Moody e4od
So I have a 1995 f-250 4x4 with the 460 and a E4od. So when I bought the truck I drive it two hours home and when I got into town it started shifting really hard and searching for gears. So I flushed it and installed a new oil filter because the oil in it was brown. Very brown. And smelled awful. So it shifts good, but what's happening now is that it shifts good in drive when it wants to. In the morning it works great but when I get in it to leave after school it shifts really late (around 2900 rpm) and hard. So I put it in first and then into second but when it's time for third and I put it in drive it shifts back to first. But if I stop shut it off for a few minutes and turn it back on it works fine. It only does this after it's been sitting in the school parking lot all day. I replaced the mlps but not the connector due to I didn't have time at the moment. Could it be the tps? Something mechanical? The od off light does flash when it's messing up. Thanks for the help in advance.

You need to get the codes read. That's the only way to know where to start. Without the codes all you can do is buy parts until you get lucky.
The places that read codes free CANNOT read these codes. You need either a good independent shop or a Ford dealer.

I doubt the dealer still has the equipment to read OBD1 codes. Even if they did you'd be lucky to find a worker there that knew how to use it.
Mark, on an OBD2 computer system, are the codes that some places can't read the P1xxx codes?
And on an OBD1 system, would the equivalent codes flash out on the check engine light?

Oops! I didn't read close enough. This is an OBDI, and you can read these codes with a volt meter.
Ford OBD Trouble Codes ?
In later models with OBDII you can use any generic code reader to read any code that turns on the check engine light. That's by federal law. Codes that do not turn on the check engine light, and that includes most transmission codes, need specialized readers.

They did this because the EPA made it a federal regulation. Why did the EPA do that? You'd have to ask them.

ah.thanks Mark.
well no luck in their FAQ.
well i recently had a 98 mazda 626 and it had the light on.i bought an obd2 reader but it couldn't pull the codes either.so i just drove the car until it rusted out.if i was able to get the code,i probably would have fixed it.so that one back fired on them lmao!
i just bought a '98 honda civic and the scanner does read this one.so i was able to replace an o2 sensor recently.burns cleaner and better fuel economy.EPA and me both win/win.
hopefully (but doubtfully) the EPA has learned it's lesson.if it wants vehicles to run clean for their life span,then they need to make reading codes readily available and easy with affordable scanners otherwise people wont pay shops for what becomes old jalopy's not worth the cost or effort to have read by techs and pricey scanners.
so which trucks of the era exactly are we not able to grab all codes from at home? any of the f-series '96 and up with either gas or diesel makes no difference?

Any emissions related problem will turn on the check engine light and any generic code reader can read those. So they have covered the emissions problems. Other problems that do not cause an emissions issue won't be picked up by generic readers.
I believe that's correct.
