transmission cooling questions
Quote:
Do I completely eliminate all fluid routing to the radiator and use ONLY the aftermarket cooler? I dont want to overcool and I have the ecutune tcu from LAN so the temperature that the light comes on is lower than stock. Any recommendations? I want to stay away from putting an inline thermostat if that makes any difference. Appreciate the suggestions. |

It does not get cool enough where you live to need the heating from the rad to get transmission up to operation temps. As to size That I could not tell you, mine uses what I think of as typical sized its about a foot square I think. And maybe 2" wide. |

The biggest one is on my supercharged Claret. It's 10 X 12 X 3/4", and its actually too big SINCE I installed LAN's valve body! (LAN's valve body flows more oil so the transmission is cooler to begin with!) A 7.5" X 12 X3/4" cooler from Hayden/Imperial would be more than enough for Florida! PLEASE PLEASE PLEASE if you have the Subaru factory campaign filter, take it off! I just replaced an 80,250 mile SVX transmission and the campaign was so clogged I count blow through it! In Florida you do not REALLY need the cooler/warmer IMHO, and it is VERY VERY restrictiive to flow. I hope this helps. BTW, that same 7.5 X 12 X 3/4 cooler would be too big for a Winter driven SVX in the Northern states in the Contintal United States!

First time I've heard you mention this problem or heard of it at all....have you seen other factory campaign filters with the same clogging problem or could the tranny in your case been the source of debris and the filter was just doing its job ? Sure would like to think my trans filter isn't in need of removal... |

I have never seen one this clogged, but they all pose a restriction to flow, as does the stock in radiator cooler. The Hayden/Imperial coolers do not restrict flow, they just dissapate heat. Tom

Re: transmission cooling questions
it really depends on how you drive. i have a roughly 12"x10" cooler in the fender well and will still see the hot light when flogging the trans up the mountain. trans was rebuilt/updated a couple years a go and i do have lan's tcu.
filters are only a good idea if changed or checked frequently. i have replaced a lot of components because of add on filters. once they clog they stop fluid flow. whoever invented the aftermarket power steering filter must own stock in pump manufacturers.

I don't drive The Claret in 40°f weather because the lock up torque converter will not stay locked up since I installed his valve body. Tom

how did the valve body affect the shift feel?

I am not sure if I have it. Where do I mount the hayden/imperial cooler? Does the flow direction thru the cooler matter? |

Re: transmission cooling questions
The campaign filter would be attached to the driver's side front tow hook. You can probably see it below your battery tray from under the hood.
From underneath, it is right next to the lower radiator hose. You can't miss it if you have it. .

Re: transmission cooling questions
First trial installation of the external cooler + fan.
I made a bracket/shroud for the puller fan. There were two square holes behind the battery tray - I just pushed plastic nuts in these and use 5mm bolts for the upper stay. Drilled a few holes for the lower mounting. I may have to reinforce the upper bracket a bit - it does flex a little, just to make sure it won't fracture due to fatigue. The location is a bit risky from winter driving point of view - if I hit a hard snow bank the plastic bumper will give in and may foul with the cooler. I also bought a separate thermostatic bypass valve for fast warm ups and winter cruising. The fan will be controlled by a temp gauge with a programmable output for a relay. These are the parts I bought so far (Summit): Hayden Fluid Coolers /T |

Re: transmission cooling questions
The temp gauge and fan control still to be done.... I installed the thermostatic bypass valve and finished the cooler/fan installation too.
I wonder if there's enough fresh air inside the front fender? It should be a high pressure area when the vehicle is moving - it is directly connected to the radiator front area. /T |
