I thought the ideal temp for auto transmissions was around 180*?

 

That was my understanding as well.

On my 96, I sure don't have to drive it far when it is bitter cold out, before it will hit O/D though...... wonder if that was an advent of later years, or, my temp sensor is just lying to the PCM.

 

 

I've seen that chart before but it doesn't mention under 175*. I know the Earl's cooler in my car has some sort of thermostat that bypasses fluid when it's below 180*.

 

this is what i was thinking about using on my 81. $8 in fittings.

 

It's a high pressure line and I'll bet it'll blow those slip on lines off one day. I used one hose clamp and it blew if off in the parking lot and I had to get a ride to get 5 qts of ATF, so now I have three hose clamps and 2 zip ties on the line and 5 qts of spare ATF in my tool box.

 

maybe the newer trucks have higher pressure lines but both of my trucks have at least 2 rubber lines that are hose clamped on. i think with the correct hose clamps and high pressure hose i will be ok.

 

Sorry, but the sending unit is so far out of the flow of fluid, it's pretty much useless. Been there done that. That's why I suggest getting this. It's worth it.

Worm drive hose clamps have to be re-tightened after the first heat cycle, and then again after a few more heat cycles -- or they'll leak pretty much every darn time. It might take them a while to get started, but they'll leak eventually if you don't touch them twice after installation. After the second tightening, they'll hold on tight for years and years.

 

You learn something new every day. Thanks, I'm Going to go tighten all of my hose clamps again
