Trans cooler upgrade - Ford 31 row versus Mishimoto 37 row

After putting off a transmission upgrade, my tranny finally overheated yesterday evening pulling my travel trailer. I have a 2003 ford 7.3l excursion. So now, I am finally going to upgrade the transmission cooler and need some help trying to figure out whether I go with the Ford 6.0l 31 row 5c3z-7A095B or the Mishimoto 37 row cooler.


I was unable to locate the core dimensions on the Ford 31 row 5c3z-7A095B cooler anywhere. Does anyone know what the core dimensions are on this cooler?


The core size for the Mishimoto mmtc-f2d-99sl is 25.25LX16.13hX1.25W


I saw someone post up on another site that although the Mishimoto has more rows it's core size is actually smaller. I would like to know what the core size difference is between the two coolers outside of the number of rows.


What I have been able to find on the Mishimoto MMTC-F2D-99SL trans cooler is it appears to be cheaper than the ford 31 row cooler and can be found just under $300 and has a lifetime warranty with a kit to install with 1/2" lines.


The cheapest I can find the ford 31 row cooler is around $470 and it appears if you buy a kit versus cobbling the parts together is around $60. Heard the only thing I would need outside of the installation kit with 1/2 hose and clamps is some flat washers for the lower bolts however some folks have said you need longer lower bolts. anyone know if I just need fender washers or longer bolts? Cant find any info on warranty from ford or dimensions.


I would appreciate any info you all may have to help me decide on what the better transmission cooler is before I decide to purchase one realizing the cheaper cost is not always the best options.


I have heard good things about both but was hoping to find someone who sells both and could give me some comparison specs and feedback from folks who have used them.


thanks for you review and response.

I'll try to measure my cooler later today. It's not the easiest thing to get to once installed, but I might be able to sneak a tape onto it.

Read this write-up in the meantime:

6.0 Transmission Cooler Write up.pdf

Also, now would be a good time to rebuild the bypass. If it is leaking, upgrading the cooler won't do you a bit of good.

I went with a Dorman brand 31 row cooler for my second transmission. I had put the Ford OEM 31 row cooler on the first one. I can't tell a difference between the two except for the price. The Dorman was less than $150 and its been working just fine for almost a year now. I'd recommend saving some money and getting the Dorman. Lots of places carry it...just do a Google search for the best price.

Has anyone ever heard of a Ford 31-row resulting in overheating?

I don't recall ever reading of any issues here on TDS.

Did you check Tousley Ford (AutoNation of White Bear Lake) pricing?

I just put the 31 row Dorman paid 130.00 on Rockauto.com and other than sourcing a couple of the fittings it went smooth. Upgraded the lines to 1/2" going into the radiator. I don't know if this really helps considering the hard lines going to the tranny are 3/8". I just have the factory dummy gauge so no actual readings to compare but the size difference between the stock is amazing.

I ordered the mishimoto tranny cooler yesterday and hope it is as good as the ford 31 row.

thanking about upgrading the tranny now. I am on my second one. first went up at 36K driving back from NC to Maryland when I bought it. Ford replaced it with a so called new one and upgraded my warranty from 3 year/36K to 6 year/100k. Currently have 180k on excursion and close to 150k on current stock tranny. with the overheating the other day, I think it is time to upgrade pulling a 10k trailer on occasions.

Been doing a lot of research on the net and have read great things about a number of folks, bts, John woods, BD, etc.

trying to make the tough decision and getting the best value for the buck. spoke to a local tranny guy in Hollywood Maryland who customs builds trannys and want to compare the specs to one like a BTS or one of the other highly referred 4r100 tranny builders.

does anyone know where I could get the specs on a BTS 4r100 Tranny and who in Maryland could install a BTS tranny?

Bts Is not doing to give up his how to secrets.

He machines certain parts to fit in extra clutches. Suncoast still sells machined coast clutch drum to fit 100% more clutches.

Center support is machined and a snap ring is used to prevent it from moving.

Sunshell is hardened.

Fully splined E4OD forward drum used instead of half spline 4r100 drum.

Accumulator Valve body upgrades.

Pump is modified for increased output. Usually convert to on/off pwm.

Then a quality billet cover triple disk converter to top it all off.
