I mentioned a problem in another thread but thought I'd repost it here with the response I received from Rodney so that everyone can see:
Problem: driving the cruiser to work after installing the Extreme Valve Body from Rodney @ Wholesale Automatics, and so after driving for almost an hour, I was nearing my destination and slowed down from 70 to 35 as I made my exit and lo and behold the AT Oil Temp light comes on. F@@&@!!! See my many previous posts about this. So I realized that this only happens when I slow down after cruising for some time. My lines have been triple checked and the flow rate is fine. I have a new external trans cooler in front of the radiator (I used Georg's recommended brand). The radiator was replaced OEM last year. I also just had a new torque converter installed with the valve body. I am at a loss. Could the trans cooler in the radiator be not working? As I said, the flow rate is fine. I'm running synthetic fluid. Rodney's valve body came with a new screen and the old screen looked fine but I replaced it anyway. I'm thinking of installing an aux fan in front of the aux cooler. I am running stock 4.11 gears on 33" tires. I have 4.88's but they are not installed yet as I am wavering on those versus 4.56. I have no plans to ever go bigger on the tires so 4.88 might be overkill. Thoughts??
so I sent this same note to Rodney and his response was great so I thought I'd share it with everyone here:
Hi James its Rodney from Wholesale Automatics,
This is in fact normal, When the torque convertor lock-up comes on it stops the oil flow through the torque convertor and because the convertor is basically stuck between a hot engine and a hot oil pump the oil in the torque convertor over a very long time normally more than 45 minutes will get quite hot even though the oil temp light and oil temp gauge if you have one says that all is still normal. But when you slow down and either stop or come into a town the lock-up will release and the super-hot oil will then go past the temp senders and this is what you are seeing. Only 2 ways to fix, 1/ put one of our Heavy Duty Billet torque convertor in that allows for the flow to continue while the lock-up is on “or” every now and then when on a long trip slow down to under lock-up speed for a few minutes to flush the hot oil out and then continue. Took me 2 years to find this problem and find the cure.
