Transmission Problem
I've got a 1996 F350 XLT, 2WD, Automatic E40D with 93,000 miles, and I think the transmission is giving up on me.
It revs high before switching from 1st to 2nd, and then when it does, it's a *hard* shift. Generally, it revs up to about 2500 RPM before finally kicking over, or, sometimes I have to let off the gas and try slowly pressing down on it again to get it to shift over, and its still a hard shift. I checked the fluid and there is plenty, but it's an orangish-red color with small black streaks (that could just be from the dipstick though). Fluid was changed less than a year ago, so I feel like it should still be the dark red color that it was when I put it in there.
Any way to confirm my transmission is bad, or could there be another problem? it's not chipped, I don't tow, for the most part, everything on the truck is stock.

I had to replace my trans. right many years ago. Mine started when the gear shift lever started blinking. The OD light at the end of the shift lever.
Now back then I was putting all the goodies I could to make the Ol Girl run. I wound up putting a Brian's Truck shop Tranny in it.. all steel gears an 103 sq in. of clutch
How does the fluid smell??
There are some great great guys here that can help you more, know a lot about the E40D

Get the codes read. The places that read codes free CANNOT read these codes. You need either a good independent shop or a Ford dealer.

I'm going to get the codes read before I do anything crazy, because I know it could very well be the TPS. I just wanted to make sure the fluid part was ok, because I've always been taught that color change can mean bad things. I've replaced the VSS twice already, the first time with an Autozone part, the second time with a Ford part.
It smells like normal transmission fluid, but I'm not sure what I'm supposed to be smelling for. I replaced it with Mobil 1 ATF fluid almost a year ago. I replaced it because back then it has started doing this problem, and it's progressively gotten worse. There was some metal shavings in the bottom of the pan, but not a whole lot and nothing big

Interesting find... There is no EEC under the hood on either fender. There's an OBDII connector on the passenger side of the truck, that doesn't activate when you plug a scanner in. Fuse is good, wires looked good.

The OBS trucks use a special programing through the OBD II port under the passenger glove box. Most DIY code readers can't read the PCM.
Some people use the software AE (Auto Enginuity) but I don't know for sure if it can read the transmission codes.
Torque Pro with a Bluetooth ELM device can read some of the live data from the truck. Transmission codes, I don't know
Car gauge pro with a Bluetooth ELM device can read PCM codes and do injector buzz and contribution tests. Transmission codes, I don't know.

I'll still give that a try, but I want to see if my thinking is straight on another possibility I didn't even think about.
An E40D blowing out in a mostly stock truck that hasn't done any towing and doesn't do a whole lot of hard runs and is at only 93k miles seems extremely unlikely to me.
Could the EBP Tube cause this? If not enough pressure is getting to the sensor, then it wouldn't shift immediately was my thought process.

These e4od are one of the main weak points of the truck...

I'll keep it all in mind. Also, I guess while I'm here. I'm looking into getting a scan tool to keep at home. Obviously AE is the one I'll most likely look into, but do the Aeroforce Interceptors work in the our trucks? And if they do, does anyone know if they read transmission or just engine codes?

Interceptor DOES work in our trucks; one of the few that do. You have to let them know your year and model so you get the right version. It can definitely obtain engine codes. I would assume (hehehe) that since the PCM controls both the engine and automatic transmission, and stores the codes for both, the Interceptor should also obtain transmission codes, but you should contact Aeroforce Tech to confirm.
I would check for you myself, but my trucks can't throw transmission codes.....

EBP sensor pipe does clog up.
I just replaced mine in 15 min with brake line and I bent it up to go behind alt since no intercooler on mine yet.
some snake them out with speedo cable and a drill but mine was too plugged up and the 90 bend was too tight for my cable to go through
I cut off at manifold and used 5/8 wrench to take off fitting and matched up line at store and flared after using the ford ends on it.

Update: I pulled the sensor off the EGR tube and the diaphragm is in bad shape (I work in x-ray labs, so i shot the sensor) and I snuck a speedo cable down the tube and it won't pass more than 3 inches down before it gets stuck. I decided to buy a new tube and sensor (got both from Autozone) and I'll replace those some time next week.
Aeroforce got back with me about the Interceptor. "It reads power train codes, which includes transmission codes P0700-P0899." I've got a spare gauge spot up for rent, so I think I may order one of those.
