The 'experts' claim that a 20 degree drop in tranny temps can double the life of a tranny.
As explained earlier, temps above 250 F cause petroleum based fluid to begin to break down.
The higher above 250, the faster the process. Synthetic fluid resists the high temp breakdown. But even with synthetic fluid, at high temps the friction material on the clutch plates 'unglues' and the plates wear much faster.

Ambient air temperature plays a major role. For the average driver under average conditions, tranny temps should be in the 190-220 F range. But towing, climbing long hills, or high speed driving in hot weather can cause temps to rise a few degrees.

My setup is like this: hot fluid leaves the tranny, goes to the remote filter, out of the filter to the factory cooler. From the factory cooler, it goes to the B&M cooler behind the grille.
Leaves the cooler and returns to the tranny.

So the fluid at the filter should be the hottest. I ran some errands; about 6-7 miles of driving through mostly residential areas, some stop and go. Engine at normal operating temp and ambient air temp of 45 degrees. When I got home I used a laser thermometer. The temp at the filter: 142 F. The temps at the aftermarket cooler ranged from 65-80 depending where I took the temp.

for even more cooling ability you could also put on a fin cuff that just clamps on the spin on filter too

do both

And those of us in Texas too

just picked up some 1-3 corvette servos hopefully ill be pleased.. and i wana throw a tranny temp in when i do pillar guages.. gotta keep an eye on my gears!

Its OK but the super servos are much better also if u want to do more for the trans get a cooler and the external trans filter I rebuilt my trans to a 65e I have super servos 1-4od trans temp a pod ex filter and the big b&m cooler and my temps never get over 173 but I don't know how it does towing yet

I have a situation I would like your input on. I am the original owner of an '04 Canyon that just turned 205k. I have been experiencing a shifting delay from 3-4 at around 45 mph. Once the truck shifts to 4th it will stay there until speed drops to about 38 mph. I have never changed the trans fluid or had it flushed.

So here's my question: is it too late to install a shift kit or tranny performance parts at this point? Would it be detrimental to perform fluid change or maint on it now? I have only had to tow with it once, so it's never been stressed by that situation. Just had to deal with San Diego's stop-and-go traffic for 8 years.

yes best save the money and do a rebuild when it goes or before the best thing for the 4l60e is to add a cooler a spin on filter and servos
