Wouldn't bypassing the radiator cause the trans to run hotter? I've sways heard that running them both is the best way to do it.

If your stall is not locking it will definitely heat it up especially highway driving. What rpms are you turning at 70 and what gear? For instance I turn 2200rpms at 70 with 3.42's with converter locked. When my lockup went out a few months back it was turning 3000rpms at 70mph and the fluid was getting up to 230* in 75* air.
This might be your best bet.

Deciding factor; RPM, who built my trans, said bypass, so bypass I did and I have only seen the trans fluid go over 150* once, since I installed the cooler

If you are overheating now with the addition of the cooler I suspect you may have cut too short an arc with the rubber line restricting flow. Using the same cooler, no by pass, and running a 3600 converter it was rare to see over 180.

I think I may have pinpointed my problem guys. I removed my air dam a few years ago since it was rubbing on everything. I'm guessing that since the air dam isn't there to direct air towards the cooler there isn't a sufficient amount of flow to help cool everything.

Running cool without it?
Is your stall locking up?
NO it was running fine before stall

You just identified the common denominator.

Yea, it was operating normal, and I'm almost positive it's locking up. It feels like it locks up around 45mph. How do I tell for sure? This is the first stall I've had.
I mentioned it in the post before your first one. Post #22.

Perhaps I'm blind..stupid...or a little of both. Nowhere in this thread, do I find any statement about you just changing the torque converter, and how your problems started after said change.
Good luck....I'm out.

That's what was said in post #22. Either way, you haven't been helpful. This isn't the first thread of mine that you've been condescending on. I don't understand why you post if you don't have anything useful to add.

"I'm thinking either the cooler is too small. Or my stall isn't locking up.
