Friday I'll be doing some maintenance to my truck, its a 97 F250HD, 5.8L 2wd. I know it's 4-speed with electronic O/D (button on the end of the shifter). I've had some hard shift and "limp home" issues, so I'm planning on draining (NOT flushing, just draining) the fluid out and replacing the filter, but I've noticed there are several options. How do I tell if I have a E4OD or a 4R100 or a 4R70W (they're all 20-bolt to my understanding) and how can I tell if I have a deep pan or a shallow pan?
E4OD vs. 4R100 depends on year as the 4R100 replaced the E4OD in '97, so it could be either.
At about 40 seconds he gets into differences, with the killer at just about 2 minutes. Sensor location. If you have sensors on the top near the front and again on the top at the rear, 4R100:
What is the trans code for the 4R100? Or is it the same as the E4OD? I always forget its as easy as checking the door frame for this stuff on this truck.

Thanks in advance!
Those are easy questions. The 4T70W was never used with a 5.8L in a truck. So that's out. The first year of the 4R100 was 1999, so that's out. You have an E4OD.
Two wheel drive E4OD transmissions have the shallow pan and four wheel drive E4OD transmissions have the deep pan.
While we're on the subject, where is a good place to install a transmission temp probe? It's an old, heavy, high mileage work truck, I'd like to keep an eye on how warm things are getting.
Normal operating temp for a E4OD is up to 240 degrees. Mine runs around 200 in traffic. Above 240 and you are burning stuff up. As for the temp probe... easiest way is to mount it inline with hose going out from the tranny and into the cooler and as close to the tranny as possible for a somewhat accurate temp readings. I believe there is a test port on the side of the E40D and somebody out there has a sensor & gauge combo for this. Check JEGS or Summit Racing. Your 1997 F250 should be OBDII and you might try some of the Bluetooth OBDII scanners with your smart phone. This setup might give you tranny temp with no holes or wiring to mess with and the scanners are cheap. I would check for you but the only 5.8L I still have is (2) of the 1994 Lightnings. Too early for OBDII or MAF.. just a simple fuel injected engine.
In my opinion the test port on the driver's side of the trans is the best place to put a probe. Many people think the pan is a good idea, but I don't. That's the coolest place in the trans, and the last place to show when the trans is getting hot. The problem with putting the sensor in the cooling line is that you're going to get wildly fluctuating temperatures. Some of the temps you will see will scare you. And it doesn't mean anything is wrong. This line is output from the torque converter. When the converter is unlocked this can spike up to and even over 300°F and nothing is wrong.
Another option is to drop the tranny pan and weld in a threaded bung ($10) for your sensor.. Actually not that hard at all.. If you can spend the bucks I would swap the pan for a higher capacity pan and service the fluid / filter at the same time.

Reason: Wrong info.. answering (2) questions at same time and mixed up the thread. One was for an oil pan and one was for a tranny
I agree with Mark.. the test port on the side of the tranny is the best location for the sensor to give an accurate temp reading. Make sure the quality of the gauge and sensor are good.. last thing you want is to install all of this and have faulty parts.
Sounds like maybe an VSS problem.
Does the speedometer work OK with a steady needle?
Have checked the codes? If not do that first.
I would also think you have a OBD-1 truck an not OBD-II.
