Transmission Probelms
Hello,
I have a 1996 F350 quad cab long bed, gas with a 460 4x4. My truck is currently showing these codes:
P1728 transmission Slip Malfunction
P0718 1-2 Shift Error
P0750 Shift Solenoid A Malfunction
and a side problem of P0401.-I replaced the sensor, and am still having the issue, may need to replace the valve.
I have read several threads, and articles but can't find the best route to fix the transmission. This truck is a weekend truck to go to home depot, and run very mild trails with the family, 6 times a year it will tow a flatbed trailer with offroad toys weighing 4000-5000 pounds. I plan to eventually do a cummins swap but that is in the distant future.
My question is what is needed parts wise to get my truck back up and running. I have read that a fully braised Torque converter is the only way to go, and if I do not put 2400 into the trans with will still suck.

The first thing to do is to replace the solenoid body. You don't have an electrical code for the solenoids, just a code (P0750) that indicates a mechanical failure in SSA. That failure can set the other two codes, too.

thank you for your advise, I will start there. Do you have a recommendation for an aftermarket trans cooler? It still only has the stock one?

So i purchased a new solenoid pack, dropped the pan. took the old pack out and installed the new one. Put the pan back on and started to fill with ATF. The overdrive button is now flashing immediately and i'm throwing two new codes P0755, and P0743. When putting in the fluid I had the truck running, would add some run threw the gears go back out and check the fluid and go from there. I slowly added 12 quarts and it dip stick says its full.
I tried to clear the codes after it was full and restart they both came right back on. Any advise?

The P0743 says there is an electrical problem with the converter clutch solenoid. The P0755 says there is a mechanical problem with shift solenoid B. I don't think that code can set until the truck goes through the gears. It should not be able to set immediately. Code P0755 can set immediately, that's the electrical code for SS-B.
There were some differences in solenoid bodies for E4ODs depending on year. Are you sure you got one for a 1996?

Mark will know better than I...
After some research, it seems the E4OD and 4R100 are basically identical in a lot of ways, so I figure the solenoids may be identical...

Well, no, that's not right.
The 4R100 is a renamed E4OD. The name changed when the Superduty was introduced. There are mechanical differences, but if it were not for the SAE (Society of Automotive Engineers) suggesting a common nomenclature for naming transmissions, I'm sure the E4OD name would have stayed with the trans through the end of it's run in 2004.
Those two solenoid bodies you show are NOT interchangeable. One is a PWM and one is not. The E4OD did not use a PWM solenoid body, the 4R100 (other than the early '99) did use PWM. Don't mix them up, it will cause problems.

Sorry, hopefully I was of at least a little help here!

Ok so part number TE140 is correct? what does this mean for the current codes? just not sure what the next step is.

It doesn't mean anything for the current codes. You have to diagnose if the problem is in the wiring, a connector, or you got a bad solenoid body.
