Rep Power: 0 Transmission Cooler?
I have read something about there being a cooler that you can get for you transmission to prevent some of the problems the 01' has. Mostly because the entire reason I think the 01 transmission has problems is because of overheating. So what kind of brands are there that are suggeted, and has anyone here put it on there 01' automatic transmission? Is it possible to get a guage for the transmission tempature, to install in your inside cab so u can monitor it?

Rep Power: 0 I have blown one trans on my 01 Auto LX and the tech at Honda told it was from overheating and recomended getting one. He suggested getting a B&M one, that is what he has in his Civic

Automatic Transmissions
OIL TEMPERATURE MEASURED AT CONVERTER OUTLET TO COOLER:
300° F= The maximum allowable temperature. This is the recommended place to install a temperature gauge or sensor. Do not allow the converter outlet temperature to exceed 300° F. The temperature at this location will vary significantly because of load, hill climbing, etceteras. If the temperature reaches 300° F, reduce throttle. To lower transmission temperature with transmission in neutral, run the engine at 1,200 RPM for at least 2 - 3 minutes while keeping a close check for signs of engine overheating. A transmission in a heavy throttle, stall condition (a typical situation is rocking a vehicle stuck in mud, sand, or snow), may increase temperature at a rate of 1° degree per second of stall.
OIL TEMPERATURE MEASURED AT OIL PAN OR SUMP:
150° F= The minimum operating temperature. Note: It is possible in low ambient temperatures to overcool the transmission with auxiliary oil to air coolers. Oil to water coolers in standard factory radiators will normally not overcool a transmission.
175-200° F= Normal pan oil temperature operating range.
275° F= Maximum allowable oil pan temperature for short durations during long hill climbs.
300° F= Damage occurs to internal transmission parts, including warpage of metal parts, degradation of clutches, and melting of seals. Transmission oil oxidizes, (forming varnish-like substances causing further clutch slippage and compounding heat build up) and transmission oil life is extremely short.
AUTOMATIC TRANSMISSION FLUID LIFE / TEMPERATURE RELATIONSHIP:
Automatic transmission oil can provide up to 100,000 miles of service before oxidation requires replacement, at an operating temperature of 175° F. Above this temperature, the oil oxidation rate doubles with each 20° degrees F increase in oil temperature. See chart.
DEGREES F MILES DEGREES F MILES
175 100,000 295 1,500
195 50,000 315 750
215 25,000 335 325
235 12,500 355 160
255 6,250 375 80
275 3,125 395 40
Note: Transmission oil and filter should always be changed more frequently when driving with heavy loads (RVs), typically at least every 25,000 mile intervals, since converter outlet temperatures then normally far exceed the ideal 175° F.
