Custom tranny cooler lines/remote filter??

I Love this forum, as one can learn new stuff all the time, and I mean that in a good way not sarcastically. As I noted before TD is turbine doc, and not trans doc.

But inquiring minds have got to know; if it is a risk what do the trans experts that see a trans daily think the risk level is? & frequency they see this as being an issue in what they see in there shops from day to day.

If so risky why do mfrs used WTO exchangers, or fail alert us to the risk, now I'll be doing a rethink on the strategy possibly of my set up

I'll be adding trans fluid testing to my sample program, also be considering a periodic trans fluid pressure test as well, as part of my preventative maintenance schedule.

Don't the higher temps within a trans "boil off" moisture that may accumulate in small amounts,

Also what is unique in glycol coolant that dissolves glue used in clutch packs, a variation of glycol is used in large generator/alternator cooling because it has less propensity to attack the generator in event of a leak in the ATW (glycol substituted for the water) in this case.

I could fathom water/glycol causing lubricity problems of the trans fluid and that causing clutch packs over time, but I'm resistive to accept the notion one does not have time to detect it.

I've lost 2 transmissions due to leaks in the cooler inside the radiator. The tranny shop told me it takes less than a teaspoon of anti-freeze to disolve the clutches ,so there was no noticeable difference in coolant or trans fluid levels. By the time I saw tranny fluid in the radiator it was too late.


Bk, you said your time to detect it was too late, did the shop give any indication how long before the blend with antifreeze that this could be an issue, also with plethora of antifreeze blends out there, is one preferred over the other to prevent this from happening.

Also on same note would a synthetic trans fluid be "mo better" to keep a trans alive if there was a coolant intrusion.

They didn't really give a amount of time for it to start dissolving the glue and friction material, but I would think it would be fairly fast.One of the trannys Ilost was a t325 in a 80 toronado. I put in a used radiator and within a couple days the tranny started slipping bad.

I don't think it's the glycol but the water. I had a bit of moisture in the trans of my JD tractor and it screwed the clutch plates in the Hi-Lo clutch. The old JD mech. said it was the moisture. He was the GMCTD of JD mechanics.
