Another transmission thread
Have a 2000 Excursion, stock(ish) with 4r100. Towed with it about 1200mi with no issues, no OD light blinking. I parked the truck for about a month and it sat until today and I fired it up. Started right up and it loped for a second. While it was still loping slightly the OD light started blinking (in park) and stopped after 5-10 seconds as soon as the idle smoothed out. Truck shifts just fine. Hasn't always been the smoothest shifting transmission but it is unknown if it is the stock transmission. Truck has 252k miles on it.
My question is....Can the transmission throw a code without blinking the OD light and then show up later and start blinking? I can't replicate it and nothing happened while towing that threw a red flag.
One thing that worries me is that it is a 2000 without the radiator/atf cooler and no temp gauge. Fluid looks good, a little old but not burned or stinky. Have been meaning to change the radiator out but for a 2001.
Thanks

I added one of these, switched to Mercon V and added Baldwin BT839-10 external AT oil filter few years ago to my E99.
So far so good.

Why do you think it didn't have a problem when you started it up and the light started to flash?
The only way you are going to be able to fix this is by getting the codes read. The places that read codes free CANNOT read these codes. You need either a good independent shop or a Ford dealer.

No, it can't.

The hard to move shift lever is often caused by a corroded Transmission Range Sensor (TRS.) It's located on the driver's side of the transmission. It is the part with the wiring harness attached.
If you're going to try and fix this without reading codes, you're going to spend a ton of money and not get it fixed.
