93 e40d HELP
hi all with no prior problems my trans started acting up. when the truck is first started and i move the colum shift down in the revers position it goes into drive. its the same with nuetral and well drive, but the 1st and 2nd gear column selections are still 1st and 2nd. so i no longer have revers and cant put the truck in nuetral to push it back. has anyone ever had this problem and if so please have some info. thanks to all

Two things spring to mind. First is that the internal shift linkage has become disconnected. You would need to drop the pan to see if that is the case.
Second thing is that the forward clutch has welded itself together. Check the color and smell of the fluid as that may give an indication.

thanks
thanks for the reply after reading your post i went and played with things a bit and oddly enough the truck will go in nuetral when up to speed, this being the case is the second of the two options still valid?

incorrect gear starts and neutral while driving is most commonly a failed MLPS.
nice quote for ya;
Regarding MLPS:
Wrong Gear Starts
Bad or mis-adjusted MLPS
Can cause wrong gear starts, no upshift, falls out of gear, and high line pressure = harsh upshift and engagements. May or may not set code 67/634 (MLPS out of position).
Note
MLPS is located on driver's side of transmission case.
MLPS adjustment
Place manual lever in Neutral. Line up I.D mark on sensor with l.D. mark on plastic bushing. Tighten bolts.
To check MLPS
1. Hook red lead of DVOM to pin # 199 (MLP sensor signal).
2. Hook black lead of meter to pin 359 (sensor signal return).
3. Set meter to ohms.
4. Move manual lever through the different positions and compare DVOM reading to chart below.
Manuel lever position
Meter should read:
P 3769 to 4608 ohms
R 1304 to 1593 ohms
N 660 to 807 ohms
D .... 361 to 442 ohms
2 190 to 232 ohms
I 80 to 95 ohms
Important
If the MLPS needs replacement, use Ford part # E5TZ-7A247-A. This kit includes a new style harness connector. You must replace the connector to use the new MLPS. By sliding the old wire separator from the original connector up the harness you can leave it in place as you install the new connector. This helps to keep the wires in their original location.
Note
Make sure you clean the harness connector with brake clean and apply some dielectric grease to the pins. This will ensure a good connection. Use Permatex part # 67V (dielectric tune-up grease). You can get it at most auto parts stores.
Not saying your MLPS is bad but I saved $40 going to Napa instead of a dealership when I replaced mine.
