if your gonna replace the radiator anytime soon you could buy an aftermarket rad with a tranny cooler built in....that would be nice!  i don't know how well those work though??  and are the tranny cooolers you guys are running thermostaticaly controlled??

still, that way is ghetto.

Ok...when you say it is "ghetto" to me that sounds like it is put together like crap. Not good craftsmanship....rigged! :icon_cool:

The stock cooler is good sized and thick. Just in a bad location to save on space I guess. If you were to front mount it I think it would work pretty good also. :icon_cool:

I got friends running all aluminum rads and intercoolers with custom made aluminum brackets and it looks real good so if I needed to mount something up there it would be a top notch solid bolt on deal. I didnt have good luck with those copper push thru spikes, they wore a hole in the rad. plastic might not do as much damage though. and I dont think I would use the aux cooler up there if thats what you mean. I would be looking for something bigger like a new aluminum one that can really keep the temps down.

I think what I'm gonna do with mine is link up two of the stock coolers together in front of the radiator somewhere (I have two spares laying around anyway, so why not). Depending how it works out, maybe I'll just ditch the one in the stock location altogether.

..obviously, make sure you're adding extra fluid to compensate for the larger volume you have to fill..

the tgp is more of a full size car though :icon_confused: and the torque of the motor is def. full size type application. yes a big ass aluminum radiater would be ideal. you need to at least out-do the stock set-up.

Just remember, you can over cool the Transmission Fluid.
There is no thermostat for the tranny cooler.

GangstGP

have you ever heard of a tranny wearing out prematurely or losing performance from too good of a cooling system? I only have heard just the opposite, that a tranny runs too hot and it only lasts 10,000 miles or less.

so, is performing the TB bypass gonna overcool the TB as well? only at like 0 degrees farenheit, or like 10 degrees below 0 maybe

I have heard of NUMEROUS non-performance based transmissions being prematurely damaged by overcooling the trans fluid. There are two transmission shops in town who use a bypass valve they  install for the aftermarket cooler when not towing something so it does not cool too much. Now that is on heavier duty diesel pushers...but they also recommended I do not use my 15,000 B&M on the TSTE in the winter months because of the same overcooling issues. They did not try to sell me the bypass...they just advised against the cooler in the cold months. :icon_cool:

What does the Throttle Body bypass have to do with Trans Coolers????

GangstGP

 so you say it will fail if its too cool? or do you know? I KNOW they will fail if they get too hot.

like what happens when the oil is too cold? it gets a little thicker right? too hard for the pump to push it? more reasoning please.

and the TB can seize if it gets too cold and ices over. this has happened to me one night when I started the car and drove it when it was super cold outside and my car was a rolling iceberg.

I could see a monster cooler being used on a race car, but not on a daily driver car like mine will be

what about relocating and upgrading the aux cooler and keeping the radiater hooked up in the system as well?
