2015-2016 Tech Pack and Base GT350 Cooler Solution Discussion

[Jb350]

For guys with the tech pack, have any of you tried different trans fluid (not atf). I know there's a bg option and I'm sure there are others. Just wondering if anyone has tried it, and if not why?

People have brought this up with no success

Anything other than transmission fluid will cause shifting problems and damage to the synchro rings, a gear lube will not allow the synchros to engage as they should. The synchros need friction to engage properly and a gear lube will cause problems because it is designed to maintain a film between the working surfaces. A fluid with a higher viscosity than ATF will also cause more shear and heat inside the trans. I believe this has been addressed earlier in this thread as well as other threads.

Also, keep in mind that the Base and Tech cars do not monitor the differential temperature, there is no temperature sensor on the differential to put the car into limp mode. If your going to track the car extensively, the differential cooler is a necessity for prolong track use, but it is also the easier of the 2 cooling systems to install. The temperature gauges that I installed indicate the differential without a cooler stays 20-30 degrees cooler than the transmission without a cooler. So it would be capable of hitting 250 - 260 degrees on the track.

Don't the differential take a higher temp or take longer to heat up? Where typical track sessions are ok with cool down periods. There are plenty of people who track plenty of cars without differential coolers

Do you mean Engine Oil cooler? That is standard on all GT350s including base and tech.

Thanks, I thought they all had them, but was told at Track Attack they don't, and I looking thru the specs, it says the Track and R have Engine, Trans and Diff coolers...no mention of any cooler on the Tech...guess Ill have to stick my head under her and look! Thanks

On some back roads I noticed the axle temp was over 205 the whole time

All the original matterial said no engine oil cooler on base/tech but when the cars came out the oil coolers were present. That contributes to my thought that Ford didn't design the GT350 to not have any of the coolers, but took them off to meet a price point. I believe Ford found that it was too risky to remove the engine cooler after the track attacks.

Ignorance is bliss I guess. I've never had a car with anything more than the typical engine heat gauge.

Is 205 a lot?

Just to be clear, Ford's original packaging of the GT 350s was based at least partly on past information from buyers and marketing clinics from potential buyers before deciding what equipment to offer in each configuration. Apparently the majority of people surveyed said they would not be running their GT 350s on the track, so Ford didn't add the expense of coolers to the Tech Package. There also was a significant (but much smaller) group that indicated they would be hitting the track, so the Track Package was offered. In addition, Ford wanted to have a version priced at under $50K for the promotional value - which obviously worked, because almost every media report mentioned it.

Unfortunately, the real world didn't match the research after deliveries began, with a larger-than-expected number of buyers taking Techs to the track. When Ford saw that deviation from the original marketing plan, they changed the packages for 2017, because all the parts were already on the shelf. If the change would have required new parts, it could have taken 2 or 3 years for a fix. (If I had been making the decision, all GT 350s would have gotten all three coolers, just because the GT 350 in any form is such a heat-producing monster.)

Now all we need is an OEM fix for the unexpectedly high number of '16 Tech owners who are tracking their cars.

With only 5000 GT 350's produced not having all three coolers was a mistake. Even the 16 Camaro SS which is not their top dog has the much needed coolers ,engine ,trans and diff. I don't expect all 150.000 mustangs produced per year to have coolers. But the top performance Mustang with the name Shelby GT 350 should have them. The 17's do but what about the 15/16 owners. 66 % of all 16 350's don't have all three. Its almost fall and still no word from your friendly ford dealer

Dunno:-D never had that data before? At the time I had the below

Engine oil 230
Tranny temp 145
Axle 205
Cyclinder head temp ~210

The key question is, what should be the basic performance capability of a base or tech? This is not specific to track, as the car went limp within 3.5 minutes on the Autobahn and did the same on a back road in Canada. So, again, what should the car be capable of (without coolers)?

The autobahn was a claimed average of 163 on a track or street youd have period of braking to cool things down, so ive argued thats not really a relevant data point. Who knows what he was doing before that lol.

That is the question. I think from a logical point of view the non track should be capable of any street driving that would occur during normal use in the United States at US temperatures.

Disagree. Either it can perform or it can't and it can't. 526 hp and 8200RPM should be able to out perform US streets. Period.
