from pan sensor?

im using the cooler that came from a F150 and my tranny temps also stay between 160 and 170 even with the supercharger and running hard its stays below 170

with the ac on my coolent temps go over 200 but with the ac off it stays under 200 and its been hittin a 100 latley here in GEORGIA

Same here, the highest I've seen with the AC off has been 202 but it usually sits around 198-200 on hot and humid days.

[massacre]

When we installed a Darrin trans in my buddy's KB Terminator, we used a B&M supercooler(with fan) and a deep pan with AN -8 hoses. Trans has a transbrake and triple disc converter.
Temps never get above 165. NEVER.

FWIW

Autometer trans temp guage with sender tapped into the pan. The temps are typically lower in the pan than the PCM reads from what I understand, haven't bothered logging it, though.

I needed to add the thermal bypass because in the winter the trans temp wouldn't even reach 100deg unless I took the car through a busy fast food drive through. Even then it would drop right back down once the car started moving over 30mph.

What year Superduty?

[99SVT]

What year Superduty?

01-05. I don't know if they changed it for the new ones. It takes a bit of modification to get it to fit, the brackets have to get trimmed and bent to be able to mount it up.
